双模型综合评价牛尾岭水库水质

Double model comprehensive evaluation of water quality in Niuweiling Reservoir

为全面掌握北海市牛尾岭水库水质情况,根据综合水质标识指数法和综合营养状态指数法的评定标准,分别对北海市牛尾岭水库的水质状况和富营养状态进行全面、系统地评价。结果显示牛尾岭水库水质达到GB3838—2002《地表水环境质量标准》II类标准,但水体不稳定,有向III类水质变化的趋势;水库水质总体处于轻度富营养状态,但在丰水期富营养化会加重。

In order to master the water quality of the niuwei ling reservoir in beihai city, the water quality status and the eutrophic status of niuwei ling reservoir in beihai city were systematically evaluated and analyzed by comprehensive water quality index method and comprehensive nutritional status index method in this paper. The results showed that the water quality of the oxtail reservoir reached the Standard of Surface Water Environmental Quality（GB3838—2002） class II, but the water was unstable, there was a tendency to change the water quality to class III.The water quality is generally mild,but the eutrophication will be increased during the period.
