模糊综合评价模型在巴南区花溪河水质评价中的应用研究

摘要

以2011年花溪河南湖出口断面、石龙桥断面水质监测结果为例，构建了模糊数学综合评价模型评价花溪河水质，结果表明：南湖出口水质较好，总体水质达II类，2月份水质最好，为I类，影响水质的主要因子为高锰酸盐指数与溶解氧；中下游监测断面石龙桥评价结果均为V类，水质较差，主要污染因子为氨氮和总磷。评价结果与实际情况相符。%Taking the water quality of Nanhu section and Shilong section of Huaxi river in 2011 as example, this article sets up a fussy comprehensive evaluation model to evaluate the water quality of Hauxi river. The results show: the water quality of Nanhu belongs to class II, the water quality in February is the best which reaches class I, and the main factors affecting the water quality are permanganate index and dissolved oxygen ; the evaluation result of water quality of Shilong section belongs to class V, and the main factor affecting the water quality are ammonia nitrogen and total phosphorus. In summary, the evaluation results are consistent with the actual situation of water quality.
