摘要
客观核算城市群水资源生态足迹,对评估区域水资源盈亏状况和衡量水资源的可持续利用具有重要意义。基于“省公顷”修正水资源均衡因子,计算并分析2000~2019年长江中游城市群水资源生态足迹时空演变规律,并利用地理探测器探究其驱动因素。结果表明:(1)2000~2019年长江中游城市群水资源生态足迹整体呈波动增长态势,增幅为34.63%;(2)长江中游城市群水资源生态足迹区域差异显著,其中武汉城市圈水资源生态足迹北部高于南部,环鄱阳湖城市群水资源生态足迹呈“西高东低”的分布格局,环长株潭城市群水资源生态足迹北部和东南部地区高于中部地区;(3)水资源生态足迹强度是长江中游城市群水资源生态足迹时空演变的主要驱动因素,具有最高解释力的交互因子为水资源生态足迹强度和GDP。该研究结果可为决策者因地制宜制定区域水资源管理政策提供科学依据。
The objective calculation of the ecological footprint of water resources in the urban agglomeration in the middle reaches of the Yangtze River was of great significance for assessing the profit and loss of regional water resources and measuring the sustainable use of water resources.In this study,the equivalence factor of the water ecological footprint model was revised according to the“province hectares”.Then,this parameter was applied to the urban agglomeration in the Middle Reaches of the Yangtze River to calculate the water resource ecological footprint and its Spatio-temporal evolution patterns from 2000 to 2019.Finally,based on the Geodetector,the driving factors of the evolution of the ecological footprint of water resources in the urban agglomeration in the middle reaches of the Yangtze River from the four aspects of natural resources,social economy,technological level,and water resources environment was analyzed.The results indicated that:(1)The water resources ecological footprint of the urban agglomeration in the middle reaches of the Yangtze River showed a fluctuating growth trend from 2000 to 2019,with a growth rate of 34.63%.(2)There were significant spatial differences in the ecological footprint of water resources in the urban agglomeration in the middle reaches of the Yangtze River.The water resources ecological footprint in the Wuhan City Group was higher in the north than in the south,and the Poyang Lake City Group showed a distribution trend of“high in the west and low in the east.”The northern and southeastern regions of the water resources ecological footprint in the Chang-Zhu-Tan City Group were higher in the north and southeast than in the central part.(3)The intensity of the ecological footprint of water resources was the main driving factors,and the interaction factors with the highest explanatory power were the intensity of water ecological footprint and GDP.The results could provide a scientific theoretical basis for decision-makers to formulate water resources management policies according to local conditions.
