The Spatial Distribution Pattern of Umbrella Bamboo ( Fargesia robusta ) Clones
摘要
Abstract
Umbrella bamboo (Fargesia robusta) is one of the major species of bamboos on which giant pandas feed in Wolong Nature Reserve. In this article, studies were made of the distribution pattern of umbrella bamboo clones by using a t test of Dispersal Index ( c), F test of Morisita's Index ( I), Negative Binomial index (K), Lloyd's Index (m) and Patch Area Index (PAI) across different block sizes. Analysis was also made of clumping intensity of umbrella bamboo clones in different block sizes by using Negative Binomial Index, Lloyd's Index and Patch Area Index. Then the average distance was computed be- tween different age classes of umbrella bamboo ramets by using GIS software, and the relationship was an- alyzed between age and distribution of umbrella bamboo ramets. The results indicated that:(1) umbrella bamboo clones were distributed in a clumped pattern, (2) the clumping intensity of umbrella bamboo clones decreased with increasing block size, (3) the average distance between different age classes of umbrella bamboo ramets increased with increasing age gap.关键词
