A scientific performance evaluation of the regional water ecological civilization construction and clarifying the obstacle factor are key points to improve the performance of regional water ecological civilization construction theory. This study analyzes the coupling relationship between humans and regional water ecology by applying the thinking logic of "driving force-pressure-state-influence-response-management." The regional water ecological civilization construction performance evaluation index system based on the DPSIRM model was established. Combining the unascertained measurement model and obstacle diagnosis model, the water ecological civilization construction performance of Shizuishan City during the past 10 years was empirically evaluated, and the obstacle factors affecting local construction performance were diagnosed and analyzed. The analytical results reveal the following points:First, the performance of the water ecological civilization construction in Shizuishan City gradually increased annually and revealed three development stages:the site visit and slow improvement (2010-2014), intermediate but fast improvement (2015-2017) and good and fast improvement (2018-2019). Second, each subsystem performance index trend varied, but generally, the fluctuations rose. Third, from 2010 to 2014, the average obstacle degree of the subsystem state, subsystem response, and subsystem pressure reached 58.81%, which became the main obstacles restricting the performance of the local water ecological civilization construction. From 2015 to 2017, the average pressure barrier degree reached 21.73%, which was the most significant obstacle to the construction performance. From 2018 to 2019, the average pressure barrier degree remained the largest obstacle by reaching 24.49%. Lastly, the index barrier of the obstacle degree among the top five factors are primarily distributed in the pressure subsystem. A comprehensive frequency ranking of the obstacles, the irrigation water use coefficient, and the pressure of the water consumption per ten thousand yuan of value-added by industry as a representative subsystem are the key directions to future construction. In this paper, the concepts and methods of the research can provide a theoretical reference for the performance evaluation of regional water ecological civilization construction and its obstacle factor diagnosis analysis.
对区域水生态文明建设进行科学的绩效评价并厘清障碍因素，是提升区域水生态文明建设理论绩效的关键所在。本研究运用“驱动力—压力—状态—影响—响应—管理”的思维逻辑，剖析人类与区域水生态之间的耦合关系。构建了基于DPSIRM模型的区域水生态文明建设绩效评价指标体系。结合未确知测度模型和障碍诊断模型，对石嘴山市近10年的水生态文明建设绩效进行实证评价，并对影响当地建设绩效的障碍因素进行诊断分析。分析结果表明：一是石嘴山市水生态文明建设绩效逐年递增，呈现出实地考察与缓慢提升（2010—2014年）、中等但快速提升（2015—2017年）以及良好且快速提升（2018—2019年）三个发展阶段。二是各子系统绩效指标趋势各异，但总体呈波动上升态势。三是2010—2014年，子系统状态、子系统响应和子系统压力的平均障碍度达58.81%，成为制约当地水生态文明建设绩效的主要障碍。2015—2017年，平均压力障碍度达21.73%，是建设绩效最显著的障碍。2018—2019年，平均压力障碍度达24.49%，仍是最大障碍。最后，障碍度排名前五的因素中指标障碍主要分布在压力子系统。综合障碍频次排序，灌溉水利用系数以及作为代表性子系统的万元工业增加值用水量压力是未来建设的关键方向。本文的研究理念与方法可为区域水生态文明建设绩效评价及其障碍因素诊断分析提供理论参考。
