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、IwaoM＊-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,其中柳杉种群在1 200~1 600 m与1 000~1 200m海拔时呈现聚集分布,900~1 000 m为均匀分布,分析其原因除了与天然柳杉更新等特性有关外,与人为干扰存在密切关系。

Based on the investigation of the Cryptromeria fortunei populations in the Tianbaoyan National Nature Reserve of Yongan city,the concerntration class index,Iwao M＊- and Taylor principle were used to research spatial distribution pattern of the Cryptromeria fortunei populations at different altitudes.The result showed that,from 1000 to 1200m above sea level（a.s.l）and 1200 to 1600m（a.s.l）,the Cryptromeria fortunei populations performed the pattern of clustering distribution,and it showed uniform distribution from 900 to 1000m（a.s.l）.It was relevant with renewing of the natural Cryptromeria fortunei,and was also closely related with human caused disturbance.
