    Yunnan is situated in the hub which links up Asia continent hinterland,South Asia sub-con tinent and Indo-China Peninsula.With the building of Guangtong-Dali Railway,which would be stretched over 800 kilometer to Myanmar,the China-Myanmar railway transport network would be formed.China will have convenient communication to the India Ocean.The China-Myanmar Railway would serve as a continental bridge and an international trade passageway from South-West China.Based on the comparative study of the projected southern,central and northern railway lines,by using the main object analysis,the southern line is suggested,which would be of the shortest line,the smallest project,the thrifteat investment,the lowest transport cost and the best economic benefit.As Stilwell highway,the traditional land passageway from southwest China to South Asia,deviates from the core region of the South Asia huge market,it is suggested opening up a new pas sageway from Yunnan,via Mandalny,Chittagong and Dahka to Calcutta on the basis of ChinaMyanmar Railway.

    Abstract ( )   PDF (688KB) ( )   Save

    Economic development and population agglomeration are two of the important indexes of determining urbanization,which not only depend on each other,but also impede mutually.GuangZhou's economy has developed rapidly since 1978,and the tendency of its population agglomeration and dispersion is people moving from the city proper to subordinate counies and from the old city proper to the new city proper.It shows that the continued and rapid economic develop ment would bring about the course of counter-urbanization in the extra-large city and urbanization in small cities which would in turn benefit the economic development.This urban system may give full play to the effect of key cities and to the superiority of regional resources.The necessity of forming the urban colony of Guangzhou is discussed in this paper.

    The old central business district (CBD) in Guangzhou,due to the impact of the long history,especially the centrally-planning economy before the reform was dominated by the commercial and residential functions.Under the new situation,CBD should develop rapidly,but it is very difficult to renew the old CBD due to various racoons.Since the reform of the economic system in 1978,Guangzhou,the central city,has set up the goal of becoming an international metropolis,which has resulted in the rapid expansion and economic growth of the city.These have promoted the construction and formation of the new CBD and caused dramatic differences between the old and the new CBDs in land use.For the horizontal dimension,the differences in building types and land use functions between the old and the new CBDs are analysed.For the vertical one,the differences in building heights,floor use type,commercial functions and function combination are identifed.As regards the comprehensive aspect,the differences in hight index,intensity index,land use structure of central business,and composition of commercial land use are recognized.The study has shown that the new CBD,compared with the old CBD,is close to the land use rule of the cities in western countries,namely with the distance increases from the CBD core number of central buildings decreases,central business activities weaken,and the ground floors are occupied by shops,etc.The differences in and use between the old and the new CBDs have implied that the location advantages have been recognized,the urban land use has been being realigned,and the urban economic activities are showing a restructuring tendency toward the dominance of tertiary sector and the spatial redistribution.During this transformation,several factors should be considered: e.g.the impact of economic globalization on the spatial.realignment of Guangzhou and the coordination among various function zones.

    The progress of city structure in terms of its schools,methodology and contents in the western countries during 1920-1980 are reviewed in this paper.The Period from the 1920s to the 1950s is the early times of city structrue study.The studies of the Chicago Schools about the residential variation in 1920 marked the beginning of city structure study.The studies from the 1950s to the 1960s are characterized by the use of complicated quantitative method in city structure.Social area analysis via ecological factor analysis was a typical example.Urban land-use study had extended to the variation winthin the same land-ues function,of which commercial land use gained a lot of attention.Another fundamental change was that some principles of neoclassic economy,especially the land economy and rent,were introduced to explain the city Strueture.During the period from the 1960s to the 1970s behavioral approach was raised.There were two main strands to this work.The first studied individual's decision-making process about location choice,and the second focused on the individual's perception to the world.The birth of institution.al approach was in the early 1970s,which argued that the inch determinant of location behavior is institution,particularly the economic power,and emphasized the study of housing market,power-holders in determining the urban socio-patterns and the class conflict,leading the study of city structure into a new stage.By the 1980s three types of work coexist within the current corps of city structure study.

    Karst areas make up about 37.8% of the total area of Guangxi,which are characterized by their deteriorated ecological environments with poor and thin soils,sparse vegetation,unevenly ditributed rainfall and short water resources.Meanwhile,the interior structure of agricultural ecosystem is unreasonable,the input of nutrition and energy is less than the output,and the irra.tional exploitation of natural resources results in further deteriorahon of ecological environmonts,the dislocation of ecological balance,the increase of natural dialers,and the decrease of the sta bility and continuity of agricultural ecosystem.Those have affected the development of agricultural production and national economy,and people's life and existance in Karst regions.It is neces sary to regulate reasonablly the structure of agricultural production,to develop forestry in line with local conditions,to enhance environmental protection and harnessing,to incrase the input of nutrition and energy in agricultUral ecosystem.The authors consider that the development of agriculture in the regions should presuppose the solution of food and clothing problems for the lo cal people and the coordination with market economy,and should follow the direction of eco-agri culture and stereo-agriculture in order to achieve both long term and short term benefits.
