The Land Use Change And The Driving Forces Of YILI River Valley

With the deepening of the research of global change, people pay more and more attention on the study of land use change, at present it has become a hot spot and one of the key problems in the study of geological research. The change of regional land usage and its driving force research also has become an important component of land use/land cover change research. In order to study the global land use/land cover changes, should launch a local or regional example of research. Accurate analysis regional land use change type, change speed and variations, find the driving factors of the land use change scientifically.This paper takes the downstream of West Tianshan river valley as the study area, using remote sensing and GIS technology to study the recent 18 years of the land use change information extraction and the dynamic analysis. In conjunction with the relevant social economic statistics, using the statistical method, the mathematical statistics, and adopt SPSS software to analyze the driving motives of the research.The main results were as follows:(1) The land use of the study area in 1990 to 2007 has changed very greatly, structurally cultivated land, grassland, forest land and unused land greater importance. The scale and speed of change perspective did not use the land, grassland, and cultivated land changes are more prominent. 18 years, land utilization degree rise, comprehensive land use potential study area is larger still.(2) The land use of the study area change by natural and human factors, For the humanistic driving force, population growth and economic development, agricultural production is the main land use change driving factor of the research area. Besides, policy is also an important factor caused the change of land use. Finally, according to the current situation of land use, the sustainable development Suggestions given to planning reasonable on the land use study area and use sustainable land for reference.
