【摘要】 通过对西天目山自然保护区的多年野外调查和土样的分析测定,把该区的土壤划分为3个土纲,6个土类,10个亚类,20个土属。从山脚至山顶土壤的垂直分布是红壤、黄壤(黄红壤)和棕黄壤。在近山脚局部地带还有石灰性土壤的分布。该区的红壤具有弱富铝化特征,与典型红壤相比,在理化性质和矿物组成上不完全相同。高海拔的黄壤和棕黄壤部分因受古红土残留母质的影响变为次生型土壤,其性质与正常发育的土壤有一定的区别,肥力水平也明显不同。更多还原

【Abstract】 Through field survey in the nature reserve of Mt. West Tianmu and analysis of the soil samples collected from this area, the soils could be classified 3 orders, 6 great groups, 10 subgroups and 20 families. From the bottom to top, the vertical distribution of soils was red earth, yellow earth and brown-yellow earth. There were calcareous soils in the partial area of the bottom. The red earth had the characteristics of weaker all-itization, not exactly the same as typical red earth in the physical and chemical properties. Owing to influence of residual parent material of the acient red soil, the yellow earth and brown-yellow earth in area at higher elevation had developed into secondary soils. The properties of the secondary soils were significantly different from those of other soils in the same great group.更多还原
