对浙江省东部、昆明、海南岛等地的玄武岩母质土壤进行了发生学特性的专门研究。结果表明,玄武岩母质土壤具有强度富铝化的发生学特性,与一向被认为具有显著富铝化程度的第四纪红土母质土壤比较,在粘粒矿物组成、粘粒硅铝率、粘粒硅铝铁率、风化淋溶系数、氧化铁水合系数等方面均高一个量级。这种不同母质土壤间发生学特性的差异幅度与不同纬度带条件下玄武岩母质土壤间的差异幅度基本相同,足见玄武岩母质土壤在发生学方面的特殊性。因此认为,在高级分类中考虑玄武岩母质土壤在发生学方面的特殊性,对减少红壤分类中的混乱可能是有益的。
In the eastern part of Zhejiang Province, Kunming, Hainan Island and other places of basaltic parent soil genetic characteristics of a special study. The results show that the parental basalts have the characteristics of strong aluminiferous mineralization. Compared with the Quaternary red clay parental soil, which has always been considered to have significant aluminum enrichment, Aluminum-iron rate, weathering leaching coefficient, hydration coefficient of iron oxide and so on are one order of magnitude higher. The differences in the occurrence characteristics of the soils of different parental soils are basically the same as that of the basaltic parent soils under different latitudes, which shows the peculiarities of basaltic parent soil in genetics. Therefore, it is considered that consideration of the peculiar genetics of basaltic parent soil in the high taxonomy may be beneficial in reducing the confusion in the classification of red soils.
