摘　　要：辽东栎（Quercus liaotungensis）隶属于壳斗科（Fagaceae）栎属（Quercus）,是我国暖温带极为重要的森林建群种,以及我国暖温带落叶阔叶林的主要优势种之一和华北针阔混交林的主要成分;在暖温带主要分布在河南、The floristic character,community appearance,community structure and species biodiversity of Quercus liaotungensis communities in Lingkong Mountain area were studied to explore adaptive characters of the communities by using the plot investigation methodology.The result showed that the Q.liaotungensis communities in Lingkong Mountain area consisted of around 182 species,displaying an apparent temperate characteristic.The phaenerophyte was of absolute dominance in the life form spectra,which bore the typical appearance characteristics of the warm temperate deciduous broadleaf forest.Although the community structures were stable in different Q.liaotungensis communites,but reserve of seedlings of Q.liaotungensis population was insufficient.The species biodiversity index value varied and fluctuated in different communities and layers,however,pure Q.liaotungensie forests were relatively stable.Based on the thorough studies of different Q.liaotungensis communities in the Lingkong Mountain area,the adaptabilities and the internal mechanisms of Q.liaotungensis communities in the warm temperate zone were illustrated,which provided a scientific foundation for the protection and expansion of the germplasm resources and the sustainable management of Q.liaotungensis.
