象山港生态系统脆弱性及其评价体系构建

     

摘要

Using "exposure-sensitive-adaptation" model,the ecological vulnerability evaluation system of Xiangshangang Bay was established through the analysis and calculation.The vulnerability of Xiangshangang Bay ecosystem is moderate fragile,and the main stress factors are the development of harbor industry and aquaculture activities.The sensitive factors are marine biodiversity index,fish eggs and larvae density.The best adaptation strategies are to improve the environmental protection laws and regulations and management mechanism,strengthen the control of pollutants into the sea,improve the sewage treatment rate,improve citizen's environmental protection awareness and participation degree.%本文利用“暴露-敏感-适应”模型,建立了象山港生态系统脆弱性评价体系,经过分析与计算得出象山港生态系统脆弱性为中等脆弱,影响的主要胁迫因子为临港工业发展和海水养殖活动;系统敏感因子包括海洋生物多样性指数,鱼卵、仔稚鱼密度;最佳适应策略是完善环保法律法规和管理机制、加强入海污染物控制、提高污水处理率、提升公民环保意识和参与程度.
