摘要: 本文以广西南宁盆地那桐风化壳,及百色盆地江泽风地壳的大量土体化学分析数据为依据,进行了第四纪红土的确认、形成、分布和土壤肥力状况。以及通过地球化学强度、硅铁系数、硅铝系数等指标进行了两风化壳的对比研究。同时,还探讨了风化壳的发育过程及其与环境的关系。

关键词: 南宁, 百色, 红土风化壳, 地球化学, 环境

Abstract: Based on a great amount of chemical analytical data of the Natong weathering redearth curst in the Nanning basin and the Jiangze Weathering redearth Curst in the Baise basin in the Zhuang Autonomous Region of Guangxi,this paper carried out a comparative research on the confirmation,formation,distribution and soil fertility of the Quatarnary redearth and the characteristics of the two weathering cursts by using the indices got from the intensity of geochemistry and the coeffients of silica ferrite and silica alumina, and discussed the developmental process of the weathering curst and its impact on the environment.

Key words: Nanning and Baise basins, Geochemical Characteristics, Redearth crusts, Environmental significance
