基于RS、GIS的松花江水域时空动态变化研究

Study on Songhua River Watershed Space-time Change Based on RS and GIS

以RS、GIS技术为支持,以松花江水域(哈尔滨市区段)2002年的SPOT4和1989的Landsat TM遥感数据为基础资料,结合RS和GIS的应用原理,分别运用ERDAS IMAGE和ArcGIS软件,实现对水体信息的提取分析,在此基础上,进行叠加分析和统计处理,揭示河流形态特征的时空变化,为水资源的利用和保护提供空间信息,对水域的资源管理和可持续发展具有重要意义。

Based on the RS and GIS , the study region of Songhua River of Harbin City was selected and the data of SPOT4（2002a）and Landsat TM（1989a） was used. According to the theory of RS and GIS, the software of ERDAS IMAGE and ArcGIS9. 0 was used to extract the water information. On this base, in order to discover the space-time change of water character, the water information of different periods was overlayed analysis and statistic analysis. The result could provide spatial information for use and protection of water resource, which provided the important sense for resource management and sustainable development of study region.
