摘要
为探究滦河流域大型底栖动物群落结构特征及其影响因素,本研究于2020年和2021年的9月分别对其进行样品采集及水质监测,分析大型底栖动物群落结构特征,并进行水质评价。结果表明:滦河干流大型底栖动物群落结构空间差异明显,优势物种以昆虫纲种类最多;2020年滦河水质评价以清洁和经度污染为主,2021年以一般和重度污染为主,水质污染主要集中在上游和下游河段。
In order to explore the characteristics of macrobenthic community structure and its influencing factors in the Luanhe River Basin,samples were collected and water quality was monitored in September 2020 and 2021,respectively,to analyze the characteristics of macrobenthic community structure and evaluate the water quality.The results showed that the community structure of macrobenthos in the Luanhe River was significantly different,and the dominant species were insecta.In 2020,the Luanhe River water quality assessment was mainly clean and longitudinal-polluted.In 2021,the Luanhe River water quality assessment was mainly clean and longitudinal-polluted.The pollution was mainly concentrated in the upper and lower reaches of the Luanhe River.
