水资源的短缺是全球性问题,水资源优化分配是重要的农业节水措施,是目前农业节水研究的重大课题之一。当水资源优化分配中未知量较多时,传统的手工计算方法已不能满足需要,必须用计算机模型来计算。GAMS是国外应用较广的计算机语言,能通过很简单的计算程序迅速求解线性规划、非线性规划、整数规划问题。通过GAMS语言,建立了简单的灌区水资源分配模型,求解了不同水库泄水条件下的各用户最优水量分配方式。
The shortage of water resources is a global issue. Optimal allocation of water resources is an important measure for saving water in agriculture. It is one of the major issues in the study of water conservation in agriculture. When there are more unknowns in the optimal allocation of water resources, the traditional manual calculation method can not meet the needs and must be calculated by the computer model. GAMS is a widely used computer language abroad. It can quickly solve linear programming, nonlinear programming and integer programming through very simple calculation procedures. Through the GAMS language, a simple irrigation water allocation model is established and the optimal water allocation for each user under different reservoir discharge conditions is solved.
