【摘要】：近年来,随着我国城市化进程的不断加快,许多城市已经表现出一系列不健康的症状,如水资源日益匮乏、水质污染严重、空气质量下降、生物物种加速灭绝等,甚至威胁到人类的健康。因此,城市生态系统健康的评价具有十分重要的意义,并已引起高度关注。本文分析归纳了城市生态系统基础理论,综述了城市生态系统健康评价相关的研究进展,从城市生态系统的资源、经济、社会、环境4个方面建立了城市生态系统健康评价的指标体系,确定了城市生态系统健康评价标准和评价等级(病态、不健康、亚健康、较健康、很健康)。运用集对分析模型对2008~2013年晋江市城市生态系统健康状况进行评价,并将集对分析法与物元分析法的评价结果进行对比分析。评价结果表明晋江市2008~2013年城市生态系统均处于较健康等级,健康指数有所提升,但各指标状况发展不均衡。由晋江市未来5年城市生态系统健康状况预测结果得出,晋江市城市生态系统的资源健康指数与社会健康指数呈稳定略有提升的趋势,经济与环境要素以及综合健康指数则呈现为下降趋势。通过对晋江市城市生态系统健康变化状况的分析,研究晋江市城市生态系统的优劣势,得出制约晋江市城市生态系统健康发展的主要因素,并对应提出改善其健康状况的主要对策有:调整产业结构与优化经济增长方式,加强对水资源与水环境的保护、完善公共基础设施建设和进一步加强城市环境综合整治。
[Abstract]:It even threatens human health.Therefore, the evaluation of urban ecosystem health is of great significance and has attracted great attention.In this paper, the basic theory of urban ecosystem is analyzed and summarized, and the research progress related to urban ecosystem health assessment is summarized, from the perspective of resources, economy and society of urban ecosystem,The index system of urban ecosystem health assessment was established in four aspects of environment, and the criteria and grades of urban ecosystem health assessment (sick, unhealthy, sub-health, relatively healthy and very healthy) were determined.The health status of urban ecosystem in Jinjiang city from 2008 to 2013 was evaluated by means of set pair analysis model, and the results of set pair analysis and matter-element analysis were compared and analyzed.The evaluation results showed that the urban ecosystem of Jinjiang city from 2008 to 2013 was in a relatively healthy grade, and the health index was improved, but the development of each index was not balanced.Economic and environmental factors, as well as the comprehensive health index showed a downward trend.
