摘　　要：本文基于VSD概念模型,建立了象山湾生态系统脆弱性评价体系,经过分析计算得出象山湾生态系统脆弱性总体呈现中度脆弱状态,影响的主要胁迫因子为临港工业发展和海水养殖活动;系统敏感因子是海洋生物多样性指数;最佳适应策略是不断完善环保法律法规和管理机制、加强环境整治和加大第三产业的投入力度。通过研究发现,象山湾生态脆弱性的评价对合理开发自然资源,对经济建设中的环境保护都有重要的意义。本文收集了象山湾的自然及社会经济数据,对其生态系统脆弱性进行了评价与分析,以期为合理利用生态资源,在开发建设中保护环境提供理论参考,同时为生态环境整治修复工作和区域可持续发展提供依据。This paper established the vulnerability assessment system of ecosystem in Xiangshan bay based on the concept model of VSD. Through analysis and calculation,it is concluded that the vulnerability of ecosystem in Xiangshan bay is in a moderate degree and the main stress factors are the development of port industry and aquaculture activities.System sensitivity factor is marine biodiversity index. The best adaptation strategy is to continuously improve the environmental protection laws and management mechanism and Strengthen environmental remediation and increase investment in the third industry. The results showed that the assessment of ecological vulnerability in Xiangshan bay is of great significance to the rational exploitation of natural resources and environmental protection in the economic construction. This paper collected the natural and social economic data of Xiangshan bay,evaluated and analysed its Ecosystem vulnerability,in order to provide theoretical reference for the rational use of ecological resources in the development and construction of environmental protection,and provide the basis for ecological restoration work and regional sustainable development.
