Abstract: To study the life history characteristics and spatial pattern of plant population is of theoretical and practical significances in analyzing the population’s succession dynamics, judging its distribution pattern, and predicting its evolution process and changing trend. In this paper, the life history characteristics of  Quercus liaotungensis population in Dongling Mountain of Beijing were analyzed from the aspects of static life table, age structure, and survival curve. In the study area, biotic factors were the most important factors affecting the viability of  Q. liaotungensis  population. The gradually decreased expected life value in static life table reflected the declining trend of the viability of the population. The individuals in each size class of the population showed a clustered distribution, and the coexistence of seedlings and stump-sprouts was the results of the adaptation to environmental stress and the co-evolution with the environment, which implied that the population had higher stability under natural conditions. Due to the strong stability and adaptability of  Q. liaotungensis population, the whole community would tend to have a progressive succession with the development of the population, and gradually approach to the climax community with stable structure and making best use of environmental resources.
