摘　　要：为改善上海世界博览会园区河网水系的水质,建立综合考虑河道复杂形态、生态浮岛、河道底质释放污染等因素的河网水动力及水质模型,并利用世界博览会园区引、排水试验测定成果对模型进行验证。结果表明,两模型的计算值与实测值吻合较好,具有工程适用性,可用于模拟复杂河网水量和水质的变化。利用河网水动力和水质模型对河网常规污染、初期雨水污染、突发水污染和世界博览会泵闸故障4种情况下的调度方案进行数值模拟,并在此基础上提出适应小区域、多节点控制的潮汐河网水环境治理的应急水环境调控预案。In order to improve the water quality of the river network in the Shanghai World Expo Park, a hydrodynamic and water quality model, which comprehensively considers the effects of fiver morphology, ecological floating islands, and river sediment, was developed for the river network. The model was verified by field test data. The simulated results were shown to be in good agreement with the field test data, indicating that the model has an engineering applicability and can be used to simulate the changes of water volume and water quality in complex river networks. The model was used to numerically simulate four regulation schemes in the cases of river network conventional pollution, initial rainwater pollution, water pollution that occurs abruptly, and pump and sluice failures. Based on these simulations, the predetermined schemes were put forward for water environmental emergency regulation of muhi-node controlled tidal river networks applicable to small areas.
