摘　　要：基于水足迹理论,计算并分析山西省2010-2020年粮食生产蓝水、绿水足迹、主要能源的蓝水足迹、灰水足迹、水资源的集约利用度、水资源压力指数、水-粮食-能源竞争指数的变化情况。结果表明:山西省2010-2020年粮食生产绿水足迹、蓝水足迹呈先波动上升后下降的趋势,于2016年达到最大,且谷类水足迹占比最大;能源生产水足迹呈现出上升—下降—上升三个阶段;水资源的集约利用度基本稳定,2016年后大幅增长;水资源压力指数呈现波动下降的趋势;水—能源—粮食竞争指数整体在2左右浮动,其中2012年、2015年、2018年以及2019年为激烈竞争,其余年份为强竞争。建议山西省积极提升可再生能源的利用效率。In order to explore the relationship among water-food-energy in Shanxi Province and actively promote the energy revolution in Shanxi Province,this paper calculated and analyzed the changes of blue water and green water footprint,blue water footprint of major energy sources,gray water footprint,intensive utilization of water resources,water resource stress index and water-food-energy competition index of grain production in Shanxi Province from 2010 to 2020 based on the water footprint theory.The results showed that the green water footprint and blue water footprint of grain production from 2010 to 2020 indicated a trend of first fluctuating and rising and then declining,reached the maximum in 2016.The cereal water footprint accounted for the largest proportion.The water footprint of energy production showed three stages of rising,falling-rising.The intensive utilization of water resources was basically stable and increased significantly after 2016.The water resources pressure index showed a fluctuating downward trend.The water-energy-food competition index as a whole floated around 2,of which 2012,2015,2018 and 2019 were fierce competition,and the rest of the year were strong competition.It is recommended that Shanxi Province actively improve the efficiency of renewable energy utilization.
