摘　　要：根据南水北调中线工程输水干线上不同断面的水质自动监测信息为该工程水质变化提供直接的信息,对输水干线的水质现状及变化趋势适时给出相应级别的预警信息,以便下游地区能够及时产生预案和采取必要的应急措施。水质趋势变化是一种高度的非线性过程,根据南水北调中线工程输水干线水质监测系统网络规划的结果提出了利用上游水质预测下游水质和利用当前水质预测未来水质的人工神经网络水质预测模型。This research will use water quality information in different monitoring sites to provide direct information of water quality change for middle route of water transfer project from South to North, a certain level of warning information on water quality status and changing trend will be put forward. So in the lower reaches of the route the prevention counterplan can be formed and certain emergency measures will be taken. Water quality change is a highly non-linear process, so an artificial neural networks water quality prediction model is put forwards to forecast the water quality in the future and in the lower reaches of the route based on the current water quality information.
