摘要
选取了黑龙江流域黑河及同江两个重点断面,研究了其水环境状况,结果表明,2004-2005年,黑河江段高锰酸盐指数较高,同江江段氨氮浓度较高,地表径流将大量的有机质带入界河黑龙江是河流中高锰酸盐指数超标的主要原因.计算了2001—2005年松花江向界河黑龙江输入的高锰酸盐指数和氨氮年通量的大小,结果显示年通量的大小主要是由流量决定的.
Selecting the Heihe and Tongjiang sections which are the important sections of Heilong river, this paper studies on the water environmental condition, the result showed that, from 2004 to 2005, the permanganate index in the Heihe section is higher, the concentration of NHz--N in the Tongjiang section is higher. The massive organic matter in the surface runoff flowing into the river is the main reason that leading the permanganate index ex- ceeding the standard in the boundary river Heilong river. By calculating inflowing amount of permanganate index and NHz--N of Songhua river into Heilong river, it indicates that the annual flux is determined by current capacity.
