河西走廊东部沿沙漠地区作物种植结构调整方案

Crops Planting Structure Adjustment Plan for the Edge of Desert District in the East of the Hexi Corridor

运用系统工程理论中的线性规划方法对地处河西走廊东部沙漠地区民勤县的作物结构进行了调整 ,夏、秋作物比例由原来的 1 :0 .6 5调整为 1 :1 .81时 ,净产值比 2 0 0 0年增加 6 839.4 3万元。并根据不同区域气候特点和产量水平 ,提出了作物布局调整方案 ,对本地优势作物基地建设提供了科学依据。

Using the linear programming method of system engineering theory Minqin County's crops structure is adjusted in the desert east of the Hexi corridor,the summer/autumn crops' proportion is adjusted from 1:0.65 to 1:1.81,the net output value is increased by 6839.43 million yuans than 2000 year.According to different region's climatic feature and yield level,a suggestion about crops' distribution adjustment is put forward,providing a scientific basis for the construction of local optimal crops base.
