摘要: 采用“例逐龄级累加法”(RAA)研究了缙云山斑苦竹无性系种群的克隆生长格局动态,以及无性系分株克隆生长型的动态趋势.结果表明,作为复轴型的斑苦竹,其无性系种群随时间进程表现为聚集程度逐渐降低的集群分布格局.在自然条件下,斑苦竹更多地表现出单轴型的繁殖趋势.应用RAA分析植物种群,尤其是竹类植物种群前期的克隆生长格局的动态,结果可靠,具有重要的应用价值.

Abstract: By the method of reverse age-class addition(RAA),the dynamics of clonal growth pattern of Pleioblastus maculata clone population on Mt.Jinyun,Chong qing,Sichuan,China is studied. The results show that as a complex axis type,the degree of clump dispersion pattern of this population is gradully decreased with time.In natural habitat,the populaton is mainly reproduced in single axis way.The RAA technique is worthy and reliable for analysing the dynamics of clonal growth pattern of plant population,and bamboo population in particular.
