贵州省红枫湖流域溪流级别、景观背景与水质的关系

选择红枫湖上游的夏云镇流域,研究不同溪流级别与溪流水质的关系。浑浊度、铵态氮含量与溪流级别存在较为明显的关系,总的来看,随溪流级别增加,溪流水浑浊度及铵态氮含量增加。在空间上表现为自上游至下游水质快速下降。未来应在加大水质监测密度的基础上,定量研究区分不同土地利用方式对水质的影响程度,为有效控制面源污染和治理红枫湖水环境提供基础依据。

Relationship between Water Quality and Stream Grade,Landscape Background of Hongfeng Lake Watershed in Guizhou Province

Xiayun Township watershed in the upper reaches of Hongfeng Lake is selected to study the relationship between stream grade and water quality.Turbidity and ammonium nitrogen concentration are obviously related to the stream grade,generally speaking,are positively correlated,and the water quality is degrading from the upper reaches to the lower reaches.In the future,the influence of different land use types on the water quality should be fully analyzed on the basis of enhancing the water quality monitoring to provide supports for effectively controlling non-point source pollutions and treating the water environment of Hongfeng Lake.
