疏勒河双塔灌区农业种植结构调整优化研究

The optimization and adjustment of planting structure in Shuangta irrigation district in Shulehe river basin

基于双塔灌区灌溉用水供应量、农作物种植面积、作物类型、作物用水定额等资料,建立线性规划模型,研究在不对社会和生态环境产生负面影响的前提下,当地农作物种植结构将如何调整,以实现经济效益最大化。结果表明:在现有种植总面积不发生明显变化的基础上,粮食作物种植面积应适当增加,使小麦占农作物总种植面积的9.1%,玉米占4.3%;经济作物中,应大幅度增加棉花的种植面积,减小油料、蔬菜、瓜类的种植面积,使油料、蔬菜和瓜类种植面积所占的比例分别为0、1.0%和4.8%;若按规划进行种植结构调整,当地农作物总产值将增加0.18倍。

Based on crop types,total crop area,water supply and consumption quotas in Shuangta irrigation district,poly-linear programming model was established to analyze the optimization of planting structure. The model was established aiming to achieve the highest proceeds and do not have negative effects to our society and environment. The results show that in the recent crop area,grain crop areas should increase in order to let wheat and corn occupy 9. 1% and 4. 3% respectively; For economic crops,planting areas of cotton should increase,while vegetables,cucurbits and oilseeds should be reduced in order to let cotton,vegetables,cucurbits,and oilseeds occupy 80. 8%,1. 0%,4. 8% and 0 respectively. Based on the above optimization,agricultural output can increase 0. 18 times.
