基于WebGIS的松花江哈尔滨段水质监测与评价系统

A WebGIS based water quality monitoring and evaluation system for the Harbin section of Songhua River

研究了松花江水质的监测与评价。针对松花江哈尔滨段点源众多、面源分散,水环境复杂,造成全面、快速获取流域水环境信息及准确评价流域水环境困难,影响了松花江流域大尺度综合水环境管理的问题,构建了基于网络地理信息系统(WebGIS)的松花江哈尔滨段水质监测与评价系统。该系统运用了WebGIS技术和水污染指数评价方法,能够快速全面地获取水质断面监测数据并快速进行水质评价,同时将评价结果结合GIS技术实现可视化、专题化表达,为水污染治理相关部门对水质监管控制、宏观调控、污染治理与规划提供科学依据和决策参考。

The water quality monitoring and evaluation for the Songhua River were studied. In view of the situation that in the basin of the Harbin Songhua River,there exist difficulties in fast,comprehensive collection of the complex water environment information and fast,accurate evaluation of the information caused by numerous point sources,disperse area soures and complex water sources,disperse area soures and complex water environments,a water quality monitoring and evaluation system for the Harbin section of the Songhua River was constructed. The WebGIS technique and the water pollution index assessment method are applied to this system for fast and comprehensive acquirement of the monitored data in the section of water quality and fast water quality evatuation. At the same time the evaluation results combined with GIS technology can realize visualization,project presentation. It can provide scientific basis and decision-making reference for the relevant departments of pollution control to make supervision control,macro-control and pollution control and planning.
