中文摘要贡嘎山东坡寒区林地在海拔2200~3650m的典型土壤,其土壤诊断层和诊断特性主要有暗瘠表层、漂白层、雏形层、石质接触面特征、常湿润土壤水分状况和寒冻、寒性、冷性或温性土壤温度状况.由于泥石流和冰川堆积物对所发育土壤性状有很大影响,提出了划分泥石流岩性特征和冰碛物岩性特征及其诊断指标.根据本区土壤诊断层和诊断特性,按照中国土壤系统分类对研究区典型土壤进行了检索,在分类中首次根据泥石流岩性特征和冰碛物岩性特进行了土壤系统分类.
英文摘要 Representative types of soils in forestry regions ranging from {2 200} m to {3 650 m a.s.l}. on the east slopes of the Gongga Mountain they were classified based on soil taxonomic classification. The main diagnostic horizons and diagnostic characteristics are umbric epipedon, albic horizon, cambic horizon, lithic contact, perudic soil moisture regime, and gelic, or cryic, or frigid or mesic soil temperature regime. Lithologic and diagnostic indices of debris flow deposit and till were proposed, because debris flow deposit and till greatly affect soil properties in this region. Searches of representative soils were done by the Chinese Soil Taxonomy in accordance with the diagnostic horizons and diagnostic characteristics of soils in the region. It is the first soil classification based on the lithologic characteristics of debris flow deposit and till.
