On the basis of spring-wheat requiring-water regulation,referring to deficient irrigation experiment data of spring-wheat,and using dynamic programming theory,this thesis develops the optimization model of spring-wheat irrigation system. The aim of model is to reduce the irrigation quota during growing-period.
根据春小麦的需水规律,应用动态规划理论和非充分灌溉原理,参照灌区春小麦的非充分灌溉实验资料,以减小生育期的灌溉定额为目的,建立了春小麦灌溉制度优化模型。

Under the limited irrigation, the water shortage was only 8.73×106m3 when scheme 2 was adopted, and decreased the water supply of the irrigation districts apparently to loose the water supply pressure and groundwater exploitation compared with other schemes.
在非充分灌溉条件下,采用方案2配水,使得灌区缺水量仅为767万m3,对比其它情景,可以比较明显得减少灌区的需水量,减轻供水压力,同时也减少地下水的开采量。
