摘要
由于灌区水资源的短缺,作物种植结构调整成为解决水资源问题的关键措施.灌区经济效益最大以及保证粮食安全是灌区发展的目标,本文通过对七星渠灌区的研究分析,建立多目标规划数学模型,通过matlab遗传算法编程,求得多种种植方案.分析比较求解方案以及实际灌区种植结构,再结合灌区已有的规划,最终得到七星渠灌区最优的种植结构,为科学指导生产实践提供了理论依据.
Because of water shortages in irrigation district,planting structure adjustment is the way to solve the key problems of water resources.The development of irrigation district＇ s aim is to realize the maximum economic benefit and ensure food safety.This paper establishes mathematical model of multi-objective programming based on the target of analysis,then solves the multiple cropping scheme programming through matlab genetic algorithm.We get the optimal planting structure of qixingqu irrigation district by Analysis actual planting structure and the irrigation district of planning which provides theory basis For the scientific guidance for the production practice.
