本文对低地热带雨林帕南戎邦干达兰自然保护区沿环境梯度的树种分布进行了研究。研究目的在于阐明<s:2>‰~ 10 cm dbh范围内树种分布与土壤pH、湿度、土壤深度、凋落物厚度、光照强度、海拔、坡度、样地距海岸线距离等环境梯度的关系。在4个样带中随机建立125个10x10 m2的样方。结果表明，罗丹尼亚（Rhodamnia cinerea）的存在率最高。典型对应分析（Canonical Correspondence Analysis， CCA）的排序结果表明，树种沿环境因子分布不均匀，特征值为0.387。海拔高度是影响树种分布、土壤湿度和光照强度的最主要环境因子。关键词：典型对应分析；分布；低地热带雨林
The research of tree species distribution along the environmental gradients in Lowland Tropical Rainforest Pananjung Pangandaran Nature Reserve had been conducted. The study aimed to elucidate the relationship between tree species distribution with ≥10 cm dbh and some measured environmental gradients, namely soil pH and moisture, soil depth, litter thickness, light intensity, altitude, slope, and the distance of plot from coastal line. A number of 125 of 10x10 m2 quadrats were established randomly in four transects. The results indicated that Rhodamnia cinerea was the species having the highest presence. Ordination technique using Canonical Correspondence Analysis (CCA) suggested that tree species were less evenly distributed along the measured environmental factors with Eigenvalue 0,387. Altitude was themost important environmental factor affected tree species distribution, soil moisture as well as light intensity.Key words: canonical correspondence analysis, distribution, lowland tropical rainforest, Pananjung Pangandaran
