【Abstract】 Based on the monitoring data of forest resource benefit,long-term positioning observation data of forest ecological system,investigation data of forest resource and public data from the authorities,and evaluation model of forest ecosystem service function,the forest ecosystem service function in Menyuan county in 2013 was evaluated and the value was 29. 362 8 billion yuan / year. The values of the ecosystem services were in the following order: soil conservation,biological diversity protection,water conservation,purify environment,carbon fixing and oxygen releasing,forest protection,forest recreation and accumulation nutrients.
