Structure dynamics and quantitative statistics of clone plant population are two basic characteristics of populations. The demography of natural Phyllostachys edulis clone population in Haiziping was studied by using life table and surviving curve, and the method of age estimation of ramet was also discussed. The results demonstrated that: ( 1 ) In natural Ph. edulis clone population, the general tendency of age structure presented as that proportion of ramet decreases gradually with the increasing of age of ramet. (2) The survivorship cur...
