Driving force analysis of land use change based on Logistic regression model in mining area

In order to investigate the evolution and driving mechanism of land use in mining area, land use change of Jiawang mining area in Xuzhou was analyzed based on the TM/ETM images in 1990, 2000 and 2008, using remote sensing, GIS and software SPSS. With the Logistic regression model, the driving factors of land use change were analyzed from economic, social and spatial distance factors. The results showed that the characteristics of land use change in the study area were that the cultivated land and forest land continuously decreased, constructive land and water body rapidly increased, and grassland slightly increased, which were in an unbalanced state overall. The analysis results of logistic regression model for cultivated land and forest land change indicated that the change of cultivated land in first period (1990-2000) was dominated by the factors of "distance to the nearest mining area" and "distance to the nearest rural settlement", and priority factors in the second period (2000-2008) were "distance to the nearest rural settlement", "farmer's population density", and "distance to the nearest road". Decrease of forest land was affected by "elevation" and "distance to the nearest mining area" from 2000 to 2008. These results provide an important guide for ecological and environmental conservation, optimal allocation and sustainable utilization of land resources in mining areas.
