摘要
在对水资源系统进行模拟分析的基础上,结合江苏省南水北调受水区水文水资源、水利工程等特点,构建流域降雨径流模型、水动力学模型、水量调配模型以及水工程调度模型等子模型,对受水区水资源量、供需水量等进行研究。基于所建模型提出水利工程调度方案,对研究区水资源进行合理配置。分别模拟计算分析研究区内农业、工业、生活、生态和船闸用水户在现状与规划工情下不同水平年的供水、需水、缺水情况,制定水资源配置方案。通过现状与规划方案对比可知,南水北调一期工程建成后供水能力提高,缺水量显著降低。95%、75%和50%保证率下,缺水率分别降低10.3%、8.0%和5.2%。研究成果为南水北调东线水利工程调度提供科学依据,对跨流域调水工程的水资源配置与调度具有一定参考意义。
On the basis of water resources system analysis and characteristics of hydrology and water conservancy projects, the precipitation and runoff model, hydrodynamic model, water quantity allocation model, and water project scheduling model were constructed to investigate the water resources quantity and water supply and demand in the river basin. Water conservancy project scheduling scheme was proposed based on the constructed models and applied to perform reasonable allocation of water re sources in the study area. The water supply, water demand, and water deficit in agriculture, industry, life, ecology, and lock under the current and planning engineering conditions were simulated, and the corresponding allocation schemes of water resources were established. Through the comparison between the current and planning conditions, water supply capacity can increase while water deficit can decrease after the implementation of the first stage of the South-to-North Water Transfer Project. Under the assurance rates of 95 %, 75%, and 50 %, annual water deficit rate decreases by 10. 3 %, 8. 0%, and 5. 2%, respectively. The research can provide scientific reference for the water conservancy proiect scheduling in the Eastern Route of the South to-North Water Transfer Project,and is of significance for the water resources allocation and scheduling of the inter-basin water conservancy proiect.
