松花江流域植被覆盖动态监测遥感分析——哈尔滨市区段为例

Analysis and Dynamic Monitoring of Vegetation Coverage by Using Remote Sensing in Songhua River Watershed—— Harbin Region as Example

利用遥感和地理信息系统技术对1989和1995年的Landsat TM遥感数据进行处理,定量反演归一化植被指数(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,对研究区域植被覆盖进行叠加分析,揭示区域植被盖度的数量变化和空间变化特征,对土地资源管理和可持续发展决策及生态环境保护有科学指导意义。

Based on the RS and GIS,the Landsat TM image of 1989 and 1995 was deal with,the NDVI of study region was quantitatively inversed.On this base,the vegetation coverage was obtained,with the support of ArcGIS 9.2,the vegetation coverage of study region was overlayed,which could reveal the quantity change and spatial change characteristics.The study results could provide the policy for land use,sustainable development and environment protection of study region.
