摘  要：
种群生活史特征和空间分布格局对于分析种群演替动态规律、判定种群分布规律和预测种群演化过程及变化趋势均具有重要的理论和现实意义。本文从静态生命表、年龄结构、存活曲线三个方面分析了东灵山地区辽东栎种群的生活史特征。结果表明:物种生物学因素是影响辽东栎种群生存力最主要因素,辽东栎种群静态生命表中生命期望值逐渐降低反映出种群生存力下降的趋势。空间分布格局分析表明辽东栎种群各个径级的个体都属于聚集分布。辽东栎实生苗和萌生苗共存是辽东栎种群适应环境压力和与环境协同进化的结果,表明自然状态下辽东栎种群具有较高的稳定性。由于辽东栎种群的这种较强的稳定性和适应能力,随着辽东栎种群发育整个群落将趋于进展演替,最终形成稳定和充分利用环境资源的顶极群落结构。

摘  要：
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.
