Study On Yun County Land Use Change And Driving Forces Anylysis Based On RS And GIS

The researches on land use and driving forces is the frontier of geo-science, And the study of the region land exploitation by dynamic monitoring has become a significant part of it. In china, it is almost20years since we applied RS and GIS to monitor the land exploitation. The purpose of dynamic monitoring includes mainly the following two aspects:on one hand, utilizing remote sensing image to monitor the dynamic change of land exploitation. On the other hand, utilizing the data to analyze the transformation process and tendency that affect land exploitation, providing favorable basis for the anticipation of the land exploitation tendency.In this essay, The author take Yun County in Hubei province for example and use the Quantitative Research Method and the Qualitative Research Method to study the land exploitation and thrust in Yun County, and put forward a solution to the sustainable exploitation of land, which not only provides basis for the land resources exploitation of the region reasonably, but also provides reference for the other regions in our country. In the process, I utilize the Landsat TM image data about land resources satellite in2000, the second time land exploitation status quo in2008and the overall program of the national land exploitation. Besides, I combine the comprehensive factors in economy, society and environment that influence the transformation of land exploitation. Moreover, I adopt the ways of the SPSS, Mathematics Analysis, the Main component Analysis, Diverse Space-time sequence, and Markov Chain Analysis.At the beginning of this essay, the author firstly introduces the domestic and international status Quo and developing tendency of it, then illustrates the background and meaning of the research, introduces the software, mathematics method and mathematical models used in the study, and narrate the natural and social profile in Yun County on the basis of statisitical materials in different periods of it. In the end, the essay emphasizes the structure and traits of land exploitation in Yun County. From microscopic to macroscopic, from lateral to vertical, the essay, in space and time, indicates the spreading traits and developing rhythm of the land resource quantity and quality in Yun County. The results present that the transformation of land exploitation in Yun County is not only affected by the natural environment, but also influenced by social political factors, such as the quality of population, economy, urbanlization process and government policies. And the latter is gradually becoming the main factor. On the basis of it. I also use Main Component Analysis to analyize the thrust which affects the transformation of the land exploitation. And I come up with the problems of land exploitation in Yun County and discuss the ways to how to realize sustainable development.
