农作物面积变化对新疆水资源结构偏差的影响

农业是新疆的支柱产业,棉花、小麦、玉米作为新疆的主要农作物,既是促进农业节水的重要切入点,又是农业生产与农民增收的重要经济纽带,其种植结构合理与否关系到新疆水资源利用效率的高低。通过对新疆各地区水资源利用结构偏差值的计算,分析新疆各地区的农业用水效率,并计算棉花、玉米、小麦种植面积变化对新疆各地区水资源利用结构偏差的影响,在此基础上,深入分析当前新疆农业种植结构与农业节水效率之间的关系,为今后优化配置新疆水资源提供一定依据。

Effects of Planting Area Change of Cotton,Wheat and Corn on Water Resources Utilization Structure Deviation of in Xinjiang

Agriculture is the pillar estate of Xinjiang.As the main crops of Xinjiang, cotton, wheat, and corn are the important points to promote agricultural water saving and also the important economic link between agricultural production and farmers' income increasing.The reasonability of the cultivation structure has great effects on the water resources utilization efficiency in Xinjiang.Through the calculation of the deviation value of water resources utilization structure in various regions of Xinjiang, the agricultural water use efficiency in different regions of Xinjiang are analyzed, and the influence of the cultivated area changes of cotton, maize and wheat on the structural deviation of water resources utilization in Xinjiang is calculated.Based on it, this paper analyzes the relationship between the agricultural planting structure and agricultural water saving efficiency in Xinjiang, and provides some basis for the optimal allocation of Xinjiang water resources in the future.
