| 摘 要： | 选用对植被状态表征较好的归一化植被指数(NDVI),在GIS和RS工具支持下, 选用多时相北京Landsat TM遥感影像,解译和分析出NDVI的时空变化特征,利用植被指数与植被覆盖度的关系及遥感测量法测算植被覆盖度.结果显示:北京市整体植被覆盖度呈增长趋势,市区植被覆盖度变化不大,部分区县植被覆盖度则由于城镇化推进而略有减少.

| Abstract: | The index NDVI which can reflect the state of the vegetation coverage well is selected to interpret and analyze the spatial change characteristics with multi-temporal landsat TM images and the support of GIS and RS.By means of relationship between of vegetation index and vegetation coverage,the method for remote sensing measurement is adopted to measure vegetation coverage.The result reveals that the total vegetation coverage in Beijing is increasing while it is little change in urban district,and slight de... |
