摘要
文章首在解析挠力河不同时段的主要污染物及其贡献率。本研究基于2021年挠力河水质数据,应用多元统计方法和绝对主成分-多元线性回归(APCS-MLR)模型评价了挠力河的水体质量健康状况,并解析可能的污染来源及其贡献率。结果显示,通过时间聚类,挠力河流域可分成旱季和雨季两个时段。通过多元线性回归确定内源对CODMn、NH3-N、TP的贡献率分别为36%、78%、68%;大气沉降对COD和TN的贡献率为55%和38%;农业面源对CODMn、COD和TN的贡献率分别为80%、56%和67%;生活来源对于NH3-N、TP的贡献率为97%、60%。挠力河旱季的主要污染源是内源和大气沉降,雨季是农业面源和生活源。
The objective of this study is to analyze the main pollutants and their contribution rates in different periods of the Naoli River.Based on the water quality data of the Naoli River in 2021,the multivariate statistical method and the absolute principal component-multiple linear regression(APCS-MLR)model were used to evaluate the water quality and health status of the Naoli River,and the possible pollution sources and their contribution rates were analyzed in this paper.The results showed that the Naoli River Basin could be divided into two periods:dry season and rainy season through time clustering.Multiple linear regression was used to determine that the contribution rates of endogenous to CODMn,NH3-N and TP were 36%,78%and 68%,respectively.The contribution rates of atmospheric deposition to COD and TN were 55%and 38%.The contribution rates of agricultural non-point sources to CODMn,COD and TN were 80%,56%and 67%,respectively.The contribution rates of living sources to NH3-N and TP were 97%and 60%.The main pollution sources of the Naoli River in the dry season are endogenous and atmospheric deposition,and the rainy season is the agricultural non-point source and living source.
