  The skeletal growth rates of Porites corals are important indicators of ambient sea surface temperatures (SST). Three Porites corals collected from Yongxing Island, Xisha Islands, dated to 120-59 BC, 46 BC-14 AD and 30 BC-28 AD respectively, were analyzed for skeletal growth rates to reconstruct the local SST variations in the Rome Warm Period. The mean values of their growth rates were 0.88 cm/a, 0.90 cm/a and 1.12 cm/a, ranging from 0.53-1.24 cm/a, 0.58-1.53 cm/a, and 0.71-1.46 cm/a, respectively. The reconstructed average annual SST were 26.7℃, 26.8℃ and 27.3℃ respectively. The average SST in the Xisha Islands was 26.93±0.41℃ during the Rome Warm Period (120-59BC，46BC-28AD), 0.7℃ lower than the mean temperature recored from 1981 to 2010 AD.

  In this paper the statistical characteristics of per 24h intensity change for tropical cyclone (TC) are analyzed, the thresholds of tropical cyclone rapid intensification (RI) are defined by using the tropical cyclone best track data of Joint Typhoon Warning Center (JTWC) and the NCEP/ NCAR reanalysis data from 1990 to 2009, and with comprehensive comparison and analysis of initial intensity, the seasonal variation and spatial distribution characteristics of TC rapid intensification are given in different thresholds of tropical cyclone rapid intensification. According to the calculation, the paper defines the thresholds of tropical cyclone rapid intensification as 25KT, 30KT, 35KT, 40KT, which respectively represent the 88th, 90th, 93th, 96th percentiles of 24-h overwater intensity changes of tropical cyclones in the Northwest-Pacific area. The initial intensity of tropical cyclone rapid intensification will increase when the threshold increases. About 60% of tropical cyclones undergo RI during the period from August to October. And, most of the tropical cyclones undergo RI in the region of 125°E-150°E,10°N-25°N. It is found that the relationship between the vertical wind shear at different levels in troposphere and tropical cyclone rapid intensification is different. When the threshold of tropical cyclone rapid intensification is 40KT in 200-500hPa, 500-850hPa and 200-850hPa, only 9%, 5%, 7% of tropical cyclones can undergo RI. The correlation coefficient between tropical cyclone rapid intensification and the vertical wind shear at different levels are -0.15, 0, -0.04 respectively. So, it is obvious that the vertical wind shear in 200-500hPa is less favorable for TC to undergo RI. The vertical wind shear can be divided into east vertical shear and west vertical shear. When the threshold is 40KT in 200-850hPa, about 57% of the TC can undergo RI under the circumstance of east vertical shear.

  This paper develops a semi-empirical model for retrieving land surface temperature ( ) using AMSR-E data based on the passive microwave radiative transfer equation, in combination with the relation between vegetation depth and MPDI, and that between precipitable water content and land surface temperature. With this model, can be easily simulated from the brightness temperatures of AMSR-E 6.9GHz band and 10.7GHz band without any ancillary data. The mapping and validation results of China in 2009 prove that the average retrieval accuracy reaches about 2.51℃ (R2=0.79). It can be considered that the model is a simple and also effective algorithm to retrieve with passive microwave remote sensing data.

  Research At present the research on usage of cave index system recording surface’s rocky desertification development lies at theory's rudiments phase. Based on the data of dynamic monitoring of Shi Jiangjun Cave in an intense rocky desertification area, the paper analyzes the spatial-temporal characteristics of drips’ rate, pH and temperature of the cave and makes a preliminary exploration on the effect of rocky desertification. Meanwhile, the paper also makes a contrastive analysis between drips pH characters of Shi Jiangjun Cave and those of the cave in non-rocky desertification areas and provides corresponding proof from δ13C value of Shi Jiangjun Cave’s deposit. The main conclusions got in this article are as follows: In rocky desertification areas, vegetation on the surface is always damaged seriously and soil is rare because of erosion. Under such kind of circumstance, karst water is mainly stored in bed rock. So, the thicker the bed rock is, the more stable the variability of drips’ rate, pH value and temperature are. Correspondingly, the drips close to cave entrance are sensitive to environment with high variation. And also, the available amount of CO2 is scarce under intense rocky desertification environment, resulting in an abnormal phenomenon of higher pH value in rainy season than in dry season.

  In the study of public space value, the social action theory puts forward a framework of social action research based on the “field” structural space, and provides a practical method for the construction of public space value. Community has become an important carrier of the construction of public space value in the background of the appearance of public space value crisis in western countries, and has gradually become an important means to reconstruct the community public space value for its nature of social action. At present, the community planning in China, which practices as the local exploration innovation in the framework of urban planning system, has been difficult to adapt to the continuous growth of community action need under the background of civil society. Taking Yanyunxi, Liushuijing and Longzang communities in Beijing Street Subdistrict of Guangzhou as examples, the study shows that the three communities are facing the problems of deepen heterogeneous, reduced community capital, and obstacles of community action under the impact of business culture. To build more tolerance, more open, and more energetic sustainable communities has become the common desire and demand of the community residents. This paper discusses the construction of community operation space and the method of community promoting action, trying to construct community planning system to meet the public space value demand from the perspectives of “organization” and “field” with the new institutionalism theory.

  The relationship between land use planning and urban planning has become a hot topic in recent years. The publishment of the present land use classification systems in both kinds of planning has given an opportunity for their coordination. This paper gives a comparison analysis of the present and past land use classification systems for both of the planning. The conclusions are that the relationship evolution can be divided into three period: before 1997 the two systems were isolated; from 1997 to 2006 they were conflicting; and since 2006 they have been coordinated. The conflicts between the past two classification systems include those of land use focal points, classification system composition, classification method for development land, and spatial scope. The present classification system for land use planning shows four new points as compared to the past system: first, the planing system is coordinated with the current system; second, the current system is changed from three levels to two levels; third, classification method for development land gives more consideration to industrial sector characteristics; and fourth, it is much more flexible. The present classification system for urban planning shows two new points as compared to the past one: first, a classification system for urban and rural land is added; second, the classification system for urban development land is revised. At the end, this paper gives a table showing the relationship between the present land use classification systems of the two kinds of planning.

  Farmland circulation is the directional selection land use behavior of rural households, it can be divided into transferring-in and transferring-out. The characteristics of farmland circulation and the impact factors of circulation price with different circulation directions were explored by using the data from the survey of 467 rural households in Panyu District of Guangzhou. The conclusions are as follows: ①The characteristics of farmland circulation had some differences in different circulation directions. The transferring-out rate was higher than the transferring-in rate, the transferring-in areas were more than transferring-out areas, and the circulation rate in northern Panyu was higher than that in Southern. However, the difference in price of transfer, contract mode, difficulty level of circulation and transaction time was not significant. ②Analysis of impact factors of circulation price under different directions of farmland circulation with multivariate regression method showed that the regression results of transferring-in were better than those of transferring-out, and the circulation mode and transfer time had different effect in different models. As the characteristics of transfer-in and transfer-out are dirrerent, the studies of the two kinds of farmland circulation should be something different.

  Land Use/Cover Change(LUCC) is a core issue of global change and regional sustainable development research. Coastal zone is the land-ocean interaction area, which is much more sensitive to human activities. The exploration of coastal LUCC is significant to meet the challenges of the environment and nature. Yancheng, a typical research area in Jiangsu coastal areas, is selected to characterize coastal land-use and land-cover changes with five series of Landsat MSS/TM imagery from 1978 to 2007. The classification schema is newly-developed based on the existing schemas as well as the geographical background of Jiangsu coastal areas, and PCA classification and post-classification comparison are used to perform image classification. With the series of land use/cover change results, the land use structure, land use change quantity, land use change rate and spatial change pattern are analyzed and calculated based on GIS. The results show that:(1) The change of land use was significant during the study period, the land use structure of Yancheng was relatively stable; cultivated land was the main agricultural land use type, but urban construction land had a sharp increase on land use amount and land use proportion in recent years; (2)The land use change quantity and change rate were very significant in different periods. The change of construction land was the most significant, and the urban construction land increased 3.34 times, i.e. from 167.01 km2 in 1978 to 725.19 km2 in 2007, and at the same time the land use change rate reached 15% from 2004 to 2007. (3) From the perspective of spatial change pattern, the central urban districts of Yancheng, especially the Economic Development Zones and newly-incorporated Yandu District, had a rapid urban expansion; simultaneously some newly-developed coastal ports such as Binhai Port, Dafeng Port and coastal towns nearby also had a high-speed growth.

  Supported by GIS and based on landscape disturbance index and landscape fragility index, a comprehensive evaluation index system for landscape ecological security is constructed, the change of land use landscape ecological security in the Liuxihe watershed in 2000, 2005 and 2009 is analyzed. The results show that: 1) The influence of human activities on watershed landscape ecological security pattern was significantly enhanced, forest and cultivated land decreased, while construction land and orchard land increased, leading to the increase of fragmentation and isolation of each landscape type，and the dominant landscape types were changed from forest-grass land plus cultivated land to forest-grass land plus orchard. 2) From 2000 to 2005, more than half of the patterns of landscape ecological security changed, and from 2005 to 2009, the transfer rate of watershed landscape ecological security was about 60%, and 90% of the spatial patterns of landscape ecological security of the watershed changed; 3) In 2000 all the landscape ecological security indexes (ESk) of the watershed were more than 0.6. In 2005 the areas with indexes of 0.6 or higher (ESk ≥0.6) accounted for 98.48% of the total, and the areas with ESk ≥0.8 decreased by 55.93%, as compared with those in 2000. In 2009, the areas of ESk ≥0.6 reduced by 72.93%, as compared with those in 2005, which were mainly distributed in the upstream of the basin. Now there is no area with ESk ≥0.8 in all of the watershed. Its landscape ecological security is decreasing.

  The community characteristics of the Fengshui-wood including Erythrophleum fordii in Guangzhou were studied based on sample plot survey. The results show that the community type had the transition characteristics from tropics to south subtropics. It is found that there were 98 species of vascular plants belonging to 80 genera and 50 families within a quadrats area of 4000 m2. The flora was dominated by tropical and subtropical element. Erythrophleum fordii, Castanopsis chinensis and Gironniera subaequalis were the constructive species of this community. Community biodiversity analysis reveals that Margalef richness index and Shannon-Wiener diversity index of tree layer and shrub layer in this community type were relatively high, being within the range of south tropical ever-green broadleaved forest indexes. The basal area at breast height was very large and up to 36.92 m2/hm2. Community frequency analysis shows that these Fengshui woods did not agree with the frequency law of Raunkiaer. It also shows that small population had large frequency and there were many occasional species.

  From the perspective of resources, market, policy and industrial transfer, combining other quantitative and qualitative research methods such as semi-structured interviews with enterprises, case analysis, location entropy and specialization coefficient, this article analyses the development history, the present situation, problems and growth mechanism of the regeneration non-ferrous metal industry cluster in Qingyuan. It is found that the dynamic mechanism of industrial cluster is in constant evolution along with economic and social environment changes. In the initial stage of the formation of industry cluster, in addition to the traditional elements, the historical contingency and the market spontaneous regulation provide possibility for the generation of clusters. And in the middle- late stage, as a system provider, the government plays a very important role for the development and evolution of the cluster. Specifically, the endogenous resource advantages of cluster include huge volume of renewable resources and labor resources. The exogenous institution advantages include the government’s policy support, the institutional arrangements of inter-regional industry transfer, and conscious introduction and cultivation of leading enterprises. The endogenous and exogenous dynamics commonly prompt the cluster development of the high-end elements, the transformation and upgrading of the industrial cluster, the formation of the cluster production network and specialization divisions. Such experience as the endogenous impetus for the economic rise in less developed areas could be important reference for other cities to develop renewable resources industry.

  Taking the Poyang Lake Ecological Economic Zone, the Urban Zone along the Wanjiang, the Wuhan City Circle and the Changsha-Zhuzhou-Xiangtan Urban Agglomeration in the Yangtze Midstream Economic Zone (YMEZ) as research units, the paper analyses the spatial and temporal economic difference and its evolution in the studied area. In the paper the total permanent resident population from 1995 to 2011, GDP, and per-capita GDP are taken as measurement indexes, the methods of standard deviation, coefficient of variation, Theil index, and spatial autocorrelation are used, and softwares of ArcGIS and GeoDA are employed to support the study. The result shows that the general economic development level of the YMEZ is continually rising, but the overall absolute regional economic differences are expanding, and such expansion trend has been gradually being enhanced since 2000. The relative economic differences in the YMEZ are not significant. The economic development of the Wuhan City Circle was relatively the fastest in the four major economic zones above-mentioned from 1995 to 2003, which of the Poyang Lake Ecological Economic Zone was the slowest in the same period. However, the economic development of the urban zone along the Wanjiang became the fastest from 2003 to 2011, while the development speed of the Wuhan City Circle decreased during that time. The internal economic difference in all the four economic zones is still expanding, and that in Wuhan City Circle is the biggest. It can be seen from the perspective of spatial evolution that the spatial difference of economic development in the region keeps increasing, the spatial concentration trend keeps weakening, while the diffusion effect is gradually increasing, the the polarization phenomena appear in high level development cities, and the leading role of the central cities is not obvious. The main reasons that cause the economic differences are the influences of traffic location, regional policies, the development of central cities, resource endowments and industrial structure.

  With the industry's competitiveness evaluation index system of transportation equipment manufacturing, by using principal component analysis, TOPSIS method and cluster analysis, the paper evaluates the degrees of the transportation equipment manufacturing of China in 2010. The results indicate that the competitiveness distribution was imbalance in China and the industry competitiveness weakened from east to west. Those having strong competitiveness included Jilin, Shandong, Jiangsu, Shanghai and Guangdong which are located in Northeast, East, and South China, respectively. In middle and west China the Competitiveness level was not high and there existed some "collapse" regions such as Jiangxi province in middle China. In order to promote the development of transportation equipment manufacturing in the country, some relevant suggestions are put forward in this paper: 1) Develop the transportation equipment manufacturing according to different development stages and local conditions for each province; 2) Strengthen the division of labor and cooperation among the provinces, in order to achieve complementary advantages; 3) Establish a long-term support mechanism; 4) Increase capital investment and reduce the difficulty of financing; 5) Cultivate the capability of independent innovation.

  Shuzhu Chong, an urban stream in Guangzhou, is situated in Haizhu District which Cantonese call Honam. Hundred years ago, during the middle Qing dynasty, the area along the stream was prosperous and bustling, where row upon row of shops, restaurants and hotels lined the water front, some famous temples were distributed, and some beautiful Chinese style garden residences were built by the rich merchants of the Thirteen Hongs. It was the earliest urban area in rural Honam, and also one of the earliest tourism regions open to foreigners in the Qing Dynasty. The booming of the Thirteen Hongs brought about a rare chance in the development of the Shuzhu Chong area, which lay across the Pearl River from the Factories at Canton (Guangzhou). A great number of visiters from the Thirteen Hongs and other places in the city as well as from abroad visited the area. The temples and the rich merchants’ garden residences even served as guest houses to receive foreign diplomatic corps. since the late Qing Dynasty the Shuzhu Chong area gradually had declined, as the political and economic situation of China changed. In the 1960s the stream was covered and turned into an underground drainage dicth because of the serious water pollution. Since then Shuzhu Chong as an urban stream with its name has disappeared from the map of the city. Many historical sites in the Shuzhu Chong area have been damaged or destroyed. At present many local residents know little about the stream or even do not know there was a stream there. The paper suggests that the heritage of Shuzhu Chong shoud be treasured. It should not be wiped out from the memory of young generations. The historical-cultural style and features of the stream might be reproduced. For that purpose a historical and cultural tourism region be constructed.

  Based on the development of research on new urban district, foreign new urban district research can fall into three stages: 1) from 1890s to 1950s, the research was oriented at functional persuasion and social demand, and the research field included functional morphology of new urban district and development practice of satellite town etc.; 2) from 1950s to 1990s, the research was oriented at functional balance and economic demand, and the research field included development practice of new town and new industrial district etc. ; 3) since 1990s, the research has been oriented at policy guidance and ecological requirement, and the research field includes ecological new town, suburbanization and edge city, planning and design of new urban district and industrial and social problems of new district etc. By contrast, Chinese new urban district research also falls into three stages: reference research on foreign theories from 1978 to early 1990s, research on development zone from 1990s to early 2000s and research on comprehensive new urban district since 2000s. Relevant research fields include industrial development, land utilization, space structure, transportation development, management system, life cycle and transition and individual cases of new urban district development etc. Domestic and foreign researches have significant differences in research background and purpose, content and method. This paper also looks into the future main research direction of new urban district in China: 1) the function of new urban district development for urban space growth; 2) evolution and life cycle of new urban district; 3) new urban district development mode based on the concept of saving; 4) application of research methods of new urban district development.
