摘要
通过对开县境内4个典型崖柏种群空间分布格局进行初步研究,表明崖柏种群为明显的集群分布,在取样尺度较小时(群落Ⅰ、Ⅲ、Ⅳ为4 m2;群落Ⅱ为6 m2)集群强度最大,且随着取样尺度的扩大聚集强度逐渐减小。在各群落中集群强度以多齿长尾槭-崖柏群落(Ⅰ)最大,依次为崖柏-铁杉群落(Ⅱ),崖柏-巴东栎群落(Ⅲ),崖柏-黄杨群落(Ⅳ)最小。在对崖柏初步研究的基础上还提出了进一步研究的方向。
This paper focuses on the spatial pattern and dynamics of Thuja sutehuenensis population which distributes in Kaixian County. The main study results were as follows：the population pattern of T. sutchuenensis turned out to be manifestly contagious distribution. On the small sampling scale （ community Ⅰ ,Ⅲ, Ⅳ is 4 m^2 ; Ⅱ is 6 m^2） , the contagious degree was higher than other scales. And with the extention of the sampling scale,the degree of contagition got lower and lower. As for the contagious degrees of four different communities, the order was A. caudaturn var. rnultiserraturn - T. sutchuenensis community （ Ⅰ ） 〉 T. sutchuenensis - T. chinensis community （ Ⅱ ） 〉 T. sutchuenensis - Q. engleriana community （ Ⅲ ） 〉 T. sutchuenensis - B. sinica community （ Ⅳ ）. The future research direction and content are also advised in this paper.
