摘　　要：关中平原城市群作为我国西北缺水地区最大的城市群,探讨水资源、社会经济、生态系统的协调关系对实现地区水治理和区域可持续发展意义重大。以关中平原城市群11个地级市为研究对象,通过建立水资源、社会经济、生态系统发展水平测度指标体系,计算2006—2020年三系统发展水平得分,利用耦合协调模型测算分析耦合协调性,并运用障碍度函数探测耦合协调度的主要制约因素。结果表明:(1)2006—2020年关中平原城市群各地级市水资源、社会经济、生态系统发展水平均呈递增趋势且表现出明显的空间分级。(2)城市群的耦合协调度由2006年的轻度失调状态提升至2020年的基本协调状态,在空间上耦合协调度表现为“核心城市>周边城市>外围城市”的发展格局。(3)关中平原城市群11个地级市耦合协调度的主要障碍因子表现出明显差异,根据障碍因子结果水资源-社会经济-生态系统协调发展模式可分为水源限制下的综合发展模式(核心城市)、生态环境落后模式(周边城市)和社会经济落后模式(外围城市)3种类型。The Guanzhong Plain urban agglomeration is the largest urban cluster in the water-scarce region of northwest China.Exploring the coordination among water resources,the socio-economic system,and the ecosystem is crucial for regional water governance and sustainable development.This study examines 11 prefecture-level cities within the Guanzhong Plain urban agglomeration.By establishing a comprehensive evaluation index system for the coordinated development of water resources,socio-economic,and ecological systems,the comprehensive evaluation indices of these three systems from 2006 to 2020 are calculated.The coupling coordination model is employed to measure and analyze their coordination,while the obstacle degree function is used to identify the primary constraints affecting the coupling coordination degree.The results indicate that:(1)From 2006 to 2020,the development levels of water resources,socio-economic,and ecological systems across the cities in the Guanzhong Plain urban agglomeration exhibited an overall upward trend with distinct spatial gradation.Cities with higher water resource system levels include core and surrounding cities,while those with higher socio-economic system levels are predominantly core cities.Prefecture-level cities with higher ecological system levels are either core or peripheral cities.(2)The coupling coordination degree of the Guanzhong Plain urban agglomeration improved from a state of slight imbalance in 2006 to basic coordination by 2020.Spatially,the coupling coordination followed a hierarchical pattern of“core cities>surrounding cities>peripheral cities”.(3)Significant differences exist in the primary obstacles affecting the coupling coordination degree across the 11 prefecture-level cities.Based on the detection results of obstacle factors,the coordinated development of the water-socio-economic-ecosystems in the study area can be categorized into three types:comprehensive development constrained by water resources(core cities),ecological environment lagging behind(surroundi
