Assessment on Comprehensive Ecological Benefit of the Main Coastal Shelterbelt in Pingtan Island
摘要
Abstract
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.关键词
