皖南山地土壤系统分类研究

TAXONOMIC CLASSIFICATION OF SOILS IN THE MOUNTAIN REGIONS IN SOUTH ANHUI

选取皖南四座山地土壤垂直带中 1 9个土壤剖面 ,研究了土壤成土环境和形成特点。根据《中国土壤系统分类 (修订方案 )》和《中国土壤系统分类———理论·方法·实践》 ,鉴定了诊断层和诊断特性 ,确定供试剖面在中国土壤系统分类中的归属。自山下到山上依次为湿润淋溶土 (伴有湿润雏形土 )———常湿淋溶土 (伴有常湿雏形土 )———正常新成土亚纲。与不同分类系统中土壤类别归属作了参比 ,同时也与福建、江西山地土壤作了比较。

Summary This paper deals mainly with soil forming factors and characters of the mountains in South Anhui. According to the “Chinese Soil Taxonomy (Revised proposal)”,and the “Chinese Soil Taxonomy (theory method practice)”, diagnostic horizons, diagnostic characteristics and attribution in soil taxonomic classification of nineteen soil profiles distributed vertically in the mountain regions. Results showed that Udic Luvisols (Udic Cambisols), perudic Luvisols (perudic Cambisols) and orthic Entisols (perudic Cambisols) were distributed in sequence from foot to top. Comparisons were also made with the soils in the mountain regions in Jiangxi and Fujian in terms of attribution in the Chinese Soil Taxonomy and between attribution of the soils in different soil classification systems.
