  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. This work carries out a temporal - spatial analysis and comparison in facial pattern, grain - size, and susceptibility of the sediments of the hunshandake sandy land ( hsl ) on the basis of studies of more than fifty geological sections, a number of samples collected from surface sands as well as results derived from previous studies. the preliminary results of this work provide new environmental information of the working area, which makes it possible to have a brief discussion about the evolution of the hsl since the late glacial epoch. this work can be summarized as the followings

    晚冰期，渾善達克沙地全面擴張，達到了沙漠化最大規模，剖面中的古風成砂是最直接的證據，此時氣候乾冷；全新世早中期，渾善達克沙地成壤比較好，是一個大面積成壤期，相當于全新世適宜期，此時氣候暖濕；全新世晚期，渾善達克沙地沙漠化正過程加強，在沙地各剖面上普遍發育風沙沉積，氣溫較乾冷；目前：渾善達克沙地為另一成壤期，成壤作用相對于適宜期較差，氣候乾暖。
  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。
  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。
  5. The degree of sandy desertification will be exacerbating unless some combating measures are put in effect ; through surveying the causes of sandy desertification and its development, we think that the natural basis of sandy desertification is climate changes, landforms, features of sediment and the condition of hydrology, and its immediate cause is the unreasonable activities of human being

    探討了沙漠化成因以及發生發展過程，認為，氣候、地貌、沉積物以及水文條件是壩上地區沙漠化的自然基礎，而人類不合理的經濟活動是沙漠化發生的直接原因。
  6. Rather than being a standing sea slowly accumulating sediment, meridiani seems to have the characteristic chemistry of transient lake beds in a terrestrial desert, or salt flats on a seashore

    梅里蒂亞尼平原的化學表徵使它看上去更像是內陸沙漠中短期存在的湖泊的沉積礦，或海岸上的鹽帶平地，而非長期存在的海洋中緩慢聚集的沉積物。
