Variable fuzzyset basedmodel forevaluation of reservoir water quality
摘要
Abstract
In accordance with the characteristics of reservoir water quality evaluation index,such as diversity,randomness and fuzzyness,a reservoir water quality evaluation model is established with the method of the variable fuzzy set by educing the weights of all the pollution factors with the method of pollution contribution rate on the basis of the fuzzy comprehensive evaluation.By taking Dalongtan Reservoir as a study case,five cross-sections of the rservoir are selected for the water quality evaluation and then compared with the evaluation results got from the improved method for the water quality index evaluation.The result shows that both the merits and defects which all the indexes values are subjected to are fully considered by the evaluation model,i.e.the final results those are subjected to all the levels are considered and,furthermore,all the pollution factors are weighted,thus the evaluation results are not only more reasonable,but also are more realistic.关键词
