| 摘 要： | 利用光电子式积雪深度测定仪对毛乌素沙地的新月型流动沙丘风沙流动运移规律进行了长达7年的连续测定及定位研究，结果表明，新月型沙丘迎风坡基本处于风蚀过程，落沙坡处于积沙过程，而沙丘顶部则因大风天气特征的变化具有风蚀和积沙过程，落沙坡和迎风坡的风蚀，积沙变化过程与大风发生的频率，风速有密切关系。

| Abstract: | Continuous determination and orientation research have been done for 7 years on moving rules of sand of storm of moving crescent dune in Maowusu sandy land by use of photoelectron snow retention depthsounder. The result showed: windward slopes of crescent dune are basically in the process of wind erosion. Sand fallen slopes are in the process of accumulated sand. The top of dune is in the process of wind erosion and accumulated sand because of the change of weather characteristics of gale. The change of wind erosion and accumulated sand in sandfallen slope and windward slope has a close relation with frequency and speed of gale. |
