  The Dapeng Peninsula is located in the eastern part of Shenzhen, Guangdong. The peninsula has a wide variety of different coastal landforms. In this paper, the basic features of the coastal landforms of the Dapeng Peninsula are discussed. The results of field investigations and laboratory experiments show that the peninsula’s coastal landforms can be classified into three groups: rocky coasts, depositional coasts, and biological coasts. As lying in a fault uplift zone, the rocky coasts occupy most of the coastal line of Dapeng Peninsula. Typical costal erosion landforms such as sea cliffs, wave cut benches, sea caves, sea arches and sea stacks can always be found on the coasts. Depositional coasts of the peninsula develop in bays between rocky headlands. Generally, a barrier-lagoon system is formed in the bay which is deeply embayed with a stream flowing in. In the bay without streams, a bay head beach develops. The middle of the peninsula is narrow and shaped somewhat like a dumbbell, and muddy beaches are formed in its eastern coast because the coastline concaves deeply landwards providing shelter from wave attacks. Mangroves grow in the muddy beaches, as well as the lagoons. Coral reefs are found in the shallow water areas around the coasts of the peninsula. According to the field evidences and the dating of the sediments of the Dapeng Peninsula and its surrounding areas cited from the previous studies, the main important factors controlling the development of the peninsula’s coastal landforms were geological structures and sea-level changes during Holocene; The peninsula’s coastal landforms began to develop after middle Holocene; no strong structural uplift had happened in the areas of the peninsula since middle Holocene; The sea level had a higher standing after the middle Holocene on the coasts of the Dapeng peninsula.

  With the rapid development of the city of Guangzhou, human engineering activities have exacerbated the natural environment. In recent years, a large number of key projects construction have been completed, such as the Wuhan-Guangzhou high-speed railway, several serious geological hazards have occured in Jinshazhou area. In this paper, on the basis of the field surveys for years, the causal factors of the geological disasters are analyzed systematically, an evaluation index system is established, and the evaluation methods of geological hazard susceptible degree are presented. According to the geological disaster evaluation grade, Jinshazhou is divided into four regions, which are high risk region, medium risk region, low risk region and least risk region. The central and southern parts of Jinshazhou where the Wuhan-Guangzhou high-speed rail tunnel passes through are of high risk region of geological hazard occurrence. In that region there are buried karst areas, the geological environment is fragile, and large-scale construction is inappropriate. The eastern part of Jinshazhou, where Xunfeng fault(F3), Shabei fault(F4) and Baoli Xiziwan fault(F5) pass through, are of medium risk region. In the region there are adverse rock soil masses, and the major geological disaster is land subsidence. The southeast and central parts of Jinshazhou, where there are less soluble rock strata, are of low risk region. The western part of Jinshazhou is a hilly area and is of the least risk region, where there develops no karst and have no basic condition for geological disasters.

  Study of Magnetic properties of marine surface sediments are gradually proved to be one of the effective means for source analysis of marine sediments. In this paper samples from 39 stations in the sea areas around the Hainan Island were collected to analyze the magnetic characteristics of the surface sediments. It is shown that the low frequency magnetic susceptibility and frequency-dependent susceptibility in the areas have significant spatial differential features. The high values are mainly distributed in the southern sea area of the Hainan Island, while in the eastern and western sea areas the values are gradually decreasing from the coast to sea. The influence factors of magnetic susceptibility analysis shows that the susceptibility of the marine surface sediments in the study area is mainly contributed by terrestrial material, so the spatial distribution characteristics of low frequency magnetic susceptibility and frequency magnetic susceptibility can indicate the diversity of the input of terrestrial material. The studied area can be divided into four parts based on the Q type cluster analysis combined with the geographical location of sampling points. In the sea area to the east of Hainan Island with a water depth over 100 m (Part I) the sediments are mainly from the Pearl River system and to some extent are affected by the terrestrial material carried by the coastal rivers of west Guangdong. In the sea area to the east of Hainan with a water depth less than 100 m and the area to the south of Hainan (Part II) the sediments are mainly from the coastwise eruption and coastwise rivers of the Island; In the northern waters of the Beibu Gulf (Part III) the sediments are from Qiongzhou Strait and coastal rivers around the Gulf; In the sea area to the west of Hainan (Part Ⅳ) the sediments are from the rivers and coastal erosion in southwestern Hainan and from the materials carried by the ocean currents from south to north. The study shows that the combination of low frequency magnetic susceptibility and frequency dependent susceptibility can effectively indicate the source change in the offshore surface sediment.

  At present the emissions from agricultural and industrial activities are relatively neglected in the influencing factors analysis of greenhouse gas emissions. In this paper, the method of 2006 IPCC Guidelines for National Greenhouse Gas Inventories is used to calculate the emissions of greenhouse gas of Fujian Province from 2001 to 2010. On the basis of the carbon dioxide equivalent which is converted from greenhouse gases, we have analyzed the influencing factors of greenhouse gas emissions by the model of LMDI, and introduced some new indexes to explain the influence of the emissions from industrial and agricultural activities. The results show that although the total emission of greenhouse gas was increasing during the period of the study, its growth rate was decreasing; The accumulative effects of industrial structure, economic scale, population size, energy structure, per capita income, urbanization level and industrial strength of urban residents played positive roles on greenhouse gas emissions, in which the contribution rate of industrial strength of urban residents reached 13.66%. The accumulative effects of energy intensity and agricultural production intensity played negative roles on greenhouse gas emissions, in which the contribution rate of agricultural production intensity was more than 50%. The research results indicate that the influence of industrial and agricultural activities is so significant that they can not be neglected. The paper would provide some references for Fujian province to formulate the policies and measures scientifically on energy-saving and emission reduction.

  Soil erosion is a common environmental problem in the world. Hengyang Basin, located in hilly region of South China, with a population of millions, plays an excellent role in social and economic development of Hunan Province. So, it is of practical significance to understand the soil erosion processes in the basin. This paper collects the following materials such as the landsat images of 2000 and 2008, precipitation data from 1959 to 2008, the 1/250 000 DEM data and Soil Taxomony map of Hengyang. With those materials, the paper uses the RUSLE equation to calculate the whole quantity of soil erosion of the Hengyang Basin in 2000 and 2008 with ArcGIS 9.2, and the parameters in the equation are calculated with the method used in domestic reports in recent years. According to our results, the soil erosion in the basin can be classified into five grades: light, mild, medium, severe, and most severe. The large-scale engineering construction is the main reason causing soil erosion in the Hengyang Basin. In recent years the soil erosion situation has been improved, but the ecological costruction and control of soil erosion still need to be strengthened.

  Lightning prevention is particularly important for the Wudangshan Mountains Scenic Region, which has been listed as a site of World Cultural and Natural Heritage. With the range of 1 km2 (1 km ×1 km) being the basic unit, the lightning frequency, polarity, intensity and other parameters in each unit from Jan. 1st, 2008 to Dec. 31st, 2011 are gained for the whole region. At the same time, the influences of geological features and the lightning environment and geographical environment of the Wudangshan Mountains on lightning activities are analyzed. The results show that: most of the lightning happens at T14-18 in June-August. The daily variation of lightning frequency is obvious in each area, the peak appears at T16:00, while the minimum value at T10-11. The lightning frequency increases with the increase of altitude, while the average lightning current intensity decreases in the mountainous areas. As a result, the correlation coefficient between the lightning density and the elevation is 0.834 56. The atmospheric circulation characteristics indicate that there are three main types of lightning storms in the Wudangshan Mountains: there are subtropical high of the northwest lightning type，upper-level trough lightning type and vortex lightning type, in which the northwest lightning type of the subtropical high dominates the area.

  One-hour traffic circle has a significant impact on regional economic development, urban planning and daily life of residents. However, almost all existing studies use Euclidean distance method to study the circle. That is a simple way which only can artificially, qualitatively and roughly express the one-hour traffic circle. To overcome those shortcomings, this paper presents the traffic circle of Guangzhou according to the complex road network system, and analyzes the traffic circle quantitatively and accurately. The results show that: 1) The one-hour traffic circle of Guangzhou covers the nine major cities in the Pearl River Delta, in which Foshan benefits the most; 2) The inter-city rail transit and express highway networks contribute the most to the formation of one-hour traffic circle; 3) The one-hour traffic circle of Guangzhou is delimitated in a range of 120 kilometers from the central district of the city since urban roads are not straight; 4) There are not many islands in the traffic circle because of developed transport network.

  At present, China is in a critical period of upgrading industrial structure and realizing the transformation of economic development patterns. As an important part of the tertiary industry, the logistics industry has a role of reducing the cost of economic operation effectively, improving operational efficiency and promoting the upgrade of industrial structure. In this paper the spatial dependency of rationalization of industrial structure and the optimization of industrial structure are tested, a spatial panel Durbin Model is built through introducing the spatial lag items of dependent variable and independent variable into the model. The impact of the development of logistics industry on the industrial structure optimization is analyzed from the aspects of rationalization of industrial structure and optimization of industrial structure, based on the thirty provinces panel data in China during 1997-2010. The results show that rationalization of industrial structure and optimization of industrial structure have significant positive spillover effect and there is an obvious difference among the eastern region, central region and western region of China. The development of modern logistics industry not only can significantly promote the process of the industrial structure optimization, but also promote the development of adjacent areas through the positive spillover effect. Finally, some relevant suggestions are put forward in this paper.

  Based on the urban panel data of 35 metropolitan cities from 1997 to 2011, the paper provides an empirical analysis on the long-term causal relationship between airport and city economic growth. The result shows that there is a unilateral Granger causal-effect from the growth of air passenger to the urban economic growth in the 35 major cities. There is a unilateral Granger causal-effect from the growth of air passenger and air cargo to the urban economic growth in the municipalities and sub-provincial cities. Hub airport is the endogenous factor to city economic growth, promoting the long-term growth. But there is a unilateral Granger causal-effect from the urban economic growth to the growth of air passenger in other capital cities, the small airports just have short-term effect. The discrepancy of airports will make us use the new-classic growth theory or endogenous growth theory to comprehend the meaning of urban economic growth, and will intensify the city economic differentiation. The development of aviation network will have important influence on urban system. The long-term causality from city economic growth to air transport is not common, possibly indicates that the industrial structure of Chinese metropolitan cities don’t have strong dependence on airfreight transport. Considering the conditions of city development, the airport city will be the new engine of the urban economic growth in the future, if the governments could plan airports and layout related industries reasonably.

  Based on the data from enterprises of textile and garment manufacturing from 1995 to 2012 in Shanghai, this paper explores the formation and evolution of the spatial pattern of textile and garment manufacturing in metropolitan areas by using methods of circle analysis, hot spot analysis and kernel density estimation. The results are as follows: First, enterprises are mainly located in the 10-30 km radius circle from city center, the suburbanization trend of enterprises is obvious and the hot zone transfers from central city areas and suburban areas to exurban areas. Second, the spatial distribution trend of enterprises of different nature and scale has its own features: foreign capital companies and joint venture enterprises are mainly located in suburban areas and their spatial location does not change obviously, the distribution intensity of domestic enterprises is significantly higher than that of joint ventures and foreign enterprises in the exurban areas; large enterprises are mainly located in northeast area of the city centre, as well as suburban areas and local centers with convenient traffic, mid-size enterprises are much stronger than large enterprises both on the range and intensity of distribution, the distribution density of small micro-enterprises in the exurban area is significantly higher than mid-size and large enterprises. Third, the results indicate that the factors such as history, change of geographical conditions, financial crisis, policy adjustment and planning guidance are the main driving factors.

  With the rapid economic development, resource and environmental pollution problems have gradually become serious, the limitedness of resources and importance of environment are gaining more and more public attention. The paper analyzes the relationship between economic development and coastal environment in Guangdong province during 1991-2011. An Environmental Kuznets Curve (EKC) econometric mode of the relationship between economic growth and waste water discharge in Guangdong was established. The results showed that: Fitting curves of Guangdong’s waste water emissions and GDP reflected significant EKC relation. A decoupling effect occurred between industrial wastewater emissions and GDP. Industrial production’s pressure on resources and the environment gradually reduced. Sewage emissions growth was relatively fast, leading to serious eutrophication of coastal waters. The frequency of occurrence of red-tide gradually increased, which had a direct threat to the normal functioning of the coastal water body. The annual change of coastal catch rate in Guangdong suggested that the biodiversity of the coastal waters was to a certain extent restored, but the situation was still not optimistic. The EKC theory shows that economic growth will ultimately improve the quality of the environment, but that has prerequisite. The province must develop environmental protection policy and establish coastal ecological conservation areas, so as to achieve regional economic development in harmony with the environment.

  The toponym culture of the Thirteen Hongs in ancient Guangzhou (Canton) is a spatio-temporal system. Although it’s now difficult to find the ancient buildings of the Thirteen Hongs on the ground, their relics still can be identified. There are many buildings closely related to the system, and so it’s possible to understand the beginning, development and change of the system and find relation between the environment around the relics and the sino-foreign trade by investigation on the toponym culture of Guangzhou Thirteen Hongs. The Thirteen Hongs should be highlighted as an international famous brand for Guangzhou, and a historical and cultural trading port tourism project be established, that would contribute to the construction of international cultural city of Guangzhou. The article sorts out a series of geographic names of Guangzhou Thirteen Hongs, analyzes their toponym culture characters, reveals their distribution rule (along the river and closed to the waters) and the spread of the culture. The article also puts forward some measures to protect the intangible culture heritage of the Thirteen Hongs toponym.

  The Zhuang is a typical rice planting nationality in China. Rice planting in the Zhuang area is characterized by its strong adaptation to the environment. In different geomorphic regions, the Zhuang people have been fully aware of the profound influence of natural geographical environment, climate and soil on rice planting. In order to adapt their planting to the natural geographical environment and achieve maximum production efficiency, the Zhuang people who live in mountain area always choose to plant Japonica rice which grows for a longer growth period and is cold-resistant and infertility-endurable, while those who live in river valley and hilly area always choose to plant indica rice which grows for a shorter period . In Karst mountain areas suffering from water deficiency and drought, the local Zhuang people usually plant upland rice. However, as the upland rice tastes poor and the relation between people and land is changing from comfortable to tight, the upland rice planting status is falling in Zhuang’s planting structure. In addition, the position of the rice used in Zhuang’s life also affects the selection and planting of rice varieties.

  The rising of Macao in the Middle and Later Periods of the Ming Dynasty was an inevitable outcome since the Ming Government carried out very special foreign trade policy, although Macao was selected by Portuguese occasionally after they went through many changes. The paper tries to explore as a very tiny area why Macao could become a very important port of transshipment in the east-west trade at that time based on the particular tribute trade in the Ming Dynasty, and specially focuses on the influence of Guangzhou and economic relations between Macao and Guangzhou. In addition, the study analyzes the similarities and differences of Macao, Guangzhou and Yuegang, which were the only three open ports in the Later Periods of the Ming Dynasty, from the perspective of national trade. It is believed that the rising of Macao was largely benefited from the restrictions of Tribute Trade Policy of the Ming Dynasty to private foreign trade and traditional port development. Furthermore, Guangzhou had advantage in national foreign trade but shortage in some port functions, that helped Macao to establish the biggest international trade framework in the world at that time to play a role equivalent to an outer port of Guangzhou.

  Hot springs were wildly used for sightseeing, ablution, health caring and other recreational activities in ancient China. On the basis of systematic survey of the related historical hot spring data, this paper analyses the composing elements, forms and characteristics of ancient hot spring tourism landscapes. The conclusions are as follows: The landscapes of ancient hot spring can be classified into two types including single scenery and composite scenery. The single scenery was small scale hot spring landscape unit, which was composed of springhead, spring water, motion state, color, and hot spring organism, while the composite scenery was a complex of hot spring water, rocks, buildings, and plants, which constituted an integrated beautiful landscape. Some particular hot spring landscapes became local famous scenic spots. In ancient China local people in a region often selected their famous scenic spots to form a group of scenes, known as the Eight Scenes, the Ten Scenes, or the Twelve Scenes, in which hot spring landscapes were usually included. Each scene was always named with a phrase of four Chinese characters, describing the beautiful scenery briefly and artistically, and so the region could be well known for its famous group of scenes. The study of ancient hot spring landscapes would give useful enlightenment to the development and construction of modern hot spring tourism.
