Abstract:

 Based on the “Forest Ecosystem Services Assessment Standards” (LY/T1721-2008) issued by the State Administration of Forestry, the forest ecosystem services of all the national and provincical nature reserves in Yunnan Province were evaluated using the public data issued by the authoritative departments and the technical literature data by published publicly. The matter quantity and value of forest ecosystem reflected in service functions including water conservation, soil conservation, carbon fixing and oxygen releasing, nutrient accumulation, atmospheric environment decontaminating and biodiversity conservation were evaluated. The forest service functions were analyzed from different perspectives such as vegtation types, stand quality, soil types and site conditions as well.The results showed that the total value of these six forest ecosystem services in all the national and provincial nature reserves of Yunnan province were RMB 200.902 billion per year, of which the value of water conservation, soil conservation, carbon fixing and oxygen releasing, nutrient accumulation, atmospheric environment decontaminating and biodiversity conservation, accounted for RMB 53.875 billion, RMB 49.379 billion, RMB 12.209 billion, RMB 1.611 billion, RMB 8.321 billion and RMB 75.507 billion respectively. The annual average forest ecosystem service of nature reserves in Yunnan Province is RMB 123.1 thousand per hectare, which was 2.9 times equivalent to the national average, and 2.4 times to the average level of Yunnan Province.
