摘　　要：如何测度和解析喀斯特地区水资源分布格局及其利用效率,及其与社会经济发展水平的协调度,使该喀斯特地区提升水资源利用效率、提升社会经济发展质量和加速生态文明建设亟需研究的热点问题之一。在对2010-2021年间喀斯特区域的水资源和社会经济的时空数据进行收集处理的基础上,首先采用超效率SBM-DEA模型对近10年来西南喀斯特地区36个地级市水资源利用效率进行定量测度。其次集成空间相关分析模型和脱钩模型对水资源利用效率时空差异格局及其与经济发展水平的适配状态进行定量判定。研究结果表明:近10年来西南喀斯特地区水资源利用效率总体呈上升趋势,但利用效率的整体偏低,由2010年的0.383上升到2021年的0.484,且有89%的地级市水资源利用效率变动趋势与整体一致;西南喀斯特地区水资源利用效率空间分布综合呈“n”字型分布,靠近贵州省区域相对较高,邻近云南省和广西两侧相对较低,且水资源利用效率空间相关性不明显,但集聚程度呈增加趋势;水资源效率与经济发展水平的适配程度呈上升趋势,但扩张性负脱钩类型明显增多。How to measure and analyze the distribution pattern and utilization efficiency of water resources in Karst area,as well as the coor⁃dination degree with the level of social and economic development,is one of the hot issues that need to be studied to improve the efficiency of water resources utilization,improve the quality of social and economic development and accelerate the construction of ecological civilization in the karst region.On the basis of collecting and processing the spatio-temporal data of water resources and social economy in karst region during 2010-2021,this paper firstly adopts super-efficiency SBM-DEA model to quantitatively measure the water resources use efficiency of 36 prefecture-level cities in the karst region of Southwest China in recent 10 years.Secondly,the spatial correlation analysis model and de⁃coupling model are integrated to quantitatively determine the spatio-temporal difference pattern of water resource use efficiency and its adap⁃tation state to economic development level.The results show that:in the past 10 years,the water resources use efficiency in southwest karst areas has shown an overall increasing trend,but the overall utilization efficiency is low,rising from 0.383 in 2010 to 0.484 in 2021,and the change trend of water resources use efficiency in 89%of prefecture-level cities is consistent with the overall trend.The spatial distribution of water resources use efficiency in the southwest Karst region showed an“n”shape,with relatively higher distribution near Guizhou province and relatively lower distribution near Yunnan Province and Guangxi Province.The spatial correlation of water resources use efficiency was not obvious,but the degree of agglomeration showed an increasing trend.The degree of adaptation between water resources efficiency and economic development level showed an increasing trend,but the types of expansionary negative decoupling increased significantly.
