【摘要】 对北亚热带中部黄土母质发育的9个土壤剖面的化学特性、物质转化规律、粘粒的迁移淀积特征、粘土矿物组成以及微形态特征等进行了研究。结果表明:因受该区生物气候条件和母质本身特性的影响,土壤经受了较为强烈的风化淋溶作用。具有比较一致的成土过程,土壤具有明显的粘化特征。兼有淀积粘化和残积粘化过程以及弱富铝化过程.并带有明显的母质残留特点。更多还原

【Abstract】 Studies on characteristics of chemistry, material transform, clay migration and illuviation, clay mineral components, and micromorphology were made with nine soils derived from Xiashu locses in the northern subtropical region of China. Rcsults obtained were as follows:Under the influences of parant material features and the soil forming conditions, 1) the intensity of the soil weathering and eluviation is stronger; 2) the soil forming processes are similar, which include the processes of illuvial clayization, residual clayization and lighter allitic weathering; and which show the transitional characterisitcs between the soil allitic process in tropical zone and the soil brown earthening process in temperate zone.更多还原
