摘　　要：虚拟水战略为解决水资源短缺问题提供新的想法与措施。借助CROPWAT8.0软件,利用CROP数据库、CLIMATE2.0数据库和《宁夏统计年鉴》等资料,对宁夏三大产业用水进行评价,分析了农业虚拟水战略的可行性;通过计算典型农作物虚拟水含量筛选虚拟水战略作物,设定六种不同方案进行适宜性情景模拟。结果表明,在保障粮食安全基础上,春小麦可作为农业虚拟水战略首选优势作物,减少或替代种植可一定程度上增加效益,减少用水量。The virtual water strategy provides new ideas and measures to address water shortages.This paper used CROPWAT 8.0 software,CROP database,CLIMATE 2.0 database and Ningxia Statistical Yearbook to evaluate the water consumption of the three main industries in Ningxia,and analyzed the feasibility of agricultural virtual water strategy.Besides,the virtual water contents of the typical crops were calculated.Then,the virtual water strategic crops were screened and six different scenarios were set up for suitability simulation.The results show that the spring wheat can be used as the preferred crop of the virtual water strategy based on the food security.To some extent,the reduction or substitution of planting can increase the efficiency and reduce the water consumption.
