Research on Natural Regeneration of Quercus Liaotungensis Forest in Qiliyu National Forest Park of Shanxi Province
The forest structure and natural regeneration of Quercus liaotungensis forest in Qiliyu National Forest Park of Shanxi province were studied.The results indicated that the Quercus liaotungensis was still the dominant tree species in the Quercus liaotungensis forest in Qiliyu national forest park of Shanxi Province,and the young trees in the forest were in good condition of regeneration.According to the regeneration density and regeneration frequency,it could be seen that Quercus liaotungensis,Acer pictum and Pinus tabuliformis had better regeneration conditions with higher importance values for their young trees and they occupied an advantageous position in the regeneration competition.The spatial distribution pattern of Quercus liaotungensis,Acer pictum and Betula platyphylla young trees were all clustered,while the young trees of Pinus tabuliformis were randomly distributed in most sample plots.According to the actual survey results,the renewed Quercus li-aotungensis was still in the seedling stage.
