中文摘要：

海岸带位于海陆系统交错地带,独特的区位特征使其生态风险评价既有区域生态风险评价的综合性,亦有自身的特殊性。近年来,随着沿海经济发展和海岸带生态环境的恶化,海岸带生态风险越来越受到关注,但尚缺乏有关海岸带生态风险评价深入系统的研究与总结。通过梳理和归纳现有研究成果,基于海陆相互作用和陆海统筹的思想,在充分考虑海岸带生态环境的独特性、地域性和综合性的基础上,从风险源—生境—风险受体三大基本要素对海岸带生态风险评价概念及其组分进行了科学界定,并从风险源与驱动力、风险受体与评价终点、综合评价等视角详细阐释了目前海岸带生态风险评价研究的相关主题、发展脉络和主要论点;在分析海岸带生态风险评价的特征、已有模型和方法的基础上,解析了海岸带生态风险评价的理论架构。最后分析现有研究的不足,展望未来研究趋向,为今后海岸带生态风险评价研究提供思路与参考。

英文摘要：

Coastal areas are located in marine-terrestrial interlaced zone. With their unique geographical positions,the coastal ecological risk assessment has both the complexity of regional ecological risk assessment and its own particularity. In recent years,due to the coastal economic development and the deterioration of ecological environment,coastal ecological risk has received more and more attention,but there are still lacking in further systematic study about the coastal ecological risk assessment. With the summary and analysis of the existing research results from home and abroad,based on land-ocean interaction plan and full consideration of the uniqueness,regionalism and complexity of the coastal zone environment,this paper made scientific conclusion on the definition of the coastal ecological risk assessment concept and its components from risk source,habitat and risk suffer-the three basic elements. Moreover,from risk source,risk suffer and comprehensive evaluation-the three aspects,it discussed in detail the related research topics,progress as well as main conclusions. Then,it analysed the characteristics and evaluation methods,and put forward the framework model of coastal ecological risk assessment. Finally,it analysed and proposed the existing deficiencies and future research direction,providing new ideas for future research on coastal ecological risk assessment.
