Abstract:

This study evaluates the value of forest ecosystem service function in Guandi Mountain state-owned forest region, aiming to provide a scientific basis and data support for objectively assessing the ecological benefits of the Natural Forest Protection Project, carrying out forest management and ecological benefit compensation, and realizing the value of ecological products. The study is based on the national forestry industry standard Forest Ecosystem Service Function Evaluation Specification (GB/T 38582—2020), and the second-class survey data of forest resources in 2019. The research shows that the total value of forest ecosystem service function in Guandi Mountain state-owned forest region is 21.442 billion yuan. The functions with the largest value are the value of purifying the environment, the value of water conservation and the value of oxygen release, accounting for 81.62% of the total value. Wenyuhe Forest Farm has the largest value of 1.491 billion yuan, and Wucheng Seed Garden has the smallest value of 0.229 billion yuan. Among the main stand types, arbor forest accounts for 85.46% of the total value, and shrubbery accounts for 14.54%. The value order of the main tree species is: Pinus tabulaeformis > Quercus liaotungensis > Larch> Poplar> Birch > Arborvitae> Spruce. Guandi Mountain state-owned forest region has a high value of forest ecosystem service function and plays an important role in the forest ecosystem service function in Shanxi Province. It is recommended to carry out scientific protection and restoration, improve forest quality accurately and monitor ecological benefit continuously, in order to maximize the value of forest ecosystem service function.

Key words: forest ecosystem service function, total value, forest management, Guandi Mountain state-owned forest region
