乌鲁木齐城市生态系统健康评价模型的研究

A Study on Urban Ecosystem Health Assessment in Urumqi

文章介绍了城市生态系统健康的理论与方法,针对乌鲁木齐市的地理、气候和生态特点,研究了干旱气候城市的生态系统健康评价指标。根据2002-2011年乌鲁木齐市统计数据,利用城市生态系统健康评价模型,分析了乌鲁木齐市近10年城市生态系统健康状况随时间变化趋势。2002-2011年的评价结果表明,乌鲁木齐市近10年的城市生态系统健康状况整体呈好转趋势,但隶属度结果表明好转的速度较慢,乌市的城市生态系统健康状况具有较大的上升潜力与空间。随后针对城市生态系统健康的薄弱环节进行分析,确定乌市城市生态系统水平的制约因素,并提出了具有针对性的调整措施,从而为乌市建设生态城市提供科学依据,为今后干旱地区城市生态系统研究提供参考。

With the changing climate, the deterioration of ecological environment in Urumqi becomes increasingly serious,due to its location in the hinterland of the Eurasian continent. This paper aims to evaluate the urban ecosystem health in Urumqi during the past 10 years. Based on the statistical data of 2002 to 2011, the results show that the health condition of Urumqi is going positively. Although the subordinate degree shows a low recovering speed, the city has huge potential and development space in the ecosystem health recovery. Furthermore, the vulnerable section of Urumqi to ecological risks is identified, and scientific suggestion on the construction of an ecological city is also presented. The information can provide reference for the research of ecosystem health assessment in arid areas.
