通过对毛乌素沙漠东南部保宁布剖面的粒度分析，探讨了毛乌素沙漠历史沙漠化的过程和原因，结果表明，毛乌素沙漠经历了唐中后期和明末两个阶段的沙漠化过程。这两个阶段的沙漠化使毛乌素沙漠的环境严重恶化，特别是第二阶段，形成了毛乌素沙漠现在的景观。沙漠化的两个阶段都得到了历史记载和考古资料的证实，因此结果是高度可靠的。通过气候变化的对比，认为明末的沙漠化与人类活动密切相关。
Based on the grain size analysis of the Baoningbu(BNB) section situated in the south-east of the Mu Us Desert,the authors investigated the processes and the causes of historical desertification of the desert.The results indicate that two phases of desertification,namely at the mid-to-end Tang Dynasty and at the end of the Ming Dynasty,are documented by the section.The two phases of desertification greatly made the environment of the Mu Us Desert deteriorate,especially for the second one,which formed the present landscape of the Mu Us Desert.The two phases of desertification are corroborated by historical records and archaeological data.Therefore the results are highly reliable.With a comparison of climate change,we suggest that the desertification occurring at the end of the Ming Dynasty was highly related to the human activities.
