摘　　要：为定量分析区域水资源压力大小,评价水资源可持续发展现状。基于水资源生态足迹模型,分析2005—2019年期间,广州市生态足迹和生态承载力的时间变化及空间差异,结果表明:广州市人均水资源生态足迹逐年减小,人均水资源承载力同水资源总量变化一致,波动较大,水资源呈现盈余状态,万元GDP水资源生态足迹逐年降低,广州市水资源账户总体处于安全状态。广州市人均水资源生态足迹较大的区域分布在黄埔区和南沙区,白云区、天河区、海珠区水资源生态足迹较小。各区人均水资源承载力分布为:从化区>增城区>花都区>南沙区>黄埔区>番禺区>中心区。根据分析结果,建议广州各行政区根据政府规划,结合水资源实际分布与利用状况,进行产业升级,提高用水效率,实现水资源可持续利用。In order to quantitatively analyze the pressure of regional water resources and evaluate the status of sustainable development of water resources.Based on the ecological footprint model of water resources,this paper analyzes the temporal and spatial differences of ecological footprint and ecological carrying capacity in Guangzhou from 2005 to 2019.The results show that the per capita ecological footprint of water resources in Guangzhou is decreasing year by year,the per capita water resources carrying capacity is consistent with the total amount of water resources,and the fluctuation is large.The water resources are in surplus,and the ecological footprint of water resources per 10000 yuan GDP is decreasing year by year.The water resources account of Guangzhou is in a safe state.The regions with larger ecological footprint of water resources per capita are located in Huangpu and Nansha District,while those in Baiyun,Tianhe and Haizhu District are smaller.The distribution of per capita water resources carrying capacity of each district is:Conghua District>Zengcheng District>Huadu District>Nansha District>Huangpu District>Panyu District>Central District.According to the analysis results,it is suggested that the administrative regions of Guangzhou should upgrade their industries according to the government planning and the actual distribution and utilization of water resources,so as to improve the water use efficiency and realize the sustainable utilization of water resources.
