| 摘 要： | 利用遥感和地理信息系统技术对1989,1995年的Landsat TM数据和2002年Landsat ETM＋三期遥感数据进行处理,反演和计算松花江流域的归一化植被指数（NDVI）,在此基础上,获取研究区域植被覆盖度。在ArcGIS9.2软件空间分析模块的支持下,对研究区域三期植被覆盖影像进行叠加分析,以流域尺度和栅格尺度分析植被覆盖变化的时间和空间特性,获取研究区域植被覆盖度空间格局分布特征,为该区域植被覆盖度的自动化监测提供很好的技术支持。

| Abstract: | Based on the Remote Sensing（RS） and Geographical Information System（GIS） technologies,the remote sensing image of Landsat TM in 1989 and 1995,and Landsat ETM＋ in 2002 of Songhuajiang watershed were used to retrieval and calculate the NDVI of study region.On this base,the vegetation coverage of Songhuajiang watershed was drawn.The vegetation coverage of three periods images were analyzed using the method of overlay assisted by the spatial analysis model of ArcGIS 9.2.Then based on the scale of watershed and grid,the spatial-time changes characters of vegetation coverage was analyzed,which obtained the spatial pattern distribution characters of vegetation coverage in study region.It provided the technical support for automatic and dynamic monitoring the vegetation coverage of Songhuajiang watershed. |
