  1. This paper, based on the grain - size analysis and the comparative result of the mz - o scatter gram of ancient aeolian sands in milanggouwan section with the modern dunes in mu us desert, holds that fossil eolian dunes are a proxy of the dune activation, and be regarded as " desert process ", while the overlying fluvio - lacustrine and palaeosols on the dunes are regarded as inter - desert process

    文中根據粒度分析及古今砂丘的mz ?散點圖比較結果，認為古代風成砂丘特別是古流動砂丘是砂丘活化的體現，視為「沙漠期」 ，而砂丘上覆的河湖相沉積與古土壤發育則可視為「間沙漠期」 。
  2. 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

    位於鄂爾多斯高原毛烏素沙漠東南邊緣的薩拉烏蘇河流域的米浪溝灣剖面，記錄了150kabp以來的38個風成的砂丘砂與河湖相和古土壤交替演化的沉積旋迴。
  3. The erosive and sedimentary behaviour of the shifting sand mimics an ever - changing terrain of windswept hills and of avalanches tumbling down steep slopes

    流沙的侵蝕及沉積作用生動地模擬了由迎風山丘及山崩所不斷塑造的地貌。
  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

    從這一認識出發，將米浪溝灣剖面150ka以來的砂丘堆積劃分為38個旋迴的沙漠期與間沙漠期交替演化過程，並認為，該剖面自那時以來發生的38個砂丘沉積與河湖相或古土壤的演替過程，實際上是這一長期地質時代毛烏素沙漠受東亞冬夏古代季風影響交替演化所致。
