摘要
本文针对我国干旱、半干旱地区农业水资源短缺的特点,提出了建立在非充分灌溉理论基础上的灌溉制度优化模型.该模型是一个两维状态及两维决策变量的多维动态规划模型,可利用动态规划逐次渐近法(DPSA)求解.以黑龙港地区为背景的实例研究结果说明了所建模型及求解方法的合理性和有效性,为节省缺水地区的农业水资源开辟了一条新的途径.
This paper presents an optimization model of irrigation scheduling based on the features of deficit irrigation in the arid and semi-arid regions. The model is a multi-dimension dynamic programming model with two-state and decision variables which can be solved by the DPSA algorithm. The reliability and reasonableness of the model and algorithm have been proved by a case study in the Heilonggang region of North China. A new approach has been developed for saving agricultural water resources in the water shortage regions.
