Water scarcity limits the coordination between economic development and ecological protection of arid regions. This study presented the consumption pattern and future challenges for water resources and proposed sustainable use strategies for water security in Yanchi county from the arid region of northwest China. Our results showed that water withdrawals were close to the total available water resources. Agriculture consumed about 84.72% of the total water supply. Agricultural water use was influenced by breeding stock, rural per capita net income and effective irrigation area. Estimation of agricultural water demand was about 6582.20 × 10 m under the rural revitalization scenario. Limited water supply and increased water demand pose challenges and impediments for rural revitalization and water security in Yanchi county. Water sustainable utilization can be achieved by increasing water supply from unconventional water resources and improving water use efficiency with governmental management. These findings may help policymakers to develop sustainable water use strategies during rural revitalization in arid regions.
水资源短缺限制了干旱地区经济发展与生态保护的协调。本研究从中国西北干旱地区的盐池县出发，探讨了水资源的消费模式和未来面临的挑战，提出了水资源安全的可持续利用策略。结果表明，取水量已接近总可用水资源量。农业用水约占总供水量的 84.72%。农业用水受牲畜数量、农村人均纯收入和有效灌溉面积的影响。在乡村振兴情景下，农业需水量估计约为 6582.20×10 m。有限的供水和不断增加的用水需求对盐池县的乡村振兴和水安全构成了挑战和障碍。通过增加非常规水资源的供水和提高政府管理下的用水效率，可以实现水资源的可持续利用。这些发现可能有助于政策制定者在干旱地区的乡村振兴过程中制定可持续的水资源利用策略。
