| 摘 要： | 探讨了地处青藏高原上的共和盆地，自全新世以来，地貌发生一系列的变化特征，详细地分析了盆地干旱特征的成困，指出了除青藏高原自身隆起，导致西风环流影响分布的因素和盆地地形构成的干旱地理环境外，造成共和盆地目前大面积草场沙漠化的原因与人为因素有关。同时，该文也为二十一世纪我国西部开发提供了参考。

| Abstract: | Since Holocene,the extreme uplift of Qinghai-Tibetan Plateau has resulted in the formation of modern monsoon.With the arising of Gonghe Basin,draught and cold climate have been playing an important part in the developmert of landform. The westerlies are divided into two branches and enforce the north branch.Influenced by Gonghe Basin,Qaidam Basin,monsoon and draught,forests and pasture are developing into desert gradually.The downcut of Yellow River makes the land step-like,thus recording the developing procedure of the landform,the economy and culture.Nowadays,the abuse of land and excessive exploitation of forest have resulted in a vicious circle of the grassland environment. |
