摘 要:基于水足迹理论视角分析了湖北省水足迹的结构特征和水资源利用的水平。分析表明:(1)湖北省的水足迹和农业水足迹整体呈现波动上升的趋势,工业水足迹呈现波动下降的趋势,其中农业水足迹占湖北省水足迹的87.8%,说明湖北省的水足迹结构差异明显;(2)湖北省水资源利用与经济增长的趋势呈现弱脱钩趋势,湖北省的经济向好方向发展,产业结构较为合理,而技术效应和经济规模方面造成主要的水资源浪费;(3)湖北省各地水足迹强度整体呈现明显下降趋势,水资源利用效率逐渐提高,但部分区域水足迹强度相对较高,水资源利用效率仍可提升;(4)湖北省水足迹强度存在着显著的空间自相关关系,主要呈现低-低和高-低的空间聚类方式,并且具有明显向周边扩散的趋势。According to the water footprint theory,the structural characteristics of water footprint and the level of water resources utilization in Hubei Province were analyzed.The analysis results show that:①The water footprint and agricultural water footprint in Hubei Province generally rise with fluctuations,while the industrial water footprint decreases with fluctuations.The agricultural water footprint accounts for 87.8%of the water footprint in the province,which indicates that the water footprint in Hubei Province has significantly different structures.②The water resources utilization and economic growth in Hubei Province show a weak decoupling trend.The economy of Hubei Province develops positively,and the industrial structure is reasonable.The technical effect and economic scale cause major waste of water resources.③The overall water footprint intensity in Hubei Province significantly drops,and the water resources utilization efficiency gradually improves.However,the water footprint intensity in some regions is relatively high,and the water resources utilization efficiency can still be improved.④The water footprint intensity in Hubei Province has a significant spatial autocorrelation,which mainly presents low-low and high-low spatial clustering patterns,and it has an obvious tendency to spread to the surrounding areas.
