摘    要:
以永安天宝岩国家级自然保护区内天然柳杉群落调查资料为基础,采用聚集强度指标法、Iwao M·-(x-)的回归与Taylor幂法则对不同海拔天然柳杉群落空间分布格局进行比较分析.结果表明,不同海拔天然柳杉林空间分布格局存在明显差异,其中在1 200~1 600 m与1 000~1 200 m海拔时呈现聚集分布,900~1 000 m为均匀分布.通过对不同海拔不同取样尺度下格局变化进行分析,25 m2取样单元时柳杉种群聚集程度最高.

关 键 词:柳杉  天然林  空间分布格局  聚集度指标  天宝岩自然保护区

Abstract:
Based on the investigation of the Cryptromeria fortunei populations in the Tianbaoyan National Nature Reserve of Yong'an City,the concerntration class index,Iwao M*-x-and Taylor principle were used to research spatial distribution pattern of the Cryptromeria fortunei populations at different altitude levels.The result showed that at the altitude from 1 000 m to 1 200 m and from 1 200 m to 1 600 m,the Cryptromeria fortunei populations performed the pattern of clustering distribution,and at the altitude from ...
Keywords:Cryptomeria fortunei  natural forest  spatial distribution pattern  concentraiton class index  Tianbaoyan Nature Reserve
