According to the dichotomy pixel Spatial Modeler modeling tool used to calculate the vegetation coverage in mining, use of non-supervised classification of vegetation coverage on the mining area classification, coloring, and finally come to mine the vegetation coverage in 1990-2000 category map, quantitative description of the Shanxi Province, 10 years of vegetation cover change: The region coverage to low, medium and high-based, the proportion remained almost unchanged, a significant increase in very low coverage, high coverage significantly decline.

The spatial autocorrelation coefficient and spatial regression model are widely applied spatial statistic techniques to explain the effects and distributions of spatial factors. This study identifies the major driving forces of the spatial neighborhood effect on land-use/land-cover change in Metropolitan Taipei.

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.
