| 摘 要： | 黄河源区是青藏高原荒漠化严重的地区之一,为了遏制黄河源区荒漠化的进一步发展,从地质学的角度分析了荒漠化产生的驱动力机制。结果认为该区荒漠化有异于其他地区,是现代地质作用增强导致了下垫面的改变,气候变化引起多层面的荒漠化,人为及鼠类的活动起着推波助澜的作用;其过程首先是以缓慢的自然荒漠化过程为基础,自然与人为因素共同作用所形成的。

| Abstract: | The desertifieation in source region of the Yellow river is one of the worst in Qinghai - Tibet plateau. from geologi In order to curb the trend worse. The author analyses the driving forces for desertification cal aspects, and produce where is different from other places, natural factors such as the revive of the recently geological activity determining environment changes of the earth surface. The climatic changing led to multilayer and synthesis＇ s desertification, the human activity and the rodent＇ s damage accelerated the process of desertification in source region of the Yellow river. The procedure is first based on the natural desertification, then natural and humans factors combine to act. |
