摘　　要：为了研究亚热带自然保护区森林生态系统服务功能的价值,选取森林生态系统典型、保存完好的八大公山自然保护区作为研究区域,运用市场价值、影子工程和机会成本等方法,得出八大公山自然保护区森林生态系统7项生态服务价值总量为183 625.6万元/a,其贡献大小顺序依次为:涵养水源>保护生物多样性>固碳释氧>生产有机物质>净化空气>森林游憩>土壤保持;涵养水源价值居第1位,占总价值的36.49%;其次为保护生物多样性的价值,占总价值的29.87%;固碳释氧价值占15.05%,前3项合计占81.41%。森林生态系统服务在价值构成上出现这种比重与国内大多数研究结果基本一致,主要在于该自然保护区处于水系源头,加之受人为活动干扰较小,森林生态系统发挥了巨大的生态效益。对该区森林生态系统服务功能价值进行定量评估,有助于加深人们对森林生态效益在价值量上的认识,进而更好地保护森林资源。The values of service functions of forest ecosystem in Badagong Mountain Nature Reserve were evaluated by adopting the methods of market value, shadow engineering, opportunity cost and others. The total value of 7 forest ecosystem services in Badagong Mountain Nature Reserve was 183 625.6 ×10^4 yuan per year. The service functions sequenced by magnitude as follows： water storage, biodiversity protection, assimilation of CO2 and O2 release, the production of organic, all purification, forest recreation, eeo-tourism and erosion control. The value of water conservation ranked No. 1, accounting for 36.49% of the total value, the value of biodiversity protection took the second place, accounting for 29.87%, CO2 and O2 release took the third place, and the three together stood at 81.41% in the whole list. The value constitution of its forest ecosystem was quite consistent from that of the other places in China. The main reason was that the nature reserve located in the source of river system, suffered from less interference by human, so the forest ecosystems played a significant ecological benefit.
