摘　　要：水足迹理论为解决水资源短缺问题提供了新的研究方向。基于水足迹理论,借助CROPWAT8.0软件,利用《宁夏统计年鉴》和《宁夏水资源公报》等资料,计算分析了宁夏固原市2009-2017年主要作物的蓝水、绿水和灰水足迹。结果表明:蓝水足迹占比最高,绿水足迹次之,灰水足迹最少。表明固原市农作物生产用水以蓝水为主,绿水为辅,灰水足迹虽然占比较少但逐年递增。建议当地根据水资源具体情况,调整作物种植模式,提高绿水利用率,减少氮肥使用率,使有限的水资源获得更大的效益,从而满足粮食安全和水生态安全的需求。The water footprint theory provides a new research direction for solving the water shortage problem.Based on the water footprint theory,this paper used the data from Ningxia Statistical Yearbook and Ningxia Water Resources Bulletin to calculate and analyze the blue,green and grey water footprints of the main crops in Guyuan,Ningxia,from 2009 to 2017,with CROPWAT8.0 software.The results showed that the blue water footprint acounted for the highest proportion,the green water footprint came second,and the grey water footprint was the least.It indicated that the water used for crop production in Guyuan City was mainly blue water,and supplemented by green water.Although the gray water footprint is relatively small,it is increasing year by year.It is recommended to adjust the local crop planting patterns according to the specific conditions of water resources,in order to increase the utilization rate of green water,and reduce the use rate of nitrogen fertilizer,and therefore to achieve greater benefits from limited water resources and meet food security and water ecological security needs.
