摘　　要：以山西省七里峪国家森林公园内的辽东栎林为对象,研究了其林分结构以及天然更新情况。结果表明,目前山西省七里峪国家森林公园内辽东栎林的优势树种仍为辽东栎,且林内的幼树更新状况良好。由更新密度和更新频度可知,辽东栎、五角槭、油松的更新状况较好,其幼树重要值较高,在更新竞争中占优势地位。辽东栎、五角槭、白桦幼树的空间分布格局均为聚集分布,油松幼树在多数标准地内为随机分布。根据实际调查情况来看,更新的辽东栎尚处于幼苗阶段。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 liaotungensis was still in the seedling stage.
