濒危植物南川升麻种群数量动态的分析

Cimicifuga nanchuanensis is an endangered plant species, only distributed in Jinfu Mountain, Sichuan Province, China. At present, there exists a population. Based on overall investigation of age structure, seed production and seed natural germination rate etc, the numeric dynamics of Cimicifuga nanchuanensis population was studied by application of static life table, fecundity schedule and Leslie matrix. The results were as follows: Its net reproductive rate ( R 0 ), intrinsic rate of increase ( r m ) ...
