摘　　要：根据京杭运河徐州段水污染的特点,建立了包括BOD_5、NH_3-N、酚和DO4项水质组分的多元耦合氧平衡水质模型及COD衰减经验模型。模型中的参数采用室内实验及优选结合的方法确定。基本方程的求解采用稳态解析解。同时,利用实际监测数据对参数和模型进行修正和检验。结果表明,模型结构合理,参数取值可靠,可作为大运河水质预测的实用工具及规划管理的依据。According to water pollution characteristics of Xuzhou reach of Grant Canal, to establish an oxygen equilibrium water quality model and COD attenuation model with BOD5, NH3-N, phenols and DO water quality components. The parameters of the models were determined by combining experimentation and optimization. The fundamental equation could solved by using 'stability analysis'. The parameters and model were verified and revised on the basis of monitoring data. The result showed that the model structure was reasonable and parameters were reliable, and may used as practical tool for predicting water quality and basis for program and management.
