基于TM影像的县级土地利用动态监测

以1988、2000、2008年TM遥感影像为数据源,利用GIS技术,获得高淳县土地利用动态变化。结果表明,20年间耕地面积明显减少,水域和建设用地大幅增加,而面积的增加主要是通过占用耕地来实现平衡的。城镇人口和经济的快速增长,产业结构的调整优化和城镇规划变革促进了高淳县土地利用变化。

Dynamic Monitoring of Land Use Change in County Level Based on TM Images

Applying 1988,2000 and 2008 Landsat TM images as data sources, land use dynamic change in Gaochun County were obtained by using GIS. The result shows that the cultivated land decreased obviously. The waters and construction land increased substantially. But the area increased mainly through the occupation of arable land to achieve balance. The urban population growth, the economic development, the optimization of the industrial structure adjustment and the urban planning changes have promoted the land use change.
