摘　　要：基于森林资源二类调查与森林生态系统定位观测数据,综合运用生态学、水土保持学、经济学理论方法,采用分布式测算方法,依据森林生态系统服务功能评估规范,选取符合天然林生态系统的6项服务功能9个指标,对陕西省宁陕县天然林保护工程的生态效益进行了评估。结果表明:陕西省宁陕县天然林保护工程生态效益总价值为115.36亿元·a^(-1)。不同生态系统服务功能项中,生物多样性保护、固碳释氧和涵养水源3项功能价值量最大,分别占陕西省宁陕县天然林保护工程生态效益总价值的44.10%、32.08%和19.62%。说明陕西省宁陕县森林在生物多样性保护、固碳释氧和涵养水源方面都发挥着重要的作用。Based on the combination data of the class II investigation to forest resource and fixed observation to ecological factors, the integrated theory of ecology, water and soil conservation and economics, and the method of distributed modeling, we evaluated the values on ecological benefits of the Natural Forest Protec- tion Project in Ningshan County within Shaanxi in terms of 6 kinds of ecological services functions （9 indi- ces） according to specifications for assessment of forest ecosystem services in China. The results showed that the annual value on ecological benefits of the Natural Forest Protection Project in Ningshan County within Shaanxi was 11. 536 billion Yuan RMB. For different ecosystem services, the values of biodiversity protection function,CO2 fixation and O2 generation function and water conservation function were the high- est and accounted for 44.10% ,32.08% and 19.62% of the total,respectively. These suggested that biodi- versity conservation, water conservation and the CO2 fixation and O2 generation played very important roles.
