摘  要:
张掖市黑河湿地在维系黑河流域经济社会可持续发展和生态安全等方面有极其重要的作用。为了解黑河湿地的水质状况,分别在2011年6月和2012年6月采集了水样并对5项水质污染因子进行评价。同时,为克服层次分析法中人的主观性对水质评价的影响,用AHP模糊综合评价法来分析黑河湿地的水质情况。结果表明,黑河湿地的水质状况较差,属于地表水Ⅴ类水质,总氮是导致水质超标的主要污染物。

摘  要:
The Heihe wetland in Zhangye plays an important role to maintain social and economic sustainable development and ecological security. In order to get the information about its water quality,we collected water samples in June,2011 and2012 respectively,and analyzed five water pollution factors. The analytic hierarchy process(AHP) were used to analyze water quality to avoid the subjective effect by fuzzy comprehensive evaluation. The results indicated that the quality of Heihe wetland was worse and it belonged to the level of Ⅴ. The element of N was the major reason to cause the wetland deterioration.
