Abstract: According to the theory of J.L.Harper's (1977)modular organism, considering the assemblage of Pleioblastus maculata in the habitat as a clone population, the dynamics of clonal propagative modules and the modules with age class genet of and density of ramets were studied in this paper.These results show as follows:The number of Propagative modules that Ⅲ age class genets produce them is the largest, after this, it is gradully falling with the increase of age class.These numbers of appeared, death and mature of bamboo shoot all are interrelated to the density of ramets in the clone population the correlation density of the largest valuws in al 2.5×104 bamboo modules/ha.There is line correlationship between the numbers of death and mature of bamboo shoot and time of ap-peared bamboo shoot, the regression models as below:model of death ratio:D=27.253+0.702t(R2=0.636) model of mature ratio:M=72.662-0.701t(R2=0.634)

Key words: Pleioblastus maculata, clone population, clonal propagative module, dynamic, regulation
