| 摘 要： | 基于2010年3~7月的现场监测数据，采用主成分分析和绝对主成分得分/多元线性回归方法定量解析了东江东莞段取水口水质的季节性污染源。结果表明，三个主成分F1、F2、F3反映了83.85%的原始信息量，F1代表的污染源具有与东引运河相同的污染物特征；由运河排涝时对应的样品数据计算表明，运河排涝即为F1所代表的污染源；通过分析污染源贡献率，获得受运河排涝影响最为显著的指标为氨氮、总磷，其次为高锰酸盐指数、总氮、总有机碳。可见运河排涝是引起下游取水口水质季节性恶化的主要原因。

| Abstract: | Based on 5-month consecutive in-situ monitoring data in 2010, the principle component analysis (PCA) and absolute principal component score/multiple linear regression (APCS-MLR) are applied to analyze the seasonal pollution source of water intake on Dongguan reach of Dongjiang river. The calculated result shows that three principal components F1, F2, F3 include 83.85% of the original information; the characteristics of pollution source F1 is the same as the one of Dongyin Canal pollutants; F1 scores of the sample data are significantly higher during canal drainage, and the canal drainage is F1 representing the source of pollution. Through the analysis of the sources of pollution contribution rate, it indicates that most significantly affected by canal drainage indicators are NH+4-N and TP, followed by TOC, TN and CODMn. Thus, canal drainage is the main factor to cause the seasonal deterioration of downstream water intake water in Dongjiang river. |
