摘　　要：从黄河小浪底段河流阶地上古土壤形成过程和形态特征 ,分析证明 ,在距今 30万年以来 ,黄河曾经有两次丰水期 (高水位 ) .同时 ,由于环境的影响 ,其古土壤的形成是在丰水期及流水下切时期 ,因而 ,古土壤层的形成与河流水位、气候环境变化有一定的对应关系 .According to the formation course and morphic characters of ancient soil in Yellow River′s tableland of Xiaolangdi, it has been proved that there were two times of abundant water periods (high level) in Yellow River for the last 300000 years. At the meanwhile, due to environmental influence, ancient soil formed in periods of abundant water and flowing water′s cutdown. Whereas the formation of ancient soil has some corresponding relation with changes of rivers′ level, climate and environment.
