Forestry production and construction
The forest farm was built in 1977. It was under the jurisdiction of the south central forest farm of Aihui County Forestry Bureau before it was built.

In 1987, with the approval of the provincial forestry department, Shengshan forest farm was designated as the improved variety base of Larix gmelinii and Pinus koraiensis. The former forest farm which mainly focused on timber production was transformed into one which paid equal attention to timber production and improved variety production. It will be approved as a provincial nature reserve in the near future.
Silvicultural production

development direction
First, through the implementation of the national key forest ecological benefit subsidy pilot project, focusing on the protection and improvement of the environment, and aiming at the establishment of a relatively complete forestry ecosystem and a relatively developed forestry industrial system. Second, relying on the advantages of the nature reserve and according to the requirements of the nature reserve, we should vigorously build Korean pine forest and expand the area of Korean pine forest. The state plans to establish moose breeding base in the nature reserve to expand the number of this population.
