Abstract:

Forests managed by Lushuihe Forestry Bureau were taken as a case to analyze relative influences of harvest parameters, such as cutblock size, the spatial dispersion pattern of harvest units, whether or not reserving the forest adjacency to young forest and rotation length, on forest landscape pattern. The Harvest model and neutral landscape model were used to simulate various harvest strategies. And the Apack software was used to calculate landscape indexes of the simulated results for determining the degree of influence. The results showed that big cutblock size, clustered cutblocks, reserved forests adjacent to young forests and long rotation were able to reduce degree of forest landscape fragmentation in harvest. Whether or not the forest adjacent to young forests was reserved had the greatest influence on forest landscape, and cutblock size had the second of that.

Key words: forest harvesting, harvest factors, landscape pattern, Harvest simulation model, neutral landscape model, Apack software, Lushuihe Forestry Bureau
