  1. 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。
  2. The sahara is known to have had a humid climate during the last glacial stage of the pleistocene epoch.

    據了解，撒哈拉沙漠在更新世最後一個冰川期間氣候是濕潤的。
  3. Ice age refers to the latest glacial epoch

    川北若爾蓋高原紅原泥炭剖面孢粉記錄的晚冰期以來古氣候古環境的演變
  5. Firstly, evidence from depositional pattern suggests that the hsl has experienced an expansion - contraction circle since the late glacial epoch. the expansion and movement of the hsl or desert in early stage were clearly marked by the presence of paleo - aeoline sands. the occurrence of paleosoal characterized the stabilization and contraction of the hsl and also indicated the activity of pedogenesis on the paleo - aeilian sands

    通過系列氣候代用指標的分析，首次發現該地區粒度、磁化率指標值在兩個大的峰值之間有多個小的峰谷出現，表明了在大的氣候變化階段次一級的暖濕?乾冷氣候波動，值的進一步做年齡的小尺度高解析度研究。
