摘要
采用哈尔滨市环境监测中心站提供的例行监测断面BOD5、NH3-N、CODCr、TN、TP、高锰酸盐指数、石油类、DO八个水质指标监测数据,选取PCA法对2014年上半年冰封期(1、2月份)内松花江哈尔滨段的水质进行综合评价.水质综合评价结果表明:1月份第1主成分因子为石油类、高锰酸盐指数和NH3-N,第2主成分因子为CODCr和BOD5;2月份第1主成分因子为CODCr和BOD5,第2主成分因子为高锰酸盐指数、TP;阿什河口内和呼兰河口内污染比较严重,与研究流域内的实际排污情况相吻合.
The PCA Method and the monitoring water quality data provided by The Harbin MunicipalEnvironmental Monitoring Center including 8 indicators of those routine monitoring sections--NH2 - N,CODcr, TN, TP, Permanganate index , petroleum , DO were used to comprehensively evaluate the waterquality of Songhua River in Harbin during the frozen period of the first half of 2014 （ January and February）. Theresults of water quality evaluation show that 1 st principal component factors of January were petroleum,permanganate index and NH3 - N; the second principal component factors of January were CODcr andBOD5 ; 1 st principal component factors of February were CODcr and BOD5 ; the second principal componentfactors of February were permanganate index and TP; the pollution in Ashihe - Hulan River estuary andHulan River estuary were more serious which matched with the actual emissions in the studied area.
