| 摘 要： | 根据长江口水体 2 0个站位的DO、ABS、Cl-、B、P、BOD5、NH4 N、TOC、Pb、Cu、Mn、CODCr、SS、Cr(VI)等指标的系统监测结果 ,采用因子分析法对引起长江河口上游来水水质变化的因素作出了综合判断。各种影响因素中海水入侵、支流进入、城市污水排放的成因率分别达到 6 2 .0、2 4 .9和 4 .8%。

| Abstract: | According to the monitoring data of DO,ABS,Cl -,B,P,BOD5,NH4 -N,TOC,Pb,Cu,Mn,CODCr,SS, Cr(VI) etc. in the 20 sampling stations of Changjiang Estuary, a comprehensive judge was made for the causes to affect water quality of Changjiang Estuary by the method of factor analysis. Seawater intruding, branch river entering and wastewater discharging composed the main factors with their contribution rates of 62.0%, 24.9%and 4.8%respectively. |
