摘要
本文在详细介绍水环境水质灰关联评价分析方法的基础上,对珠江流域支流邕江南宁市河段进行了水质评价。根据2004年与2005年邕江南宁市河段水质灰关联计算结果,该河段水体质量总体较好,但由于水文情势以及沿江工农业发展等原因,年内各月水质相差较为明显,2004年和2005年各月属于Ⅰ级水质的关联度分别为0.772 0～0.914 5和0.797 5～0.964 5。
The paper appraises the water quality of Yongjiang river in Nanning city river section of Zhujiang river basin of the basis of in troduction of water environment quality grey relation analysis. The water quality is good in the river section of Naning city according to grey relation analysis result at 2004 and 2005 year, but the water quality difference is evident in various moons. The relation degree of water quality in various moons of 2004 and 2005 year are differently 0.7720~0.9145 and 0.975~0.9645.
