Forest ecosystem services and its value have been given more attention,it is need of society sustainable development to estimate forest ecosystem and bring it into domestic economy evaluation. Based on remote sensing data and field survey,combined with ecological values index, the tropical forest ecosystem value in the natural reserve of Hainan Island was estimated. The results indicated that the service value of ecosystem induced by tropical natural forest protecting projects in Hainan Province would be more than twice of the investment during 2000～2010. So,natural forst protecting project of Hainan Island is an item with low investment and high income.%森林生态系统服务功能及价值越来越受到人们的重视,对森林进行保护并对其估值将其纳入国民经济核算体系是社会可持续发展的需要.以遥感数据结合地面调查数据对热带森林进行分类,参照现有的热带森林各项生态价值指标对海南省天然林保护工程实施的效果进行估算和评价.结果表明,以2000至2010年的保护期计算,生态系统服务效益产出投入比在2倍以上.海南省热带天然林保护工程的实施,直接产生的生态系统服务价值增量及保护产生的损失替换价值远远高于保护工程的投入,是一项低投入高效益的项目.
