Abstract: Protection of drinking water sources is a major issue critical to national economy and people's livelihood. Rapid and accurate determination of targets for ecological monitoring and informationization of on-site law enforcement are the keys to the monitoring of eco-environment of drinking water sources. Based on the high spatial resolution satellite data and the established drinking water source eco-environment monitoring and classification system, risk source information s of the drinking water sources were extracted from the satellite data and spatial location and accurate statistics of all the risk sources of the drinking water sources were realized. Furthermore, an on-site law enforcement system for eco-environment of water sources was developed with the aid of satellite data, lap tops, remote-sensing, geographic information technology, and GPS, realizing integration of rapid field data collection and map properties , and providing efficient technical measuresns for on-site monitoring of eco-environment of drinking water sources.
