Research On Sustainable Land Use Of Luding Country Based On Remote Sensing And Geographic Information System

Research on Sustainable Land Use has important meaning for our country. The research on county land is especially important to provide forceful foundation and development ideas to make full use of rural land resources. The application of GIS and RS technology make the analysis and evaluation more scientific and visualization, which are the powerful tools for nowadays land resources study.Because sustainable land use is the result of interaction of natural and economy and society, at first the research would analysis natural elements and economy elements and society elements of Luding country, and study land structure changes which effect by these elements, and analysis driving factors leading to these changes and land spatial distribution caused by these elements , so that to lay a foundation to make sustainable land use research more quantitative and more embodiment and more rationalization. Based on above analysis consequence, article evaluate the sustainability land use of Luding, use quantitative consequence to measure land sustainability degree, when evaluating the article using multiple time point integrated evaluation method, using analytic hierarchy process to determine weights, in the end the calculation results would be classified by several grades to measure land sustainability degree. Based on the conclusion by analyzing sustainable land use system and by evaluating land sustainability degree, the article analysis the obstacle factors of sustainable land use of Luding, and finally provide countermeasures to serve Luding land use work. In the process analyzing and evaluating the article merge combine with GIS technology and RS technology and make consequence more scientific and more accurate.The research results of article show that land sustainability degree of Luding increase year by year, but total score is relatively low and it still have a great development. The government of Luding should strengthen land management and exploit land use potentialities, and strengthen science and technology application, and plan regional economic development as a whole, and combined sustainable land use and economic sustainable development, so that promote economy development fast healthy and efficient .
