- 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.
