| 摘 要： | 研究衡山自然保护区不同海拔各类土壤腐殖质含量，组成和结果表明，衡山各类土壤腐殖质含量较丰富，均属富里酸型，ＨＡ／ＦＡ比值一般小于０．４，胡敏酸物质光密度较小，芳构化程度低，但随海拔升高，土壤中腐殖质含量增加，胡敏酸碳占有机碳总量百分率增高，表明海拔升调理我有利于腐殖质的累积，特别是胡敏酸物质的缩合，同类土壤不同植被条件下腐殖质含量、组成和性质也有很大区别，因而，土壤腐殖质组成和性质不但是土壤高级分

| Abstract: | The content,composition and properties of the humus in soils under different vertical zone in Henshan Natural Reserve,Hunan Province were studied.Main results obtained are summarized as follows:From the mountain red soil,yellow red soil,yellow soil to para yellow soil,the content of the humus in soils were higher,their humus composition belong to fulvic acid type,HA/FA<0.4.The content of the humus,humic acid carbon percentage of total organic C and HA/FA ratio in soils gradually increase from mountain foot going upwards.The content,composition and properties of the humus in soils under different vagetation of the soil group are different.Soil humus is index of higher categories and basic categories of soil classification. |
