2013年3月至2014年2月,以上海市6条中小型河道为研究对象,选择pH、WT、DO、SD、NH4+-N、TN、DP、TP、CODCr、CODMn、BOD5、TOC和Chl-a作为水质评价因子,分别采用主成分分析法、综合污染指数法、综合营养状态指数法、有机污染指数法和综合水质标识指数法评价河道水环境质量,并对各评价方法和污染源进行分析.结果表明,6条河道水环境质量的空间差异性较大,其中淡江河污染最严重,工业河次之,丽娃河水质最好.TN和TP是6条河道水环境的主要污染因子.6条河道中的磷均以溶解性磷酸盐为主,工业河、长浜河、真如港和淡江河中的氮以氨氮为主,樱桃河和丽娃河以硝酸盐氮为主.
The parameters of water quality such as pH, WT, DO, SD, NH4+-N,TN,DP,TP,CODCr,CODMn,BOD5,TOC和Chl-a were chosen as primary assessment factors to evaluate the water quality of six medium and small creeks in Shanghai by principal component analysis, comprehensive pollution index, comprehensive nutritive index, organic pollution index and comprehensive water quality identification index from Match 2013 to February 2014. The evaluation methods were compared, and pollution sources of creeks were also analyzed. Results showed that great spatial difference was obtained among the water qualities of six creeks. The water quality of Danjiang creek was the worst, followed by Gongye creek, and that of Liwa creek was the best. TN and TP were the main primary pollution factors. The major form of total phosphorus in the six creeks was existed as dissolved phosphorus. The main form of nitrogen in creeks of Gongye, Changbang, Zhenru and Danjiang was of ammonia nitrogen. However, nitrate nitrogen was considered as the main form of nitrogen in creeks of Yingtao and Liwa.
