摘要
缙云山不同植被下黄壤的研究表明,不同植被类型下黄壤的腐殖质组成及发生学性质不同,并有一定规律:从针叶林地→针阔混交林地→常绿阔叶林地,腐殖质含量增加,腐殖质物质系统趋于复杂化,土壤酸度、粘粒含量及游离铁含量亦顺次增加.本文从两个方面对以上结果进行了讨论:(1)现状植被对腐殖质组成的影响.(2)植被演替对土壤腐殖质组成及发生学性质的影响.并将土壤腐殖质组分与粘粒含量、氧化铁的游离度综合考虑,对土壤腐殖质各组分的组合情况与土壤个体发育阶段间的关系进行了初探.
This paper is a report on yellow soil under various plants communities on Jinyun Mountain Nature Reserve. The results are shown:Yellow soil humic compositions and genesis features under various vegetation types are different and. demonstrate some regular partterns. From evergreen needle forest→evergreen needle-evergreen broadleaved forest→evcrgreen broadleaved forest, hurnic matter content increases, humic matter system is tending towards complexion, soil acidity, clay content and free iron content increase too. in this paper, the relationship between present vegetation and soil and the reationship between soil individual development and vegetation succession are discussed.
