摘要
水体质量是多因素影响的表现,水质评价是对水体质量多因素的综合评判,水质类型和分级标准存在模糊性,因而采用模糊数学方法对水质进行综合评判比较可行。介绍了水质评价的多级模糊综合评判方法及步骤,并应用到鄞州区内河水质评价,对铜盆浦、县中、梅墟、潘火4个断面不同时期的水质进行比较,综合评价整个内河水质,结果表明,鄞州区内河水质处于Ⅲ类与Ⅳ类之间,各断面丰水期水质较枯水期和平水期好,铜盆浦断面水质全年较好。
The water quality is representation of the impact of multi--factors, and the assessment of water quality is comprehensive evaluation of these factors. Since the water quality grade and its criterion are fuzzy, it is feasible to evaluate the water quality by the fuzzy mathematical method. This article introduces multilevel fuzzy comprehensive evaluation method and procedure as well as its application in urban river water quality evaluation in Yinzhou City. By comparison of the water quality in four spots in different seasons, the water quality is evaluated comprehensively. It provides a method of evaluation of water quality in urban rivers.
