摘要:
城市生态系统健康评价是制定城市规划、建设、管理政策的依据。结合石家庄实际情况，选取活力、组织力、恢复力、生态系统服务功能和人群健康状况构建城市生态系统健康评价指标体系。基于均方差法确定指标权重，运用模糊数学评价方法对2005-2009年石家庄城市生态系统健康进行了评价分析。结果表明：石家庄城市生态系统健康状况由2005-2007年的亚健康水平提升到2008-2009年的较健康水平。其中有利因素为组织结构、恢复力、生态系统服务功能，不利因素为活力与人群健康。主要胁迫因子为人均生活用水量、实际利用外资、万元GDP能耗、R&D经费比重、环保投资占GDP比重、居民人均收入、高层次人才比重。最后，提出了提升城市生态系统健康水平的建议。
Abstract:
Urban ecosystem health assessment is the basis of making city planning, construction and management policy. According to the actual status of Shijiazhuang City, five indices were selected to build up an evaluation system, including dynamics, organizational structure, resilience, ecosystem service function and population health. Fuzzy mathematical models were employed to analyze and evaluate the healthy state of Shijiazhuang urban ecosystem from 2005 to 2009 based on the method of mean-squared deviation to determine index weight. Results showed that the healthy state of Shijiazhuang ecosystem was changed from sub-healthy level on 2005-2007 to healthy level on 2008-2009. The favorable factors affecting urban ecosystem healthy state of Shijiazhuang included organizational structure, resilience and ecosystem service function, while unfavorable factors included dynamics and population health. Main stress factors to healthy development were per capita water consumption, foreign capital actually utilized, 10 thousands Yuan GDP energy consumptions, proportion of R&D funding, proportion of environmental protection investment in GDP, per capita income and proportion of high-education people. Finally, some suggestions were proposed to improve urban ecosystem healthy level.
