| 摘 要： | 文章将舟山群岛新区作为研究对象,以结构、功能、协调这3个基准点为视角,构建舟山群岛新区城市生态系统健康的评价指标体系;运用熵权法进行客观赋权,探讨海岛地区城市生态系统健康的主要影响因素;分析系统各主要因素间彼此的联系和相互关系,评价舟山城市生态系统健康动态,以便进一步提高舟山群岛新区城市生态系统健康水平,优化经济结构,为加强海岛地区生态与环境管理,促进海岛地区经济发展提供决策依据。研究结果表明:近年来,舟山群岛新区城市生态系统健康程度以稳中有升的趋势在不断提高;结构指数有小幅波动,功能指数波动显著,改善明显,其中,城市环境是造成结构指数波动的主要原因。城市文明率较低和可持续性持续走低是城市协调度的主要限制因素。由此,优化资源配置、改善经济结构、持续减排、提升城市环境是确保舟山群岛新区城市生态系统健康水平的关键。

| Abstract: | In this paper,the Zhoushan islands new district was considered as the research object,an urban ecosystem health evaluation index system was built on the three basic viewpoints such as structure,function and coordination,by objectively using the entropy weight method,to explore the main impacting factors of the urban ecosystem health in island area.The mutual contact and relationship between main factors of the system were analyzed to evaluate the dynamic of ecosystem health in Zhoushan city,in order to further improve the level of Zhoushan islands new district urban ecosystem health,optimize the economic structure,and strengthen the management of ecology and environment in island region and promote the economic development for decision making basis.The results showed that in recent years,the level of ecosystem health in Zhoushan islands new district urban was increasingly improving.The structure index slightly fluctuated and the function index fluctuated and improved significantly,among which,the urban environment is the main cause of structure index fluctuation.The low urban civilization rate and falling sustainability were the main limiting factors of urban coordination degree.As a result,optimization of the allocation of resources,improvement of the economic structure,continuously reducing emission,and improving the urban environment are the key ways to ensure the ecosystem health level of Zhoushan islands new district urban. |
