| 摘 要： | 以全国水环境数据库的监测记录为第一手资料,以各大流域片为单位,从宏观上介绍了各大流域片的水质总体概况,包括各类水质所占比例、污染水质的超标物类型等,基本反映了我国各大流域在20世纪90年代的水质状况以及水环境的时空变化特征.总的来说,我国的水环境状况不容乐观,水质污染比较严重,尤其是我国北方的流域片.

| Abstract: | A perfect water quality monitoring system has been built in China during 50 year's effort After many years,we have collected a great deal of water quality data.The China water environment information database was finished in 2001.It includes water quality testing records in 1990s of 160 important water quality stations.The database,maintenance system and in formation system based on Web GIS have made water quality data being shared.In this paper,the prime water quality situation of every big river area are analyzed based on these original data.The probable situation of water environment can be reflected by the statistics,such as water quality class and primary water pollution type.The results show that water environment situation of China is not optimistic,water pollution is serious,and the river area in North China such as Yellow River and Liaohe River are,especially,seriously polluted. |
