摘　　要：基于平潭岛沿海防护林实地观测数据,以改良土壤、固碳释氧、调节气候和水源涵养为准则层,以降低风速、固碳量、土壤容重等10项测定数据为指标层,建立沿海防护林综合生态效益评价体系和评价模型。应用层次分析法(AHP)原理对平潭岛木麻黄、黑松、湿地松、台湾相思4个主要防护林树种的综合生态效益进行评价。结果表明,4个防护林树种均有较强的生态防护功能,但各树种综合生态效益差异明显,综合生态效益指数排序为木麻黄>湿地松>黑松>台湾相思。此研究结果将为平潭岛沿海防护林工程规划、布局、树种选择等提供理论依据。Based on the data collected from coastal shelterbelt field in Pingtan Island,index system and evalu-ation model for the assessment of comprehensive ecological benefit was established,which consists of criterion layer （soil improvement,carbon fixation and oxygen release,climate regulation and water and soil conservation）and in-dicator layer （reducing wind speed,fixed carbon content,soil bulk density and etc.more than 10 indicators）.An-alytical Hierarchy Process （AHP）method was used to evaluate comprehensive ecological benefits of Casuarina eq-uisetifolia ,Pinus thunbergii,Pinus elliottii and Acacia confuse.The result indicated that four kinds of windbreaks have a large eco-efficiency,the order of ecological benefits index is Casuarina equisetifolia〉Pinus elliottii〉Pinus thunbergii〉Acacia confuse.Therefore some scientific suggestions were put forwarded in this paper and which pro-vided basic foundation for planning,overall arrangement,species selection for coastal shelterbelt project in Pingtan Island.
