The Analysis Of Structure Of Landscape Of Land Use In Beibei Based On GIS

The land is the foundation of human life,but also the most remote sensing image directly reflects the environment information,and remote sensing technique can achieve high precision of current land use and land cover drawing.Land-use and land change (LUCC) is not only the global change,but also the results of global change.Land use and land change data acquisition is the important foundation LUCC research work. Along with the rapid development of remote sensing technology,it is the indispensable that to get the information from the remote image of subject information in research of the land use and land coverage.The change of the large scale district have had effective on some areas and district environment(landscape),while the human change the some areas land coverage,landscape structure by many manner of land use.It is one of the important reason of the whole world environment change that the human make use of the land in the field of land use and land coverage,then proceed to the next step that making the large scale district change.So the analysis for some areas of landscape structure is help to the research of the large scale district change.Taking Beibei in Chongqing for example,to use the remote sensing images in the year of 1995,2000 and 2006,by using remote sensing and GIS spatial analysis method, from the time sequence and space sequence analysis of Beibei,in order to analyze land use date changeable process and the spatial pattem of the characteristic matrix,this paper is to be probe into the law of the change of various types of current land use types space-time and quantity.We analyze the landscape index and the influence for land use diversity with the urbanization by using the landscape software for various types of FRAGSTATS 3.3.The research shows that:the data of quantity scale,the current land use types have had great changes in the land use especially in the land for construction and the tillable, in the period from the year of 1995 to 2000 the area percentage the type of land use is:construction land＞grassland＞forest land＞cultivated land＞unused cultivated≥territorial waters,in the period from the year of 1995 to 2000 the area percentage the type of land use is:forest＞construction land＞cultivated land＞grassland＞unused cultivated≥territorial waters.Due to interfering by human activity,the landscape structure develop to tendency of fragmentation in the 11 years in Beibei,to choose the range change index is to remarkable index for Beibei,the type of Mean Shape Index(MSI),Area-Weighted Mean Shape Index(AWMSI),Area-Weighted Mean Patch Fractal Dimension (AWMPFD) and so on,by the cardinal number of data of 1995,the law is to show that land use change with urbanization by timing:(1)In the year 1995,in the whole district of BeiBei,cultivation sight played a leading role,taking up 68%of the whole research area.Dry land sight had a high status, showing its own advantages.Woodland distributed along the border of Beibei and Jinyun Mountain mainly,patch distributes together,constructive land distributes in the synclinal layer and Jialingjiang River construction patch distributed together, constructive land distributes in the synclinal layer and Jialing River(2)The regional distributing pattern of the year 2000 was characteristically similar with that of the year 1995.In addition to all of these,construction land extended itself to the suburbs.The sight spot showed that the area was expanding.By the end of 2000,the construction had stopped expanding,while the suburb area was expanding.With the rational layout,the spot are now comparatively of equal size,only with the brims interrupted by people.As a result,the differentiation coefficient begins monishing. Industry gardens have also been built,such as San Xikou Industry Garden,Tong Jiaxi Tong Xing Industry Garden(A District),etc.(3)In the process of urbanization in the year 2006,the land use was on the increase, while the cultivation land was on the decrease.On the whole,the transformation from the agriculture sight leaded region into town sight leaded region has been completed, and cultivation land sight has been transformed into construction land sight,Patch density increased,area-weighted mean shape index multiply rapidly,the shape of patch came to complicated,appearing the irregular condition,and last getting the good advancing situation in Beibei.
