摘要
主要探讨人工回灌情况下的灌区水资源管理问题。将研究区域的整个地下含水层视为单一单元 ,分别介绍了该单一单元的各个输入变量和输出变量 ,基于地下水的水均衡方程 ,得到了可用于对灌区的水资源进行有效管理的数学模型。文中举一示例介绍该模型的应用 ,结果表明该模型可用来确定需要抽取的地下水量以及地下含水层的蓄水量 ,为灌区的水资源规划管理提供有益的指导。
Problems in water resources management in irrigation areas with artificial recharge of groundwater are analyzed and discussed in this paper. The entire aquifer in the case study area is considered as a single cell, and all inflow variables and outflow variables are introduced. A mathematical model, based on water balance equation, is developed for irrigation area water resources management. A case study indicates that the model has good precision and reliability for determining available water resources volume in entire aquifer, and is helpful for water resources development.
