干旱地区农作物有限水源灌溉系统优化算法

摘要

为了提高农业作物投入产出比，提出了一种适合干旱地区农业自动灌溉系统的优化控制方法。算法以带精英策略的非分支排序遗传算法（ NSGA-II ）为基础，以滴灌系统总费用最小和农业效益最大为目标函数，以灌溉系统和农作物需求为约束，基于不充分灌溉原理，实现了在总体供水不足的情况下节水灌溉的优化配置。伊犁地区水资源优化配置仿真表明，该算法是有效、可行的。%In order to improve the input-output ratio of agricultural crops , optimization control method for agriculture au-tomatic irrigation system of Xinjiang region is presented .The algorithm based on elitist strategy No-Sorting Genetic Algo-rithm ( NSGA-II) aims at maximize the profit of the crops and minimize the total cost of the inadequate supplying irriga -tion system with drip irrigation systems and crop requirements constraints .The Method presented realized the optimal allo-cation of water resources of the overall on the basis of inadequate irrigation principles .The simulation of the optimal allo-cation of water resources in YiLi region shows that the algorithm can obtain higher efficiency and saving agricultural water resources .
