国土资源部下发《关于报国务院批准的土地开发用地审查报批工作有关问题的通知》

近日,国土资源部推出一个关于土地开发用地审查的规范性文件《关于报国务院批准的土地开发用地审查报批工作有关问题的通知》。《通知》指出,我国荒山、荒地、荒滩等土地后备资源多处于干旱、半干旱地区,生态环境脆弱,盲目开发将会造成土地风蚀沙化和水土流失现象,不仅影响土地资源可持续利用,还会破坏生态环境。因此,土地开发必须在改善生态环境。

STUDY ON ECOLOGICAL SPACE OF URBAN AGGLOMERATION-Taking Wuxi City as an Example

From the angle of ecology,urban agg lomeration presents relevant types of landscape structure,which in-clude Patch,Corridor and Matrix.There are different landscape feature s and different problems in differen t development phases.This paper has put forward fi ve basic conditions for security pattern of landscape ecology of urban agglomeration,described quantitatively the featu res for landscape ecology in Wuxi,an d analyzed ecological background of spatial expan-sion and spatial organization of urb an development in Wuxi.From the angle of ecological land use and non-ecological land use,the paper has analyzed the featu res of land use and ecological distribution of land in the urban area.The s patial mod-el of cities and towns in Wuxi is composed of one metropolis,two urban zones and three development axes.This th esis has planned preliminarily ecologic al protection network at four levels in the urban region according to four layers.At last,combining landscape ecology with ur ban space,a tentative security pattern of landscape ecology has been pla nned in Wux-i,namely Source-Buffer Zone and Metropolis,Radiating Routes and Expan sion Direction of City,Strategic Point and Interac-tion between Cities and Towns,Inter-Source Linkage-Corridor of a Stabl e Landscape Structure.

Study on land use changes of the coal mining area based on TM image

Based on the two temporal TM images of 1995 and 2001 of one coal mining area,analyzed the variety information of the coal mining area.Relative registration were done with the two images firstly,then cut out the study area for experimental data,classi- fied the coal mining area using supervised classification in ERDAS,the coal mining area will be divided into five categories as water body,agricultural land,construction land,coal mining area and other land.Make land use change matrix,the result shows that in the six years of 1995 to 2001,the change of the utilize of the land is greatly,the main represent is showed as follows: the area of water body,agricultural land and coal mining land had con- tinually increased,on the contrary,construction area and other decreased.The percen- tage speed of the construction land is the biggest,the value reach-1.08%.The main rea- sons is that with the exploitation of the coal mine and the reclaim of the land,the exploita- tion of the coal mining land make the agricultural land and construction area convert into coal mining land,on the other hand with the backfill of the subsided waterlogged land and the reclaim of the subsided land make the coal mining land convert into agricultural land.

Problems of Land Use and Management in Development Zones and Enlightenment to Implementation of "Construction up to the Mountains" Strategy in Yunnan

ln the research, problems of land use and management in development zone were concluded, and analysis was made on the causes in order to draw lessons from land use and management in development zones. Furthermore, enlight-enment to implementation of ＂construction up to the mountains＂ strategy in the ar-eas similar to Yunnan was explored, which provides references for developing of＂construction up to the mountains＂ strategy and protecting of highly-qualified cultivat-ed lands in dam regions.

ANALYSIS OF DRIVING FORCES ON THE CHANGE OF HISTORICAL FARMLAND USE IN SHANDONG PROVINCE DURING THE QING DYNASTY (1644-1911)

How land-cover has been changed by human use over the last 300 years is oneof the five overarching questions guiding the Land-use/Cover Change (LUCC) Science/Research Plan.China has variety of historical documents providing unique data superiority. So the characteristicsof farmland area in Shandong Province during the Qing Dynasty (1644-1911) are summarized firstly: 1)the rising trend of farmland area was striking; 2) farmland area had remarkable fluctuation; 3)farmland area per capita decreased dramatically; 4) wasteland reclamation index increased rapidly.Then, the driving forces of farmland area change are analyzed. It is concluded that natural andhuman factors are jointly influential. Among the driving forces, human dimensions are the mainfactors of farmland area change, which direct the general tendency of the changes mentioned above.And the natural factors influence the stability of farmland area as well. Variation of the naturalfactors would act as the major contributory factor to farmland area change during years or periodsof abrupt climatic changes, or during the intensive occurring periods of natural hazards. Besides,the passive aspects of human factors, such as war chaos also influenced the fluctuation of thefarmland area. This research indicates that it is feasible to study the land-use/cover change byChinese historical literatures, which has huge potential to provide a comprehensive picture of thegrowing dominance of human land-use and land-cover patterns that can be used in many global changeresearch projects.

FOREST LANDSCAPE PATTERN DYNAMICS OF LUONINGCOUNTY IN HENAN PROVINCE AND ITS DRIVING FORCES

With the help of ARC/INFOR and ERDAS software, based on the information from forest resources distribution maps and TM images, four indices were chosen to analyze spatial pattern changes of forest landscape of Luoning County, Henan Province from 1983 to 1999. The results showed that: 1) The number and total area of patches were rapidly increased with time changes. The fragmentation degree of the landscape was increasing greatly. 2) The area of some forest patch types, especially shrub forest, economic forest, Populus spp. forest, Quercus spp. forest, sparse forest, deserted grassland etc. had been greatly changed. 3) The fragemation degree of each forest patch type became greater from 1983 to 1999. 4) The transition probabilities of deserted forest, economic forest, Pi-nus tabulaeformis forest, Populus spp. forest exceed 85%,Robinia pseuoacacia forest, deserted grassland, 65% and Quercus spp. forest, non-forest, shrub forest had smaller ones, which were 26.5%, 29.1% and 45.3%, respectively. The main transition trends of various patches were non-forest and Quercus spp. forest. During the course of transition, the types that 50% of area was remained were Quercus spp. forest, non-forest and shrub forest. According to above analyses, the main driving forces, such as the management policies, market economy factors and influences of human activities etc. were brought out.

ANALYSIS ON THE PRESENT SITUATION AND CONTRIBUTING FACTORS OF VACANT COMMERCIAL HOUSING IN GUANGZHOU URBAN DISTRICT

According to the on-the-spot sampling investigation, this paper an alyzes the conditions of different districts, different locales and different ty pes of the vacant commercial housing as well as the contributing factors, which was completed in recent three years in Guangzhou urban district. It is found tha t vacant ratio of samples in Guangzhou accounted for 20.94%, which is relativel y high. The authors argue that real estate industry of Guangzhou has made rapid progress, at the same time, people should not overlook the vacant commercial hou sing. It will benefit the sustainable development of the real estate industry of Guangzhou to carry out effective measures and actively to make use of present v acant housing.
