Analysis And Stimulation Research On Akesu Region Land Use Trend By GIS

This paper, which origins from the study of the land-use trend analysis in Tarim River Watershed which is one sub-study of Water Distribution Management System of Tarim River Watershed that is national key project of the tenth five-year plan for progress, mainly studies the land-use change past 10 years in Akesu Region, Xinjiang Uigur Municipality.This study analyzes the classification map of land-use during the period of 1990~2000 by the method of polygon overlay, then gets one new data layer which includes synthetical attributes and getstransition matrix of the spatial analysis of land transition which reflects the extent, speed, trend index and regional difference using the new data layer. Also, Akesu Region land-use spatio-temporal evolvement is described well.Use the transition matrix of land-use and annual transition ratio to analyze the situation of land-use macroscopically by change trend. And the other method uses the cellular automata theory to construct GeoCA-LandUse model to describe the change on the real time. The study results have important reference to macro-control and practical use.The study results of land-use spatio-temporal evolvement in Akesu Region in this paper provide theory basis and methods for synthetical appraise on eco-environment and suitable layout of land-use, and in the future, put on more attention on the research, we will get better effect.
