| 摘 要： | 沙漠化是全球气候、地表岩石、区域构造演化所控制的一种地质事件。岩石记录表明，古沙漠环境在中生代中期就开始了，第四纪以来南北两半球各存在一条中纬度沙漠带，中国的沙漠化是全球沙漠化进程的一个组成部分。人类活动是局部的，在整个地球沙漠化进程中只是起到一个加速剂的作用。 |
| 关 键 词： | 地质演化 沙漠化 古沙漠 沙丘岩 |

| Abstract: | Desertification is a geological phenomenon affected by global climate, rocks on the earth's surface, and the development of regional geological structure. Rock records indicate that the ancient desert environment began at middle Mesozoic. There has existed a middle latitude desert zone in the south and north hemispheres respectively since Quaternary. Desertification in China is a part of global desertification process. Human activity is regionally restricted, serving as an accelerator. |
| Keywords: | geological evolution desertification ancient desert dune rock |
