二郎山森林土壤类型研究

二郎山属于四川盆地西缘山地,是东、西部气候的重要分界线,其东、西坡土壤类型存在较大差异。东坡以黄壤为基带,向上依次是黄棕壤、棕壤、酸性棕壤或暗棕壤;西坡以黄褐土为基带,向上依次是棕壤、暗棕壤等。两坡土壤殊途同归,最后在山脊汇为漂灰土。文中简述了主要森林土壤类型的特征和特性。

STUDY OF FOREST SOIL TYPES OF ER LONG MOUNTATN

Er Long mountain is located in the west mountainous edge in Sichuan dasin and is the important demarcation of climate of the east and west of Sichuan. The soil types of its east slope are quite different from those of its west slope. On the east slope, yellow soil is the basic strip, then from the low to the upper, the soil types are successively yellow brown soil, brown soil,acid brown soil or dard brown soil and bleached-podzolic soil. On the west slope, yellow-cinnamon soil is the basic soil strip, then fron low to the upper, the soil types are successively brown soil and dark brown soil. And finally, the soils on both slopes converge into bleached-podzolic soil at the ridge. The main characteristics and peculiarities of the soils were discussed briefly in the article
