Study on the driving forces of land use/cover temporal-spatial change. On the basis of the systematical study on natural and social-ecomic factors including climate, population, technology and affluence status etc. during the past 50 years in this area, the multivariate statistics simulation models of LUCC were developed for two periods of 1950's-1980's and 1986-2000 respectively. Then, the Thiesson polygon method was used to the spatial allocation of soci-economic factors, thereby the spatial relationship between land use degree change and socieconomic factor variation was detected within GIS. Based on the analysis of the integrative characters in different geographical divisions, the electivity index was employed to describe the possible impacts of the natural landscape structure on spatial differentiation of land use transition. At last, correlation analysis between major roads and the distribution of land use change was made.
