摘要
科学评价区域水生态文明建设绩效并明确其障碍因子,是提升区域水生态文明建设绩效的理论依据.本文应用"驱动力-压力-状态-影响-响应-管理"这一思维逻辑解析了人类与区域水生态间的耦合关系,建立了基于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与障碍诊断模型,实证评估了石嘴山市近10年的水生态文明建设绩效并对影响当地建设绩效的障碍因子进行了诊断分析.结果表明:(1)石嘴山市水生态文明建设绩效逐年升高并呈现差且缓慢提升(2010~2014年)、中级但快速提升(2015~2017年)和良好且较快提升(2018~2019年)这3个发展阶段;(2)各子系统绩效指数演变趋势各异,但基本都呈现波动上升态势;(3)各子系统障碍度呈阶段性变化特征,2010~2014年,状态子系统、响应子系统和压力子系统其障碍度均值和达到58.81%,成为制约当地水生态文明建设绩效的主要障碍因子;2015~2017年,压力障碍度均值达到21.73%,是制约当地水生态文明建设绩效的最大障碍因子;2018~2019年,压力障碍度均值达到24.49%,仍是制约当地水生态文明建设绩效的最大障碍因子;(4)指标层障碍度列在前5位的障碍因子主要分布于压力子系统和状态子系统.综合出现频率和障碍度排序来看,以灌溉水利用系数和万元工业增加值用水量为代表的压力子系统是未来建设中的重点提升方向.本文的研究思路及方法可为类似区域水生态文明建设绩效评价及其障碍因子诊断分析提供理论参考.
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-influenceresponse-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.
