摘　　要： 采用TW INSPAN进行植被类型分类,对广东长潭自然保护区不同植被类型土壤有机碳分布特征进行了研究,结果表明,基于乔木胸高断面积作为分类标准的不同植被类型土壤有机碳差异极显著(p<0.01),8个植被类型中,胸高断面积最小的植被类型3土壤有机碳含量最高,为27.45±1.41 g.kg-1,胸高断面积最大的植被类型1土壤有机碳含量最低,为11.87±2.69 g.kg-1,总体呈胸高断面积增加土壤有机碳含量减少的趋势。 SOC contents is the main characteristic of forest soil fertility, so studying SOC contents of different vegetation types has important actual meaning, This study used TWINSPAN to sort vegetation types, studied SOC distribution characteristic of different vegetation types in Changtan Nature Reserve, Guangdong province. The result showed, prominent difference of SOC content of different vegetation types basing on arbor basal area was existed（p 〈 0.01 ）, among 8 vegetation types, having the most SOC content was typel which had the least basal area, SOC contents was 27.45 ± 1.41 g · kg^-1, having the least SOC content was type3 which had the most basal area, SOC contents was 11.87 ± 2.69 g · kg^-1. Generally, SOC contents decreased with basal area increasing.
