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。
The Hexi Corridor is one of the major economic areas in Gansu Province. The future economic development scale of the Hexi Corridor depends to a large extent on the carrying capacity of water resources in the region. Based on the principle of water balance, this paper analyzes and calculates the balance between supply and demand of water resources and the balance of water and soil resources in Hexi corridor, as well as the carrying capacity of water resources to agricultural development, and establishes the corresponding mathematical model. Has great potential. Only under the conditions of rational and efficient utilization of water-saving agriculture and water resources can the carrying capacity of agricultural water be enhanced.
