| Abstract: | Comprehensive analysis of out door investigation findings and indoor test data of physical and chemical properties showed that the main properties of the soils on the northern slope of the Qinling Mountain change regularly with the increasing altitude: argillification is getting weaker and weaker, and clay reducing significantly. There are obvious argillic horizons in the middle-low zone on the slope, and no type B horizon in the middle-high zone soil pH value and base saturation decrease from the Wei river valley to the top of the Taibai mountain. It features strong leaching, low Fed, high iron activational degree, low enrichment of aluminium and iron. Soil weathering and development remains in the stage of siallitization. According to the Chinese Soil Taxonomy (Revised Proposal), the soil composition spectrum of the Vertical zones consists of Eum-Orthic Anthrosols (< 750meter)-Hap-Ustic Luvisols (750meter~1400meter)-Hap-Udic Luvisols(1400meter~2500meter) Acid Udic Cambisols(2500meter~3300meter)-Mol-Cryic cambisols (3300meter~3500meter)-Umb-Cryic Cambisols (> 3500meter). |
