- Abstract:
-
To analyze characteristics and influencing factors of soil infiltration under different vegetation types in hilly region of Taihang Mountains, soil infiltration processes of different vegetation types were simulated to examine their characteristics and their influencing factors were also explored through double-ring method, correlation analysis and canonical correlation analysis. The results showed that:(1) soil infiltration capability increased in the order:bare-land < grassland < bushwood < bushwood land < arbor and bushwood land, which was higher in 0—10 cm layer than in 10—20 cm layer under different vegetation types, the highest mean value of initial soil infiltration rate(5.96 mm/min)and stable soil infiltration rate(4.76 mm/min)appeared in Platycladus orientalis land; (2) simulated infiltration processes with Philip and Kostiakov models showed that these two models described the infiltration better than Horton model; (3) there was the significant relationship (p < 0.05) between soil permeability index and soil bulk density, total porosity, soil organic matter content, root weight density, root volume density, root average diameter. With respect to the soil infiltration capacity, the most important indicators of soil physical and chemical characteristics and root structure were total porosity and root average diameter, and the canonical correlation coefficients of which were 1.299 and 1.084, respectively.
