基于改进的模糊综合评价法的饮马河水质综合评价研究

根据饮马河2014年汛期七个断面的水质监测数据,采用改进的模糊综合评价方法,对饮马河水质进行了评价,并将评价结果与单因子评价方法、传统的模糊综合评价法进行了比较.结果表明:饮马河流域上游水质明显优于下游水质,其中,靠山屯断面处水质已达Ⅳ类水质标准,应着重进行治理.三种评价方法的对比结果表明:改进的模糊综合评价方法在保持与单因子、传统模糊综合评价法评价结果正相关的基础上,既避免了单因子水质评价方法对于水质过于片面评价的弊端,又克服了传统的模糊综合评价方法难以评价水质因子之间重要程度的缺点,得出的水质评价结果,体现了水体水质的变化情况,更切合实际情况.

Water Quality Evaluation of Yinma Riverby Improved Fuzzy Comprehensive Evaluation

The paper evaluated the water quality of Yinma River by fuzzy comprehensive evaluation with the weight correction factor, on the basis of data from 7 monitoring sections in the flood season of 2014, and made a comparison with single factor evaluation and conventional fuzzy comprehensive evaluation.The results suggested that the water quality of the upstream is much better than the downstream of Yinma River, the water quality of the Kao Shantun section is much worse,which needs much more remediation.The fuzzy comprehensive evaluation concluded consistent results with the single factor evaluation and conventional fuzzy comprehensive evaluation, avoiding the one-side evaluation of the single factor evaluation and the weight significance absence of the conventional fuzzy comprehensive evaluation, which demonstrates that the fuzzy comprehensive evaluation can always conclude the actual water quality and its alteration.
