基于熵权－正态云模型的地下水水质综合评价
Water Quality Evaluation Based on Entropy Weight-Normal Cloud Model
摘要
Abstract
A model based on normal cloud model and entropy weight method had been established to forecast groundwater quality grade. Nine factors were chosen as the assessment indicators for the grade evaluation, including the fluoride, the permanganate index, the ammonia nitrogen, the chloride, the total hardness, the nitrite, the sulfate, the nitrate and the total dissolved solids. Parameters of the cloud model and evaluation grade were calculated with the chosen assessment indicators, which generated the normal cloud droplets and then the indicator weight had been calculated based on entropy weight method, finally, the comprehensive membership had been calculated and the water quality grade was given. The proposed model is validated with a series samples, comparative studies with fuzzy matter element model and projection pursuit model show that the entropy cloud model is effective and intuitive, which provides a new way of water quality assessment.关键词
