| 摘 要： | 在充分理解水环境承载力概念的基础上，选取水环境承载力评价指标，确定分级评价标准，引入神经网络理论，构建了3层BP神经网络评价模型，并将其应用于山西省2004年、2010年水环境承载力评价；结果表明，山西省2004年、2010年水环境承载力处于弱承载状态；建立的评价模型结构简单、计算简便，具有很好的适用性。

| Abstract: | Based on the concept of water environmental carrying capacity and by selecting the evaluation index system of water environmental carrying capacity,establishing grade evaluation standard,and introducing neural network theory,it constructs the three-layers BP neural network evaluation model,and applies it to evaluate water environmental carrying capacity of ShanXi Province in 2004,2010.The calculations with the model shows that water environmental carrying capacity of ShanXi Province in 2004,2010 is still we... |
