干旱地区灌溉输水供需平衡优化模型

介绍了塔里木盆地灌溉农业输水技术和田间灌溉技术的现状。详细描述了区域间在各种节水技术组合下，不同种植作物的水供需平衡优化模型。以总系统收益最大为目标函数。约束条件考虑了灌溉面积、灌溉作物面积、水供应、需求及平衡、水输送及最大来水量、作物销售量、化肥需求量等。在模型中还引入了水价，买水约束。用线性规划软件包ＧＡＭＳ对该模型进行了计算，结果令人满意。本模型为研究该地区水资源合理分配，提高水利用率提供了一个有效工具，也可推广应用于其它相似地区的水资源利用领域。

Optimal model of the balance between water supply and demand for field irrigation in arid areas

The present condition of water transport and field irrigation technologies applied for irrigation in an arid area Tarim Basin of China are introduced. An optimization model for the water resource Supply Demand balance in this area is developed, in order to find an optimized combination of various water saving technologies and different plant crops with the maximum net income of the overall system being the objective function. The model is well elaborated by taking various constraint conditions with different but inter relevant dimension into account, such as irrigating areas, crops planted areas with irrigation, water supply and demand and their balance, water transportation capacity, maximal discharge of water, sales of crops, chemical fertilizer and its maximal supply, and so on. The optimal solution of the problem has been solved by using standard linear programming(LP) package GAMS with satisfying results. This model is an effective tool to develop rational options for scarce water resources allocation and water utilization rate. The model can be applied to the field of water resource utilization in other similar areas.
