以南洞庭湖龙虎山林场次生林群落为研究对象，采用点格局O-ring统计方法，分析了该群落中优势树种青椆和樟树的空间分布特征及树种间的空间关联性。结果表明，林木空间分布格局与空间尺度密切相关，小尺度多呈聚集分布，随尺度增大，聚集度降低；受多种因素影响，青椆种群整体呈聚集分布，但有从聚集向随机过渡的趋势，其小树为强度聚集分布，大树呈轻度聚集或随机分布。而樟树种群整体则呈随机分布，其大树更是趋近于均匀分布；青椆种群的生长总体上与樟树无关，其小树更多的是面临来自种内的激烈竞争，而樟树由于是阳性树种，其小树的生长被大树所抑制，仅上层出现林窗时才可能长成大树。

Based on the secondary forest in Mt.Longhu of the South Dongting Lake and by using the O-ring point pattern statistical method , the spatial distribution patterns of dominant tree species , Cyclobalanopsis myrsinaefolia and Cinnamomum camphora, and spatial connection of different tree species were analyzed.The results showed that the spatial distribution pattern was closely related to spatial scales .Most small scale presented aggregation distribu-tion, and the degree of aggregation decreased with increasing spatial scale .In general , the whole Cyclobalanopsis myrsinaefolia community presented an aggregation distribution because of various factors .However, there was a tran-sition trend from aggregation to random distribution .The young trees presented strong aggregative distribution , while the mature ones showed slight aggregation or random distribution .The Cinnamomum camphora community presented a random distribution with its mature trees showed a uniform distribution .The growth of Cyclobalanopsis myrsinaefolia community was independent to Cinnamomum camphora in general , and its young trees were facing more intraspecific competition .Cinnamomum camphora belonged to positive species and the small trees ’ growth were suppressed by ma-ture ones , with some possibilities to thrive when a gap existed .
