摘　　要：采用直接计算法和替代工程法,对海坛岛木麻黄防护林的生态经济效益进行了评估,重点计算了涵养水源、防风增产、土壤保育、固碳制氧这4个主要的生态经济效益。结果表明:海坛岛木麻黄防护林具有较大的生态经济效益,具体为:涵养水源效益6 980.81万元·a-1,防风增产效益987.71万元·a-1,固碳制氧效益344.99万元·a-1,土壤保育效益173.63万元·a-1。研究结果可作为建立海坛岛木麻黄防护林生态补偿机制的依据。Ecological and economic benefits of Casuarina equisetifolia shelterbelt on Haitan Island were evaluated by method of direct calculation ＆ substitution engineering ;four major ecological ＆ economic benefits （water conserva-tion ,wind production ,soil conservation ,carbon sequestration and oxygen） were calculated .Result shows that ：Cas-uarina equisetifolia shelterbelt on Haitan Island has great ecological ＆ economic benefits ,in particular ：water con-servation benefits being 69 808 100 Yuan a-1 ,windproof yield benefits being 9 877 100 Yuan a-1 ,carbon sequestra-tion ＆ oxygen efficiency being 3 449 900 Yuan a-1 ,soil conservation benefits being 1 736 300 Yuan a-1 .The result of this study can be used as basis of establishing ecological compensation mechanism for Casuarina equisetifolia shelterbelt on Haitan Island .
