	3.	Situated at the southeast of the mu us desert , ordos plateau , the milanggouwan stratigraphical section in the salawusu river valley keeps a record of 38 sedimentary cycles of alternate evolution of the aeolian dune layers with the fluvio - lacustrine facies and palaeosols since 150 ka bp 位于鄂尔多斯高原毛乌素沙漠东南边缘的萨拉乌苏河流域的米浪沟湾剖面，记录了150kabp以来的38个风成的砂丘砂与河湖相和古土壤交替演化的沉积旋回。
	4.	Accordingly , the dune deposits of the section since 150 ka bp can be divided into 38 alternate evolvement processes of desert and inter - desert periods , which accord with the sedimentary cycles of the section . it is further suggested from now climate in the area that the 38 inter - succession processes of dune deposits and fluvio - lacustrine or palaeosols in past 150 ka actually result from the alternate evolvement of the ancient east asia winter and summer monsoons in the mu us desert during the long geologic times 从这一认识出发，将米浪沟湾剖面150ka以来的砂丘堆积划分为38个旋回的沙漠期与间沙漠期交替演化过程，并认为，该剖面自那时以来发生的38个砂丘沉积与河湖相或古土壤的演替过程，实际上是这一长期地质时代毛乌素沙漠受东亚冬夏古代季风影响交替演化所致。
