摘要：The comprehensive evaluation of the monitoring data of surface water in Handan City, based on the modelof fuzzy comprehensive evaluation, was made in this paper. According to the monitoring data, selectingseven evaluation factors, namely, permanganate index, BOD, total nitrogen, total phosphorus, ammonia,fluoride and dissolved oxygen, weight matrix has been established for each factor, and the weight of eachfactor was obtained in the assessment of water quality. Then using the membership function in fuzzymathematics, computed the data measured, and obtained the corresponding water level. The result of theevaluation shows that the water quality of Handan city is V level, severely polluted, and it becomes a securityrisk to the residents’ drinking water.
