[Establishment and Application of Performance Evaluation and Obstacle Diagnosis Model for Regional Water Ecological Civilization Construction].

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.
