【摘要】 本文研究了亚热带几种土壤(黄棕壤、黄褐土、红壤、棕红壤、灰潮土等)剖面磁化率和有机质的相关性。发现:土壤磁化率剖面受纬度、土壤母质磁性本底、气候条件、土壤熟化度,及发育度、土壤颗粒等因子的影响。还发现:红壤和棕红壤、灰潮土、黄棕壤和黄褐土的磁化率与有机质之间正直线相关关系显显程度分别为极显著、显著和不显著。更多还原

【Abstract】 The.correlation was studied of the magnetic susceptibility and organic matte in yellow—brown earth,yellow cinnamon soil,red earth,brown—red earth,fluviogenic soil.It was observed that the magnetic susceptibility profile in soils related to the latitude,magnetic base of the parent materials,climatic condition,soil pedogenesis and ripening.A high significant,significant,no significant postive linear correlation were found between magnetic susceptibility and organic matter in red and brown—red earth, fluviogenic soil,and yellow—brown earth and yellow cinnamon soil,respectively.更多还原
