| 摘 要： | 采用3种方法分析黑龙江省松花江流域高锰酸盐指数非点源污染的负荷。分析结果显示,非点源污染造成的松花江流域高锰酸盐指数负荷约为70%;松花江流域支流源头属于高高锰酸盐指数河段,本底值约为5mg/L,河流流经1000Km非点源污染会增加高锰酸盐指数约1mg/L;松花江流域河流中高锰酸盐指数含量高的主要原因是流域内土壤有机质含量高。

| Abstract: | 3 kinds calculation were used to analysis the contribution of non-point pollution to CODMn in Songhua river, about 70% of CODMn flux came from the non-point pollution. The background of CODMn in the head of some branch rivers was about 5mg/L, and with 1mg/L uprising of CODMn the river flows 1000 kilometer. The higher CODMn in the river was caused with the higher soil organic matter in the river basin. |
