西北地区水资源与食物安全可持续发展研究

Sustainable Development of Water Resources and Food Security in Northwest China

西北地区光热土资源丰富,区域食物安全的可持续发展主要受限于其有限的水资源。本文以水足迹和虚拟水为分析工具,评估了西北地区作物生产用水效率、水资源压力和作物虚拟水输出情况。基于国际化绿色化背景,以及西北地区粮食生产及农业用水的预测结果,提出逐步减少区域农业用水总量,优化调整作物种植结构和实施丝路经济带虚拟水工程,以期为区域水资源合理利用和食物安全战略的制定提供参考。

Northwest China has abundant light,heat,and land resources,but limited water resources which has restricted the sustainable development of food security in this region.Water-use efficiency in crop production,water resources stress,and virtual water output of crops in Northwest China are evaluated using water footprint and virtual water as analysis tools.Grain production and agricultural water use in Northwest China are predicted.Furthermore,policy suggestions are proposed to guarantee the sustainable development of water resources and food security in Northwest China,including gradually reducing the scale of agricultural water use in this region,optimizing the crop planting structure,and implementing a virtual water project along the Silk Road Economic Belt.This study is hoped to provide a reference for the rational utilization of regional water resources and the formulation of food security strategies.
