摘　　要：在水足迹视角下,从经济和资源两个方面,选取经济增加值、机会成本、耕地面积和水资源禀赋4个指标,借助基尼系数系统地构建了公平性评价模型,对2015—2020年中国粮食生产用水公平性进行研究。结果表明,从时间维度来看,2015—2020年中国粮食生产用水整体情况处于“绝对公平”,预测水资源禀赋未来可能成为制约中国粮食生产用水公平的主要因素。从空间维度来看,中国大部分省(市、自治区)属于低度不公平地区,高度不公平省(市、自治区)主要集中在中国西部及北部地区。在此基础上,提出建立科学合理的生态补偿机制,推进跨区域水资源规划合作,因地制宜优化产业结构,推进“两区”科学管护工作,以提高中国粮食生产用水区域公平性,缓解区域水资源压力。From the perspective of water footprint,four indicators of economic added value,opportunity cost,cultivated land area and water resource endowment were selected from both economy and resource aspects.With the help of Gini coefficient,the fairness evalu-ation model was systematically constructed to study the fairness of water for grain production in China from 2015 to 2020.The results showed that from the perspective of time dimension,the overall situation of water for grain production in China was in the state of“ab-solute fairness”from 2015 to 2020,and water resource endowment would be the main factor restricting the fairness of water for grain production in China in the future.From the perspective of spatial dimension,most provinces(municipalities and autonomous regions)in China belonged to low unfairness areas.High unfairness provinces(municipalities and autonomous regions)were mainly located in the western and northern regions of China.Based on this,suggestions were put forward to improve regional fairness of water use for grain production in China and alleviate regional water pressure,such as establishing a scientific and reasonable ecological compensa-tion mechanism,pushing cross-regional water planning cooperation,optimizing the industrial structure according to local conditions and promoting the scientific management and protection of the“two districts”.
