摘要
澧河水质状况是南水北调中线工程河南省受水区配套工程10号口门线路选择的重要考虑因素;不同的水质评价方法,会得到不同评价结果。水环境系统是一个典型的、具有模糊性的灰色系统,灰色关联评价方法物理意义明确,计算简单,运用基于点到区间距离的灰色关联评价方法,利用澧河2008-2009年的水质监测资料,对澧河现状水质进行了评价;并将评价结果与其他方法进行对比,结果表明该方法能很好的适用于水质评价中,评价结果可为南水北调决策部门决策提供参考。
The water quality of Li River is an important consideration when selecting the route of Gate No. 10 of auxiliary project in Henan provincial intake area of South-to-north Water Diversion Middle Route. Different water quality evaluation methods will obtain different evaluation results. Water Environmental System is a typical and fuzzy gray system, while gray relation analysis method is simple and physically univocal. Therefore, an gray relation analysis method based on distance from point to area is adopted to evalu- ate the water quality in Li River based on the Monitoring data of 2008-2009. The comparison with existing varies of methods shows that this method is available and the result can provide scientific reference for the section of the route of Gate No. 10.
