摘要
为探究五排水库的水质状况,于2018年11月对库区19个点位采集的水样进行测定,采用主成分分析法对库区水体的污染程度进行定量化评价.分析结果显示库区水体总体水质均超过Ⅳ类水标准,Ⅳ类水和Ⅴ类水占比分别为89%和11%.影响库区水质的主要物质为氮磷和有机物,污染物主要来源于库区上游的排水、库区周边村落的生产生活污水及底泥释放.库区总体各点位受污染程度不同,与主成分综合得分排序的结果一致,分析结果具有一定可靠性和实用性.
In order to explore the water quality of the Wupai reservoirs,in November 2018,the water samples collected at 19 points in the reservoir area were measured,and the principal component analysis method was used to quantitatively evaluate the pollution degree of the reservoir area’s water bodies and analyze the impact on the reservoir area.The analysis results show that the overall water quality of the water bodies in the reservoir area exceeed the IV kind of water standard,and the proportions of IV and V kind of water are 89%and 11%,respectively.The main pollutants of water quality are nitrogen,phosphorus and organic compound.The pollutants mainly come from upstream of the reservoir,the production and domestic sewage of the surrounding villages of the reservoir,and the release of sediment.The pollution degree of each point in the reservoir area is different,which is consistent with the result of the principal component comprehensive score ranking,and the analysis result has certain reliability and practicability.
