摘要
本文对科尔沁沙地的基本特征、形成时代和演变规律进行了分析论证,最后提出了改造利用意见.
The basic characteristics of Horqin sandy land are that sand dunes cover on alluvial plains,fixed and semi-fixed sand dunes are dominant, with few moving ones. Horqin sandy land was formed in the Middle Pleistocene. Thicker loess was deposited in the southern and eastern parts of the sandy land. By the Late Pleistocene, the Horqin sandy land had been experiencing some positive and negative desert processes. Influenced by human activities, Horqin sandy land is going worse. Accordingly, the sandy land should be improved and managed.
