河北省环保局在环境保护工作中，运用测绘技术加强监管，取得明显效果。

　　该省环保局建设的污染源监控中心，是国家污染减排重点建设项目，同时建成了河北省环境污染事件应急指挥决策系统。在监控中心，运用卫星定位技术，对污染源进行精确定位，在电子地图上标注其位置。同时用卫星遥感技术，通过通信线路与污染源自动监控设备的连接，实现对污染源主要污染物排放情况的在线、连续监测，并对污染治理设施运行情况实时监控。一旦发生环境污染紧急事件，启动在地理信息系统平台上建成的环境污染事件应急指挥系统，该系统电子地图上标有环境风险源、危险品存放地、应急人员设备分布、污染物扩散模型，接收卫星遥感影像，连接应急预案、应急案例等信息数据库。环境保护监测车上装有卫星定位系统，可即刻进行分析、统计，建立污染扩散模型，为应急指挥提供科学计算结果和决策技术支持。

Hebei Province Environmental Protection Agency in environmental protection work, the use of mapping technology to strengthen supervision and achieved remarkable results.

Environmental Protection Agency building in the province's pollution monitoring center is a national key construction projects, pollution reduction, environmental pollution incidents in Hebei Province at the same time built up an emergency command decision-making. In the monitoring center, using satellite positioning technology, pollution sources for accurate positioning on the electronic map marked their location. At the same time using satellite remote sensing technology, through the communication lines with the pollution control devices to connect automatically and realize the situation of pollution discharge line, continuous monitoring, and operation of pollution control facilities, real-time monitoring. The event of environmental emergencies, start in the geographic information system platform built emergency pollution incident command system, the system has an electronic map marked with the environmental risk sources, storage of dangerous goods, the emergency personnel, equipment distribution, pollutant dispersion model, receives satellite remote sensing images, connect contingency plans and emergency cases and other information databases. Environmental Monitoring vehicle equipped with a satellite positioning system can be analyzed immediately, statistics, and the establishment of pollution dispersion model for emergency command and to provide scientific results and decision support.
