[Objective] The weathering intensity of granite red soil profile is closely related to the formation of Benggang
which promotes the development and expansion of Benggang. Studying the mechanism of weathering intensity and physicochemical properties on Benggang can provide a theoretical basis for the scientific prevention and control of granite Benggang. [Methods] The typical Benggang profile of granite red soil areas was selected as the research object
the oxide content and physicochemical properties of different soil layers were measured
and the influence of weathering intensity on the physicochemical properties of granite red soil was analyzed. [Results] (1) The major element oxides in the soil profile were mainly composed of SiO2
Al2O3 and Fe2O3. The weathering crust of granite showed the process of desilication and iron-rich aluminization. The weathering intensity decreased with the increase in the depth of the soil profile
which was in the stage of high weathering. (2) The physical and chemical properties of the soil profile exhibited heterogeneous. The surface layer was characterized by high organic matter
cation exchange capacity
clay content and saturated hydraulic conductivity
with strong cohesiveness and water holding capacity; whereas the lower layer had high sand content
loose structure and strong water permeability. (3) The results of correlation and path analysis indicated that weathering intensity was positively correlated with non-capillary porosity
organic matter
cation exchange capacity
clay content
saturated hydraulic conductivity and boundary water content. Fe2O3 had the strongest comprehensive determinative ability for clay content
sand content and boundary water content. (4) The surface weathering intensity was high
with a high proportion of clay
strong water adsorption capacity
strong cementation between soil particles
and good soil stability. The lower layer had a low of weathering intensity
with low content of cementing materials and boundary water content
poor soil corrosion resistance. When the soil was exposed or subjected to water erosion
it easily collapsed
forming Benggang. [Conclusion] The weathering intensity of soil profile has an impact on the physicochemical properties
which is an important factor to promote the formation of Benggang.
