摘　　要：鉴于新型城镇化发展对水资源利用效率提出了更高的要求,为此基于2010—2019年三峡库区重庆段15个县域的面板数据,运用熵值法和超效率SBM模型分别测算研究区新型城镇化水平和水资源利用效率,并借助Tapio脱钩模型探究二者的脱钩关系。研究结果表明:1) 2010—2019年研究区新型城镇化水平总体上升,新型城镇化水平综合指数由2010年的0.209上升至2019年的0.516。重庆中心城区及周边有关县域的新型城镇化水平综合指数较高,多年平均值在0.4以上;三峡库区重庆段腹地县域新型城镇化水平综合指数多年平均值较低,但年平均增速较快,并逐步缩小与重庆中心城区及周边有关县域该项指标的差距。2)研究区水资源利用效率总体呈“下降—明显上升—小幅回落”的趋势,各县域水资源利用效率时空差异明显,水资源利用效率的变化与地区经济发展水平存在弱相关关系。3)新型城镇化与水资源利用效率脱钩关系由2010—2013年的强脱钩类型主导演变为2013—2016年和2016—2019年的弱脱钩类型主导,总体发展趋势良好;同时受水资源利用效率的不稳定性影响,脱钩关系逐渐复杂化。研究结果提示未来仍需重点关注研究区水资源利用效率提升问题,应结合研究区实际,针对不同县域出现的问题采取相应措施以推动新型城镇化与水资源利用效率的协调发展。In view of the higher requirements of new urbanization development on water resource utilization efficiency,based on the panel data of 15 counties in Chongqing section of the Three Gorges Reservoir Area from 2010 to 2019,entropy method and super efficiency SBM model were used to calculate the new urbanization level and water resource utilization efficiency of the study area respectively,and Tapio decoupling model was used to explore the decoupling relationship and temporal and spatial evolution characteristics of new urbanization level and water resource utilization efficiency.The research results show that:1)From 2010 to 2019,the level of new urbanization in the reservoir area has generally increased,and the average comprehensive index of new urbanization has risen from 0.209 in 2010 to 0.516 in 2019.The comprehensive index of the new urbanization level in the central urban area and surrounding counties of Chongqing are higher,with a multi-year average above 0.4.The comprehensive index of new urbanization level in the hinterland of Chongqing in the Three Gorges Reservoir Area are lower,but the annual average growth rate is faster,and the gap with the central urban area and surrounding counties of Chongqing is gradually narrowed.2)The overall water resources utilization efficiency shows a trend of“decreasing-significantly increasing-slightly decreasing”.There are obvious temporal and spatial differences in water resources utilization efficiency in various districts and counties.There is a weak correlation between changes in water resource utilization efficiency and regional economic development level.3)The decoupling relationship between new urbanization and water resources utilization efficiency has changed from strong decoupling from 2010 to 2013 to weak decoupling from 2013 to 2016 and from 2016 to 2019.The overall development trend is good.At the same time,affected by the instability of water resources utilization efficiency,the types of decoupling relationship are becoming more and more complex.The resea
