Abstract:

In this study,the forest functional areas of Huangtuliangzi forest farm were divided based on the concept of landscape watershed.The logging tasks of different forest types were optimized by using forest simulation optimization system(FSOS) and simulated annealing algorithm.The results showed that the forest functional area of Huangtuliangzi forest farm was divided into soil and water conservation forest functional restoration area,forest park recreational forest area and germplasm resource cultivation area,in which the proportion of soil and water conservation forest functional restoration area was the highest,reaching 95.0%;The main forest types are divided into five types:artificial single-layer Pinus tabulaeformis water conservation forest,Robiniapseudoacacia sprouting water conservation forest,artificial Larix gmelinii and Pinus tabulaeformis mixed water conservation forest,artificial larch water conservation forest,and artificial broad-leaved mixed water conservation forest.The proportion of artificial single-layer Pinus tabulaeformis water conservation forest was the highest,reaching 34.1%,and the proportion of artificial broad-leaved mixed water conservation forest was the lowest,only 0.2%.The annual logging volume optimization results of artificial single-layer Pinus tabulaeformis water conservation forest,Robiniapseudoacacia sprouting water conservation forest,artificial Larix gmelinii and Pinus tabulaeformis mixed water conservation forest,artificial larch water conservation forest and artificial broad-leaved mixed water conservation forest were 3 500 m3,1 200 m3,600 m3,1 000 m3 and 100 m3,respectively.If the logging tasks optimized by FSOS system were strictly followed,the above forest types could achieve sustainable harvest in the next 60 years.The optimization results of five different forest types showed that FSOS system could effectively adapt to complex stand structure,predict stand growth,combine short-term tasks with long-term objectives,and comply with the concept of Innovative Forest Management and Restoration Plan scheme.
