摘要
针对松原市的灌溉水资源不足以及灌溉利用率不高的问题,综合考虑农业可持续发展的经济效益、社会需要和生态效益要求,基于熵权系数法的基本原理,构建了多准则的灌溉水资源优化调配的模型,确定了研究区农业种植最优模式以及相应的合理灌溉用水量。模型结果表明,该区玉米、大豆、水稻3种作物的最优种植面积分别为46.81万、1.60万、6.25万hm2,相应合理的灌溉水量分别为2.0亿、240.0万、4.1亿m3。
Aiming at the problems of shortage of irrigation water resources and low irrigation utilization rate in Songyuan City,the economic benefits,social demand and ecological benefits of agricultural sustainable development were considered comprehensively,moreover,a multi-criteria irrigation water resource optimization model had been constructed based on fundamental principles of entropy weight coefficients methods,in addition,the optimal models about the agricultural planting and the corresponding rational irrigation water amount in research areas were determined.The results indicated that the optimal planting areas of maize,soybean and paddy rice were 46.81×104,1.60×104 and 6.25×104 hm2 and the corresponding rational irrigation water amount were 2.0×108,2.4×106 and 4.1×108 m3,respectively.
