摘 要:为了评价辽宁省抚顺市平山水库退役后河道水体的水质状况和生态恢复进程,2018年3月、7月、10月分别在该河道的上游、中游、下游进行水质的监测与底栖动物的采集,统计分析了水体的理化指标和底栖动物的优势种。结果表明,根据底栖动物优势种及优势种比例判断,平山水库总体属于中度污染水体;根据BI指数计算得知,该水库上游均属于轻度-中度污染水体;根据Shannon-Wiener多样性指数的计算,平山水库总体属于中度-重度污染水体。对3种结果进行综合比较,得出平山水库水质属于中度污染水体。In order to evaluate the water quality and ecological restoration process of the river water body after the decommissioning of the Pingshan Reservoir in Fushun City,Liaoning Province,water quality monitoring and benthic animal collection were carried out in the upper,middle and lower reaches of the river in March,July and October 2018. Statistically analyzed the physical and chemical indicators of the water body and the dominant species of benthic animals. The results show that based on the dominant species of benthic animals and the proportion of dominant species,Pingshan Reservoir belongs to moderately polluted water bodies as a whole;according to the BI index calculation,the upper reaches of the reservoir belong to light-to-moderately polluted water bodies;according to the Shannon-Wiener diversity index calculations,Pingshan Reservoir belongs to moderateseverely polluted water bodies in general. A comprehensive comparison of the three results shows that the water quality of Pingshan Reservoir belongs to moderate polluted water.
