摘　　要：了解海南长臂猿栖息地不同植被群系植物的多样性,对海南长臂猿的种群恢复和发展具有重要意义。研究以海南长臂猿C群和E群的栖息地为对象,调查和分析栖息地植物群落多样性、径阶分布、空间分布格局以及种间关联。结果表明:C群和E群栖息地优势种乔木植株分别共计250株和370株。C群和E群栖息地直径大于10cm植物个体分别为874株和864株,其乔木群落优势种径阶分布个体数量最多的均在10cm~20cm区间。C群和E群栖息地中不同种群随尺度不同呈现出集群分布或随机分布。种间关联方面,C群栖息地公孙锥种群与其他树种在0~20m尺度上均无显著相关性;E群栖息地枫香树种群与其他树种在大尺度上以负相关为主。研究结果以期为海南长臂猿栖息地保护和猿食性植物的多样性提供基础数据。Understanding the plant diversity in the habitats of Nomascus hainanus is of great importance for the recovery and development of the species.This study took the habitats of Nomascus hainanus C and E groups as the object,analyzing the plant community diversity,diameter class distribution,spatial distribution patterns,and interspecific associations.The results showed that:the dominant tree species in the group C and E habitats totaled 250 and 370,respectively.There were 874 and 864 plant individuals with a diameter of more than 10 cm in group C and E habitats,respectively.Diameter class distribution showed that most individuals of the dominant tree species in both habitats were in the 10~20 cm interval.The spatial distribution pattern showed that the different plant populations in group C and E habitats were either clustered or randomly distributed depending on the scale.In terms of interspecific association,the Castanopsis tonkinensis population in the group C habitat had no significant correlation with other tree species at the scale of 0~20m;the interspecific association of Liquidambar formosana population in the E group habitat with other tree species was mainly negative at the large scale.The research is expected to provide basic data for the protection of Nomascus hainanus habitats and the diversity of their food plants.
