Abstract

Forest Vegetation is the important factor on effect of soil physicochemical properties. Therefore, the basis of forest operation is fully to understand the mutual relations between vegetation and soil property. The mountain yellow soil of low mountainous regions was taken as the object in Mabian County, southwest of Sichuan basin margin, compating the Cryptomeria fortunei forest, Alnus cremastogyne forest, bush wood, mixed forest (Cryptomeria fortunei×Alnus cremastogyne) forests and slush's soil nutrient changes with the depth of soil including soil alkali-hydrolysable nitrogen, full phosphorus, full potassium, effective phosphorus, and available potassium. The results showed that the soil nutrient content decreased under the five models of shrub, alder, mixed forest, Cryptomeria fortunei and slush, forest soil nutrient content of 0~15 cm layer was hlgher than that of 15 cm~30 cm, which presented a significant correlation. Therefore, integrated shrubbery, mixed planting and optimum afforestation of nitrogen fixation tree in afforestation will improve soil physical and chemical properties, increase soil nutrient, accelerate the growth of forest vegetation, which is good for ecological circulation.
