甘肃河西走廊水资源供需分析及耕作节水研究

根据河西走廊有62.42×10⁸ m³地表水资源、4.94×10⁸ m³地下水资源和每年耗水70.44×10⁸ m³的矛盾，分析了水对这一地区的影响，指出了河西走廊只能靠减少水分蒸发、农业节约用水、提高水的利用率和灌水生产效率来实现水资源的平衡。在试验的基础上 ，提出了灌水生产率比传统耕作高60.78％和节水41.29%的保护性耕作方法。

Analysis of the supply of and demand for water resource and research on water-saving tillage in Hexi corridor of Gansu Province

In the light of the natural resources of 62.42×10⁸ m³ surface water and 4.94×10⁸ m³ groundwater and the contradiction of consuming 70.44×10⁸ m³ water resource in the Hexi corridor of Gansu Province, the effects of water on Hexi corridor were analyzed. Only by relying on decreasing water evaporation, saving agricultural consumption of water, raising use efficiency and production efficiency of irrigation water, the water resource balance can be realized. On the basis of experiments, a new conservation tillage method was proposed, through which the productivity increased by 60.78% and 41.29% water could be saved compared with traditional tillage method in the Hexi corridor.
