中文摘要：

从城市生态系统健康的内涵出发,选择系统活力、组织力、恢复力、生态服务功能和人群健康状况构建城市健康评价指标体系,并运用模糊数学评价的方法对2000～2008年西宁市城市生态系统健康状况进行评价分析。结果表明：2000～2008年西宁市城市生态系统健康状况总体处于病态水平,但逐年趋向于健康方向发展,人均GDP、城市人口密度、人均绿地面积、生活污水处理率、高等学历数和恩格尔系数是胁迫西宁市城市生态健康的主要因子;预测未来3年西宁市病态和不健康的隶属度将呈下降趋势,而健康和很健康的隶属度将呈上升趋势,西宁市城市生态健康状态将达到亚健康水平。

英文摘要：

Research of ecosystem health is becoming a comprehensive cutting-edge discipline focusing on human activity,socio-economic organizations,the natural systems and human health,which has attracted more and more attention in China since the beginning of the 21st century.Urban ecosystem health assessment is an important direction of development in ecosystem health research,especially in the health of urban living environment,which well runs the city as a community or an eco-system.Based on the connotations of the health assessment of urban ecosystem,five indexes are selected to build an evaluation system,including dynamics,organizational structure,resilience,ecosystem services and the health status of populations.Besides the method of fuzzy mathematical models is applied to analyze and evaluate the health of the urban ecosystem of Xining city from 2000 to 2008.The results show that the health status of the ecosystem of Xining city was mainly at a pathological level and tended to be improving year by year during the nine years.Per capita GDP,urban population density,per capita green area,sewage treatment rate,the Engel＇s coefficient and the number of well-educated people have exerted influence on the healthy development of Xining.It is forecasted that the sick and unhealthy status will have a declining trend in the next three years,while the healthy and very healthy status will have a rising trend,suggesting that the ecosystems of Xining will be further improved.And the health in the three years will be mainly in a sub-health state.In fact,forensic analysis will greatly enrich the health of China＇s urban ecosystem as a case study.It is of great practical significance to monitor urban ecological environmental changes in urban planning.Ecosystem health assessment studies on sustainable development are a contemporary hot spot,and how to accurately predict the status of the future healthy development needs to be further explored.
