基于改进模糊层次分析法的龙华港水系水质综合评价

采用改进的模糊层次分析法，构建水质评价模型，分别对龙华港水系10条河道的13个断面2011年4月（非汛期）和8月（汛期）两个时段的水质监测数据进行评价。结果表明：大部分河流水质达标，汛期水质好于非汛期；评价结果与运用传统方法得到的评价结果基本吻合，并能反映出同一级别下不同断面的水质优劣情况，与实际情况相符合。

Comprehensive evaluation of water quality of Longhuagang River system based on improved fuzzy analytic hierarchy process

The improved fuzzy analytic hierarchy process method was used to build a water quality evaluation model, which was applied to the evaluation of water quality monitoring data from 13 sections of ten rivers in the Longhuagang River system in April （the non-flood season） and August （the flood season） of 2011. The results show that the water quality met the standard in most areas, and it was better in the flood season than in the non- flood season. The evaluation results were basically consistent with the results obtained using the traditional method and can better reflect the status of water quality at different cross-sections of the same level, being consistent with the actual situation.
