Classification of water environment around highway in karst area with two-stage fuzzy synthetic judgment method with changing weight value
摘要
Abstract
In order to classify the water environment around highway,according to the gradation of the water enviromental factors and the fuzzy characteristics of the factors, a fuzzy mathematical method was uesd and a model of synthetic judgment on two-stage fuzzy of classification of water environment was established.Evaluation model adopted changing ranks to determine the values of degrees of membership for all the influence factors and adopted AHP to determine the basic weight value of all the influence factors and considerd the practical condition to deal with the basic weight values through changing weight value for all the influence factors, the calculation was realized by VB languages program, and the subjectivity of judgement and complexity of calculation were reduced, thereby, the results of evaluation can be more reasonable. The result of water environmental sensitivity classification of the 23th contract section of Yanling-Ruchen highway of Hunan indicates that the water environment of this contract section is part of moderate sensitive type, which just needs to take the reasonable protection measurements for the local water environment during the project construction. Appraisal conclusion and the results of field investigation are consistent,which validates this method is feasibility and reasonable.关键词
