淮河洪汝河流域“多水源—多用户”供水联合调度模型研究及应用

Research and application of“multi-source,multiuser”water supply joint dispatching model in Hongruhe River Basin

以洪汝河流域为研究对象,基于水库、河道、地下水、区域地表水及其他水资源5类供水水源与12个需水区、县单元的“多水源—多用户”的水资源配置方案,构建系统模拟模型,并进行可视化软件开发。模型采用流域内1997年1月至2006年12月实测降雨资料计算的分区来水成果和通过需水预测得到的2030年水平需水量进行模拟计算,通过供水保障程度等计算结果评价模拟模型和水资源配置方案的合理性,另外软件通过可调节参数的设定增加模型的适应性。结果验证表明,本模型对于研究洪汝河流域区域水资源供、需平衡关系及既有水资源配置方案的合理性,以及模拟预测各年型区域水资源配置保障程度有很好的效果。

In this paper,the Hongruhe River Basin is taken as the research object.Based on five water supply sources:reservoir,river,groundwater,local surface water and other water resources and the"multi-source multiuser" water resource allocation scheme of 12 water demand districts and counties,the system simulation model is constructed and the visualization software is developed.The model uses the rainfall data from January 1997 to De⁃cember 2006 in the basin and the water demand in 2030 from the water demand forecast to simulate the model.The rationality of the simulation model and the water resource allocation scheme are evaluated by the calculation results of the water supply guarantee degree.In addition,the adaptability of the model is increased by the setting of adjustable parameters.The results show that the model has a good effect on the study of the relationship be⁃tween supply and demand of water resources and the rationality of existing water resources allocation scheme,as well as the simulation prediction of the guarantee degree of regional water resources allocation in each year.
