| 摘 要： | 黔稠、榕叶冬青和青冈是猫儿山植物群落中分布相对广泛的3个优势种。对它们在不同海拔上的径级结构分析结果表明:3个物种在2个海拔梯度上径级都呈现峰型分布，最高峰都集中在4～8 cm的中小径级范围内，中小个体储备充足，会在相当长一段时间内保持其在群落中的优势地位。通过连续取样的L方程点格局分析方法，对其空间格局和种间关系分析显示:3个物种在样地中不同尺度上以空间显著聚集分布为主，在极少数尺度上仍然存在随机分布和均匀分布格局。3个物种在50 m范围内的分布几乎都表现为独立不相关性。而黔稠和青冈同属于青冈属，在2个样地中的一些小尺度上表现为显著的正相关性。

| Abstract: | Cyclobalanopsis stewardiana,Ilex ficoidea and C.glauca were three dominant species relatively broadly distributed in Maoershan Mountain,Guangxi of southern China.At different altitudes,size distribution of three species individuals showed a unimodal type,and the peak of three species’ DBH all centralized at 4-8 cm class.DBH structures showed that three species had enough junior individuals,meaning they will continuously play dominant role in community for a long time.Based on continuous sampling data for L-function analyses,comparing spatial distribution and species association of three species,we found that three species were significantly aggregated and distributed on several scales,and only a few scales showed random and regular distributions.Associations among three species all showed an independent distribution pattern within 50 m in two plots.C.stewardiana and C.glauca belong to congeneric species and they show a positive correlation on small scales in both plots. |
