摘要
研究土地利用/土地覆盖动态变化是研究全球变化的核心。文章以地理信息系统为研究手段,利用重心模型和时间序列动态模型对桃源县2000年～2009年的土地利用变化动态度及其重心进行了分析,得出耕地正在向东北方向扩展,园地向东南方向扩展,林地向东部偏南扩展,建设用地向西北方向扩展的结论,以期对桃源县的土地利用提供指导作用。
Dynamic study of Land-use is the core of global change studies.According to the geograhic information system as the research method,we use the distribution centre of gravity model and time series model to research the land-use change and the centre of gravity of Taoyuan Country from 2000 to 2009,getting the result that farmland is being extended to the Northeast,corner to the Southeast direction,forest land to the Southeast extension,construction land to the Northwest,with a view to provide a guiding role to the land use of Taoyuan County.
