| 摘 要： | 本文探讨了南疆干旱土石膏的聚集和成土条件之间的关系。结果表明:南疆干旱土区雨量小,对现代石膏聚集的影响不大;石膏含量和形态与母质类型有关,不受质地的影响;石膏层常发生在洪积扇的上部,稳定的高阶地,时间较长,是一种地质形成物。

| Abstract: | Relationship between gypsum accumulation and soil-forming conditions in Aridosols in the South of Xinjiang was explored. The results show that the effect of precipitation upon modern gypsum accumulation is not evident. The content and shape of gypsum is not related to soil texture, but to parent material. The gypsum layer appears commonly in the upper part of alluvial fan and stable high terrace, and has been in the place for long as a result of geological vicissitude. |
