摘　　要：研究广西涠洲岛和斜阳岛沉凝灰岩母质发育自然土壤和旱地土壤的基本属性,参考《中国土壤系统分类(首次方案)》进行分类,分布于涠洲岛火山口附近的土壤属于薄层土土类,其它土壤属于湿润铁硅铝土亚纲的棕红壤;斜阳岛上的土壤为火山灰土。The basical specificities of the arid land soils and natural soils which develop from sedimentary tuff on Weizhou and Xieyang islands of Guangxi are studied, and the soils are classified in accordance with the classification indexes of Chinese Soil Taxonomic Classification(1st proposal). The soil around the volcanic mouth of Weizhou island belongs to the group of Leptisols, and the others are brown-red soil which bdongs to the suborder of Udic fersiallisols. The soils on Xieyang island are Andisols.
