采用种群生存分析方法，对山西霍山辽东栎林的种群结构和动态进行了研究。结果表明，该地区辽东栎种群属于增长型种群，其种群密度、平均胸径、最大胸径在海拔梯度上均具有鲜明的两段式分布特点；辽东栎在幼苗阶段要经过严格的环境筛选，成体后则随龄级的增加，生存能力逐渐衰退，属于严格的DeeveyⅡ型曲线。

Population structure and dynamic of Quercus liaotungensis in Huoshan mountain of Shanxi Province were analyzed by using population survival analysis.The results showed that Q.liaotungensis populations were growth-ori-ented population in this region.Population density, the mean diameter at breast height ( DBH) and the maximum DBH have two variation range along the altitudinal gradient .Q.Liaotungensis population had a higher environmen-tal resistance at young stage, and it grew stably at mature stage and declined at old stage.The survival curve was typical DeeveyⅡtype.
