基于熵权的海岛地区城市生态系统健康动态评价研究——以舟山群岛新区为例
Urban Ecosystem Health Evaluation of the Dynamic Island Area Based on the Entropy Weight Method:A Case Study of Zhoushan Islands
摘要
Abstract
In this paper,the Zhoushan islands new district was considered as the research obj ect, an urban ecosystem health evaluation index system was built on the three basic viewpoints such as structure,function and coordination,by obj ectively 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 ecosys-tem 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 ecol-ogy 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 alloca-tion of resources,improvement of the economic structure,continuously reducing emission,and im-proving the urban environment are the key ways to ensure the ecosystem health level of Zhoushan islands new district urban.关键词
