根据 2 0 0 0年 10月 6～ 12日对乌苏里江虎头至饶河江段进行监测的结果 ,分析该水域水化学状况及生态环境得出 :该江段水环境状况较好 ,溶解氧、pH值及营养盐类适中。但水质已有变差的趋势 。

An investigation from Hutou to Raohe section of the Wusuli River was performed on October 6 to 12,2000.The results showed that the status of water made an excellent environment for fish to grow in the section.The DO,pH and content of nutritive salts were medium,but the water quality tended to be bad and the content of Cd went beyond water quality standard for fisheries.
