| 摘 要： | 采用综合营养状态指数法对仙溪湖水体富营养化状况进行评价,结果表明：仙溪湖目前已经处于轻度富营养-重度富营养状态,枯水期水体富营养化严重,水质最差,平水期次之,丰水期水质最好。从仙溪湖上游至下游水质有逐渐好转的趋势,氮、磷是仙溪湖水体富营养化的主要限制因子。最后,分析了仙溪湖水体富营养化成因,并提出一些防治对策和建议。

| Abstract: | The water eutrophication condition of Xianxi Lake is evaluated by using the comprehensive nutrition state index.The results show that Xianxi Lake is between slight and severe eutrophic state at present.Considering water eutrophication,the water quality in the high-flow period is better than that in the mean-flow period while it is the worst in the low-flow period.The water quality of Xianxi Lake changes gradually from a better to a worse state between the upstream and the down stream.Nitrogen and phosphorus... |
