The four age group types of 2 445. 33 hectares of forest resources of Cenxi zhonglin Forestry Development Co . , Ltd. were selected as the research object, and the basic data of its 2021 forest resources planning and design survey were used to evaluate its ecosystem service value from 13indicators in six aspects, including carbon fixation and oxygen re- lease, water conservation, air purification, sterilization, soil conservation, and biodiversity protection . The results showed that the total value of 2445. 33hectares of forest resource ecosystem services is as high as 116million yuan, of which the total value of carbon fixation and oxygen release was 33. 494 6 million yuan, the total value of water conservation was 13. 0949 million yuan, the total value of air purification was 10. 774 7 million yuan, the total value of sterilization was 723800yuan, the total value of soil conservation was 32. 96million yuan, and the total value of biodiversity protection was 24. 4535 million yuan;Among the four age group types, the total ecological value of the middle aged forest was 46. 1222 million yuan, the total ecological value of the young forest was 29. 2169million yuan, the total ecological value of the near mature forest was 27. 2609 million yuan, and the total ecological value of the mature forest was 12. 901 4 million yuan . The ecological value of each age group forest is positively related to its area and stock. The results of this ecological value accounting provide a reference for the realization mechanism of local forest ecological value and the sustainable develop- ment of forestry.
