黄河多泥沙水体水环境质量评价方法及其应用

Water Environmental Quality Assessment Method and Its Applicationon Sediment-laden Water of the Yellow River

黄河多泥沙水体中存在的泥沙及其对水环境造成的影响给河流水环境质量评价带来了一系列特有的问题和困难.鉴于泥沙对水质评价的突出影响,为了完整地反映河流水环境质量状况,以及有效地区分由泥沙带来的自然污染与由污染物排放引起的人为污染,提出了黄河多泥沙水体水环境质量评价应遵循的基本思想方法.作为算例,应用该思想方法进行了黄河孟花段水环境质量评价.

The sediment and its influence on water environment cause a series of problems and difficulties in the water environmental quality assessment for sediment-laden water of the Yellow River. In view of the influence of the sediment on water quality assessment, the basic theory of water environmental quality assessment for sediment-laden water of the Yellow River is put forward to completely reflect the pollution situation and validly distinguish between the natural pollution caused by the sediment and the artificial pollution produced by the discharge. An example of application to evaluate the water environmental quality of the Menghua section of the Yellow River is given.
