矮牡丹( Paeonia suffruticosa Andr.var.spontanea Rehd .) 无性系分株种群结构的研究结果表明:7 个样地矮牡丹的年龄结构可划分为 4 类:强增长型、 平缓增长型 、 稳定适应型和波动型, 前 3 类种群的数量动态符合负指数方程 y =e^a-bx 。 表现结构为单株高度不超过 120 cm, 基径不超过 2 cm。 适宜生境为地带性顶极群落辽东栎林。
 

There are four types for age structure of Paeonia suffruticosa Andr.var.spontanea Rehd. population: swift increasing type, gently increasing type, stable and adapted type and unstable type. The population quantity trends of the former three types can be described by y = e^a-bx . The tallest plant is inferior to 120 cm and the basal diameter 2 cm. Quercus liaotungensis Koidz. forest is the most suitable community for P . suffruticosa var. spontanea .
