| 摘 要： | 以1979年和2005年的LandsatTM影像为数据源，在对其进行几何订正、大气和地形辐射校正的基础上，采用归一化植被指数和改进的像元二分模型，对北京市门头沟区的植被覆盖进行了动态遥感监测，结果表明该区植被覆盖总体上呈下降趋势。在此基础上结合研究区边界矢量文件和DEM数据，利用GIS技术和生态景观指标分析方法，定量分...

| Abstract: | In this paper,we chose two TM images of 1979 and 2005 as data source,based on normalized difference vegetation index and improved pixel binary model.After geometry revision,atmospheric correction and terrain revision with the aid of remote sensing technology,we calculated the vegetation coverage of Mentougou District,and dynamically monitored the vegetation cover changes of this district.The result shows that the vegetation coverage has a downward trend.Then we analyzed the temporal and spatial changes of t... |
