东江上游支流水体高风险污染源解析
Analysis of High-Risk Pollution Sources from Water Body of Tributary in Upper Reaches of Dongjiang River
摘要
Abstract
It is of great significance to apportion sources of water pollution for the management of river basin environment.Monitoring data of surface water from 2014 to 2015 were obtained and pretreated.On the basis of zoning,principal component analysis (PCA) and multivariate linear regression (MLR) were applied to identify the spatial distribution of 8 variables and characteristics of their possible pollution sources in Gaopu River,a tributary of Dongjiang River.The results showed that pollution sources of District Ⅰ were principally agricultural non-point source pollution which accounted for 60.70％ of the total variance,followed by organic point source pollution.Distributed domestic discharge,mining and chemical industry pollution were identified as pollution sources for District Ⅱ.For District Ⅲ,point source pollution of nutrients,domestic wastewater and urban surface runoff accounted for 65.75％ of the total variance.According to the characteristics and differences of pollution sources,it's better to take targeted controlling measures for the improvement of river water environment.关键词
