准确快速地确定生态监察目标,以信息化的手段辅助现场执法以提高现场环境执法效能,是饮用水源地生态环境监察的关键.基于高空间分辨率卫星数据,在构建饮用水源地生态环境监察分类体系的基础上,实现了利用卫星数据提取水源保护区的风险源信息,并对水源地所有风险源实现空间定位和准确统计.基于卫星数据和平板电脑,结合遥感技术、地理信息技术和定位技术,开发了水源地保护区现场执法系统,实现了现场数据的快速采集和“图属”一体化的业务集成,该系统可为水源地生态环境现场监察提供有利的技术手段.
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 environmental 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 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 measures for on-site monitoring of eco-environment of drinking water sources.
