有限供水条件下农田灌溉时量优化——以河北省运东地区为例

THE TIME AND QUANTITY OPTIMIZATION OF FIELD IRRIGATION UNDER THE CONDITION OF A LIMITED WATER SUPPLY——A CASE STUDY OF THE YUNDONG REGION OF HEBEI PROVINCE

本文探讨了灌溉水源限定条件下,农田灌溉时量优化计算方法,并以河北省运东地区3种主要作物为例进行了系统演算。从计算结果及其分析看,时量优化的经济效益明显,时量优化模型作为一种计算方法亦具有一定的实用意义。

This paper explores a calculation method of time and quantity optimization for field irriga tion under the condition of a limited water supply. Used as an example, three main crops in the Yundong region, Hebei Province, are systematically calculated. The results and analysis of the systematic calculation show that the use of the time and quantity optimization model can bring about obvious economic benefits for crop production and that the model as a calculation method also has certain practical significance.
