摘　　要：通过讨论环境质量变化的非线性行为 ,尝试建立起单项污染物的环境污染损失机理性模型 ,对之求解得到Logistic方程形式的环境污染损失数学模型 .将这种污染损失程度用污染损失率的形式表示出来 ,依据多项污染物共同作用机理 。Through discussion on non-linear action of environment quality variation, the mechanism model of pollution loss caused by single contaminant was constructed. The Logistic equation E LR =11+ β exp(- γC )is obtained through the solution of model, and it can describe the variation of environment pollution loss. According to mutual effect mechanism of multinomial contaminants, the integrated model of environment pollution loss ratio is obtained.Furthermore, the model is applied to environment quality assessment. The non\|linear assessment model is better to reflect loss situation of environment quality, and its assessment result is closer to the real situation and easy to understand.
