辽河流域水环境因子对大型底栖动物的影响研究

以辽河为研究对象,对底层水环境物理化学指标和大型底栖动物的群落结构进行了综合分析,并分析了能影响辽河流域生态环境特征的水环境因子,研究结果表明,大型底栖动物在流域中通常会受到底层溶解氧、水中营养物、重金属、沉水植物、底质、水深等多种因素的影响。

Taking Liaohe River as the research object, the community structure of bottom water environment physical and chemical index and Macrobenthos were comprehensively analyzed, analysis the influence factors of water environment to ecological environment characteristics of Liaohe basin, after the results of the study show that： large benthic animals often affected by bottom water dissolved oxygen, nutrients, heavy metals, submerged plant the depth of the water, sediment, etc in a watershed.
