DYNAMIC CHANGE OF FOREST LAND AND GRASSLAND BASED ON RS AND GIS
遥感与GIS支持下的中国森林植被动态变化分析

The research of land use and land cover change is one of focus points for study on the global changes. And the research of dynamic change of forestland and grassland is significantly important for better understanding land use/land cover change and environmental management for sustainable development. In order to study the dynamic changes of forestland and grassland in China during the past five years, the technologies of Remote Sensing and Geographical Information System are used to analyze the spatial and temporal dynamical features of forestland and grassland. Furthermore, the mathematical methodology for study on forestland/grassland change is explored and developed. This research focused on the dynamical analysis of spatial temporal change of forestland and grassland of China in five years. At the same time, the mechanism of forestland and grassland change and its driving forces were discussed in this paper.
