摘要
系统阐述了灰色关联评价方法在地表水水质状况上的实践应用,并应用该方法对苏州河1996年、2004年及2005年白鹤、黄渡和华漕等6个监测断面的水质进行综合评价。评价结果表明,通过近10年来苏州河综合整治工程的有效实施,苏州河的水质有了明显的改善,各断面水质状况由1996年的V类或劣V水,到2004年和2005年基本提高到IV类或V类水质状况,且上下游水质差别逐渐缩小。
The paper systematically summarizes the application of Gray Correlation Evaluation Method in the evaluation of surface water quality with which the water quality in the year of 1996、2004 and 2005 supplied by six inspected section of Suzhou river is evaluated comprehensively. It is concluded by correlation matrix analysis for comprehensive quality evaluation of water body that through ten years＇ effective implement of repairing projects in Suzhou river, its water quality has improved a lot, in each section has become grade four or five in 2004～2005 from grade five or below five in 1996, and the distinction of water quality between upriver and downriver is less than before.
