摘要: 河西走廊是甘肃省主要经济地区之一,河西走廊未来的经济发展规模在很大程度上取决于本地区水资源的承载能力。本文在水量平衡原理的基础上,对河西走廊水资源的供需平衡和水土资源平衡状况以及水资源对农业发展的承载潜力进行了分析计算,并建立了相应的数学模型,指出了河西走廊水资源的潜力巨大,只有在发展节水型农业和水资源合理、高效利用的条件下才能提高农业用水的承载潜力。

关键词: 河西走廊, 水资源, 供需平衡, 承载潜力

Abstract: he Hexi corridor is one of the main economic regions in Gansu Province. The scale of economic development of the Hexi corridor in the future depends considerably on the carrying capacity of the water resource in the region. On the basis of the balance principle of water quantity this paper analyses and calculates the balance between supply and demand of water resource, the balance between the water resource and the land resource, and the potential of the carrying capacity of water resource for agriculture development in the Hexi corridor. Meanwhile the corresponding mathematical models are set up. The potential of water resource in the Hexi corridor is great. This potential can brought into play step by step only under the following conditions, namely, develo ping the agriculture of the saving water type and using the water resource rationally and efficiently.

Key words: alance between supply and demand, water resource, carrying capacity, Hexi corridor
