摘要
目前雪野水库水质监测与评价采用现场采样,实验室分析的人工方法,针对该方法不能反映水质指标在空间和时间上的分布状况问题,本文提出了基于Web GIS的水质信息系统设计方案。水质数据采集设备将采集到的水质信息利用移动网的GPRS无线网络可以及时发送到数据处理和监控中心,系统充分发挥GIS在水质评价中的优势,自动完成评价过程。评价结果可以生成水质污染专题图,直观显示水库水质的时空分布状况。Web GIS强大的空间分析与统计功能为水质信息管理的标准化、网络化、空间化提供了有效的工具。
The method of water quality monitoring and evaluation applied by XueYe reservoir is sampling in the scene and analyzing at the laboratory at present. But the method can＇ t reflect the space-time distributing of water quality indexes. In order to resolve this problem, a design project of water quality information system based on Web GIS is provided in this paper. Data collected by water quality data collection instruments is transmitted to data processing and monitoring center through GPRS wireless communication network of Mobile. Making use of advantage of GIS in water quality evaluation, the whole process of water quality evaluation is accomplished automatically, and water pollution ma Pcan be created from evaluation result, the distributing of water quality indexes on space and time is manifested obviously. Web GIS, with powerful function of spatial analysis and statistics, provides an effective tool for the standardization of water quality management.
