摘　　要：水源地保护区勘界可为水源地规范化建设方案编制、最严格水资源管理实施、环保督查等提供重要的地理信息数据支撑。以重庆市丰都区弹子台水源地保护区勘界测量为实例,采用CQCORS进行特征点数据采集,结合高分辨率卫图影像,以EPS地理信息工作站为数据处理平台,对水源地保护区勘界数据进行校核、投影换算、影像纠正与匹配、数字化地形图成图。成图精度检验结果表明,该方法高效快速,满足测量精度,可为类似工程提供参考。Delimitation of water source protection zone provides important geographic information and data support for the formulation of standardized water source construction program,the strictest water resources management and environmental supervision.In the delimitation of Danzitai water source area in Fengdu District,Chongqing,we employed the CQCORS system to sampling feature points data,and by incorporating high resolution satellite images,we carried out data verification,projection conversion,image correcting and matching and digital topographic mapping via EPS geographic information work station.The accuracy test results show that the mapping method is of high efficiency,meets the desired measurement accuracy,which can provide reference for similar projects.
