摘　　要：构建了水质模糊综合评价模型,并应用于桂林市区的湖泊水质评价。结果表明,桂林市区湖泊水质达到Ⅰ类和Ⅳ类地表水质标准占的比例较大,基本达到了桂林市功能区划(Ⅳ类)水质标准,但是总氮、总磷含量较高。根据桂林市区湖泊水体污染的特点,建议采取一些措施:定期对桂林市区四湖进行疏导,针对水体中氮、磷的降解采取投加一定量的石灰石、沸石等方法,以保持桂林市区湖泊水质良好。The water quality of the lakes is an important tourist attraction in Guilin.To monitor water quality,Fuzzy comprehensive evaluation method is more comprehensive than the single-factor evaluation method.Fuzzy comprehensive evaluation model is used to evaluate water quality for Guilin lakes.The research shows that the water quality ofⅠ and Ⅳ,a large proportion,reaches the water quality standards for functional districts,but the content of nitrogen and phosphorus content is a bit high.According to the water pollution in Guilin lakes,it is necessary to take good measures such as regular dredging,and adding some zeolite and limestone into the lakes to reduce the content of nitrogen and phosphorus,so that Guilin lakes have a better water quality.
