| 摘 要： | 研究了四川卧龙自然保护区不同海拔高度的五种植被(常绿阔叶林、落叶阔叶林、针阔混交林、暗针叶林和高山草甸)下的土壤中有机质的含量、组成和性质。主要结果如下。1.各土壤虽然生物气候条件差异悬殊,但其腐殖质均属于富里酸型。2.落叶阔叶林、针阔混交林和暗针叶林下的粗腐殖质也属于富里酸型;红外和紫外光谱说明,它们和“成熟的”腐殖酸有明显的不同。3.土壤有机质含量与土壤物理性质和速效性养分含量有密切的关系。

| Abstract: | The content, composition and properties of the organic matters in soils under different vegetations in Wolong Natural Reserve, Sichaun Province were studied. Main results obtained are summarized as follows.1. Althoughthe the soils are under different bio-climatic conditions, their humus comositions belong to fulvic acid type. 2. Raw humus in the soils under deciduous broadleaved forests, coniferous and broadleaved mined forests and dark coniferous forests belong to fulvic acid type.The infrared spectra and ultraviolet spectra indicate that the raw humus is obviously different from "mature" humus acid. 3. The soil organic matter content is closely interrelated with the physical properties and the available nutrient of the soil. |
