摘　　要：融合遥感技术和地理信息系统技术,以遥感影像为主要信息源,结合外业实地调查,对绍兴市本级河道进行遥感普查,再利用地理信息系统技术获取绍兴市本级河道(越城区、袍江开发区、高新区)的基本情况、空间分布等信息。此次河道遥感普查以高分辨率遥感影像为数据源,采用遥感技术与实地调查相结合的方法,通过普查基本掌握了绍兴市本级河道的基本情况,并以Webgis信息系统的形式展示普查成果,为今后有效开展绍兴市本级河道管理工作提供了第一手基础数据。This paper carried out remote sensing survey of Shaoxing city level channels by integrating remote sensing technology and geographic information system technology,taking remote sensing image as the main information source,and combining with field survey.GIS technology was used to obtain basic situation,spatial distribution and other information of Shaoxing city level river,including Yuecheng zone,Paojiang development zone and Hi- tech zone. The river census adopted high resolution satellite imagery for data source,combined remote sensing technology with field survey method.This census basically grasped the general situation of Shaoxing city level river,and the census results were shown in the form of Webgis information system,providing the first- hand fundamental data for the effective management of Shaoxing city level river in the future.
