摘　　要：以2000—2021年全国287个地级及以上城市为对象,基于生态足迹理论,运用TAPIO脱钩理论和对数平均迪氏指数法(LMDI)构建TAPIO-LMDI模型研究了水资源利用与经济高质量发展的脱钩关系。结果表明:我国不同地区间水足迹存在较大差异,但全国总用水足迹趋于稳定,且水资源生态盈亏在研究期内有所改善;整体上我国经济高质量发展指数逐渐提升,与水资源利用呈脱钩状况;脱钩驱动因素分解结果显示,促进脱钩的主要因素包括技术和结构因素,而抑制脱钩的因素主要为城镇化率和人口数量。提出要制定因地制宜的水资源管理政策、提高水资源利用效率、加强节水宣传与教育等优化建议。This paper takes 287 cities at and above the prefecture level in China from 2000 to 2021 as subjects,based on the ecological footprint theory of water resources,the TAPIO-LMDI model was constructed by using decoupling theory and LMDI method to study the decoupling relationship between water resources utilization and high-quality economic development.The results indicate that there are significant differences in water footprint between different regions in China,but the total water footprint in the country is showing a trend of stabilization,and the ecological profit and loss of water resources have improved during the research period.Overall,the high-quality development index of China’s economy is gradually improving,showing a decoupling from water resource utilization.The decomposition results of decoupling driving factors show that the main factors promoting decoupling include technological and structural factors,while the factors inhibiting decoupling mainly involve the improvement of urbanization rate and the increase of population.It is suggested that water resource management policies should be formulated according to local conditions,water resource utilization efficiency should be improved,and water saving publicity and education should be strengthened.
