摘要
矮牡丹 (PaeoniasuffruticosaAndr.var.spontaneaRehd .)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 =ea -bx。表现结构为单株高度不超过 12 0cm ,基径不超过 2cm。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.
