This study builds upon the traditional ecological footprint model by adding two new accounts of resource flows and using two new calculating method. This first account concerns water resources and accounts for water consumption in cities. The second account tracks basic types of pollutant accounts. Energy theory and net primary productivity were used to calculate the ecological footprint. Aiming at the problem of application in city, a city hectare spatial scale was used and a regional carrying capacity correction parameter was referenced. This framework provides insight into calculations of the bearing capacity of certain areas. The Wuhan City Circle was used as a case study with the objectives of calculating the ecological footprint and regional carrying capacity and analyzing its spatiotemporal evolution and capacity for sustainable development. The results indicated that from 2000 to 2015, the average annual rate of decline of the carrying capacity of the Wuhan City Circle was 9.18%, and from 2015 to 2017, the average annual rate of increase was 38.91%. The ecological footprints of fossil energy and build-up land accounts increased over the years, exposing problems with land and energy utilization in the Wuhan City Circle. The continuous decline of the water resources carrying capacity reminds policy makers to pay attention to the protection of water areas. These results can help policy makers integrate historical data to adjust existing plans and make more specific future plans.

基于改进生态足迹法确定武汉城市圈区域承载力

本研究建立在传统生态足迹模型的基础上，增加了两个新的资源流账户，并使用了两种新的计算方法。第一个账户涉及水资源和城市用水量。第二个账户跟踪污染物账户的基本类型。能源理论和净初级生产力被用来计算生态足迹。针对城市应用问题，采用城市公顷空间尺度，参考区域承载力修正参数。该框架提供了对某些区域承载力计算的深入了解。以武汉城市圈为例，计算生态足迹和区域承载力，分析其时空演变和可持续发展能力。结果表明，2000年至2015年，武汉城市圈承载力年均下降率为9.18%，2015年至2017年，年均增长率为38.91%。化石能源和建设用地账户的生态足迹逐年增加，暴露出武汉城市圈土地和能源利用的问题。水资源承载力的持续下降，提醒决策者重视水域保护。这些结果可以帮助决策者整合历史数据来调整现有计划，并制定更具体的未来计划。91%。化石能源和建设用地账户的生态足迹逐年增加，暴露出武汉城市圈土地和能源利用的问题。水资源承载力的持续下降，提醒决策者重视水域保护。这些结果可以帮助决策者整合历史数据来调整现有计划，并制定更具体的未来计划。91%。化石能源和建设用地账户的生态足迹逐年增加，暴露出武汉城市圈土地和能源利用的问题。水资源承载力的持续下降，提醒决策者重视水域保护。这些结果可以帮助决策者整合历史数据来调整现有计划，并制定更具体的未来计划。
