摘　　要：为定量分析小尺度上水资源可持续利用现状,采用基于“市公顷”的水资源生态足迹模型,结合三维生态足迹理论,探讨运城市2011—2020年水资源生态足迹及生态承载力的时间变化和空间差异;并利用扩展后的STIRPAT模型分析运城市水资源生态足迹变化的驱动因素。结果表明,“市公顷”下运城市水域均衡因子和产量因子区域特征明显;水资源生态足迹整体为先升后降趋势,水资源生态承载力整体为上升趋势;运城市水资源历年均处于生态赤字状态,平均足迹深度3.09;各行政区中,仅垣曲县为水资源盈余状态,其余区域均处于不同程度的水资源赤字状态;水资源消费强度为运城市水资源生态足迹的主要驱动因素,人口规模与水资源生态足迹呈反向作用。To quantitatively analyze the current status of water resource sustainable utilization at a small scale,a water resource ecological footprint model based on“hectare per capita”is adopted.Combined with the three-dimensional ecological footprint theory,this paper explores the temporal changes and spatial differences of water resource ecological footprint and ecological carrying capacity in Yuncheng City from 2011 to 2020.Additionally,an extended STIRPAT model is used to analyze the driving factors of changes in the water resource ecological footprint in Yuncheng City.The results reveal significant regional characteristics of the water balance factor and yield factor in water areas under the“hectare per capita”approach.The overall trend of the water resource ecological footprint shows an initial increase followed by a decrease,while the ecological carrying capacity exhibits an overall upward trend.Yuncheng City has consistently experienced an ecological deficit in water resources over the years,with an average footprint depth of 3.09.Among the administrative regions,only Yuanqu County demonstrates a surplus of water resources,while the remaining areas experience varying degrees of water resource deficit.The intensity of water resource consumption is identified as the main driving factor for the water resource ecological footprint in Yuncheng City,while the population size has an inverse relationship with the water resource ecological footprint.
