【摘要】 在水环境质量的评价过程中,通常涉及到大量的复杂现象和多种因素的相互作用,评价中存在大量的模糊现象和模糊概念.介绍了模糊综合评价法的原理及其评价方法,同时将人工神经网络引入模糊综合评价隶属矩阵的确定过程,利用人工神经网络构造隶属函数矩阵,并以青岛大沽河为例,利用模糊综合评价法对其水质进行了评价,并取得了良好的评价效果.更多还原

【Abstract】 It is known that plenty of fuzzy phenomena and fuzzy concept in water quality evaluation are involved with a great many of complicated phenomena and interaction of multi-factors.The theory and means of fuzzy comprehensive evaluation is introduced in the article,and Artificial Neural Network,which can simulate complex non-linear function mapping without subjective feelings,is introduced into the decision of membership grade(MG) matrix and adopted to decide MG matrix.This method is applied in water quality evaluation of Dagu River and produces good evaluation effect.更多还原
