摘　　要： 森林是陆地生态系统的主体,森林生态系统服务功能是森林生态系统与生态过程所形成及所维持人类赖以生存的自然环境条件与效用。文章采用产量—价格法、直接市场法、影子工程法、机会成本法等研究方法,评估了梅州市森林生态系统服务价值。结果表明:梅州市森林生态服务年流量价值180.679×108元,其中年生态价值为177.679×108元,是直接经济价值3.00×108元的59倍,社会价值只有14.89×108元。文章旨在强调森林的生态功能,对梅州市的环境保护和生态建设及森林生态系统的管理具有一定的参考价值。 Forest is one of the most important terrestrial ecosystems on the earth. Forest ecosystem service is to maintain the natural environment and conditions for the effectiveness to the forest ecosystems and ecological processes and formed by human activity. This paper evaluates Meizhou City＇s forest ecosystem services, and the main evaluation methods include market valuation, opportunity cost, shadow price, replace project, travel-cost and so on. As a result, the flow value of Meizhou City＇s forest ecosystem services is 18.07 billion yuan, including annual ecological value which is 17.77 billion yuan, direct economic value 0. 3 billion yuan and social value 1.49 billion yuan. And the ecological value is as 59 times as the direct economic value. It is proved by the above-mentioned results that forest ecosystem can not only provide direct economic value for society, but also provide ecological function with much higher value, and all of these will provide a solid base for study and practice on the environmental protection and ecological construction and management of forest ecosystems.
