【摘要】 西北干旱区深处亚欧大陆中部,自然条件恶劣,为"非灌不植"区域,水资源利用是否合理密切关系到作物生长的成效和社会经济的发展。本文通过相关分析等统计方法,定量分析了西北干旱区农业用水和作物产量的关系研究发现,西北三省区多年来农业用水效率提高明显,新疆尚有较大提升空间,内蒙单位面积农业用水量偏低影响了作物生产,甘肃农业发展则主要受限于水资源总量和时空分配不均。更多还原

【Abstract】 The north-west arid zone in central Asia-Europe land with bad natural conditions is " no-irrigation no-yield" region.A reasonable use of water resources is closely related to the crop production.Statistical methods such as correlation analysis are used in this paper.The study show that the efficiency of water use has develop a lot since1995,and Uygur Autonomous Region keeps the capacity to go further.The water use per hectare in Inner Mongolia is short which do a negative effect on the agriculture yield,while the agricultural development of Gansu province is mainly restricted to the total water resources and uneven distribution of water in time and space.This article also gives some suggestions to improve the efficiency of water use and increase agricultural yield.更多还原
