Abstract:
An explicit forest landscape model，LANDIS was used to simulate the impacts of ‘Natural Forest Protection Project’ on the boreal forest of Huzhong forestry bureau in the northern Great Xing’an mountain，China.The potential timber，forest species composition，age structure and spatial pattern index (the Aggregation index，AI；the diversity index，SHDI) was evaluated.The results indicated that the Nature Forest Protection Project would benefit total and most species (except spruce and aspen) potential timber in the mid-long term，and strongly altered the species composition，age structure and spatial pattern.though changes in the total species area were few.Comparing that in the initial simulation，the abundance of birch increased by 6.4%，larch abundance decreased by 12%，and other species abundance such as spruce，zhangzisong，yansong，aspen，popular and willow changed little.Forest age structure also responsed rapidly to the forest management regime，the abundance of unmature standing forest (age≤100 yr) and mature forest repectively decreased by 10% and 24%，and the overmature standing forest (age≥180 yr) increased to 33%.In addition，forest diversity and forest fragmentation would both increase under the current forest management regime.
