| 摘 要： | 采用"倒逐龄级累加法"(RAA)和邻接格子样方法,研究海子坪天然毛竹无性系种群克隆生长格局和无性系分株克隆生长型动态。结果表明:海子坪天然毛竹无性系种群的分布格局为随机分布;无性系分株集群的聚块大小或格局规模为256个单位格子面积,即斑块面积在256 m2以上;格局强度达到2.56;格局纹理为2.52,说明疏密比较明显。 |

| Abstract: | Clonal growth pattern of natural Phyllostachys pubescens population and the clonal growth form of ramets(percentage of ramet with single axis within a clone) in Haiziping were studied by using the method of reverse age class addition(RAA) and contiguous grid plot.The results showed that distribution pattern was random distribution,the size or pattern scale of the clumps composed of individual clone population was in an area of 256 grid units,namely the area of every patch was above 256 m2,the pattern intens... |
| Keywords: | natural Phyllostachys pubescens clone population distribution pattern Haiziping |
