摘要
为了提高人们对国有林生态系统价值的认识,合理开发和利用森林资源,制定国有林生态补偿标准,应用生态学和生态经济学原理及方法,对建阳国有林生态系统服务价值进行了定量评价,并从生态系统服务功能的角度分析了建阳国有林生态系统对区域生态安全的影响。结果表明:建阳国有林生态系统8项服务价值总量为14.7924×108元/a。建阳国有林生态系统服务功能的直接经济价值和间接经济价值分别为2.6936×108元/a和12.0988×108元/a,间接经济价值是直接经济价值的4.49倍。在国有林生态系统各项服务功能价值的贡献之中,其大小顺序依次为:保护生物多样性>净化空气>固碳释氧>水土保持>林产品>涵养水源>森林游憩>就业价值;国有林生态系统有着巨大的生态经济效益,在维护区域经济社会稳定和生态安全等方面具有不可替代的作用,但没有充分发挥自身所应具有的生态服务功能。
In order to improve people's awareness of the value of state-owned forest ecosystem, the reasonable development and utilization of forest resources, make state-owned forest ecological compensation standard, based on the theory and methods of ecology and ecological economics, the valuation of the state-owned forest ecosystem services in Jianyang was estimated.

Among contribution of value of all ecosystem services, the order of value was below: protecting biodiversityair quality purifyingC fixation and O2 releasesoil and water conservationtimber productwater storagerecreation and ecotourism employment. State-owned forest ecosystem had great ecological and economic benefits, it played an irreplaceable role in maintenance of regional economic and social stability and ecological security etc, however, the ecosystem service functions had not fully utilized.
