摘要: 中国季风边缘区全新世沙地演化和气候变化自东向西具有明显差异性。东部科尔沁沙地、中部毛乌素沙地呈现典型三段式沙地演化过程,西部共和盆地呈现多阶段多反复的沙地演化特征。东部科尔沁沙地、中部毛乌素沙地气候变化也呈现三段式,西部共和盆地由于地域特征气候变化相对复杂。全新世气候突变事件对各区产生差异影响。太阳辐射强度控制的亚洲季风环流和有效湿度变化影响沙地演化过程。

Abstract: Study of the evolution and climatic variation in the monsoonal margin area in China during the Holocene epoch shows there are obviously differences from the east to the west. Firstly, a typical three-stage evolution process is presented in the eastern Horqin Sandy Land and central Mu Us Sandy Land, while the western Gonghe Basin is characterized by multi-stage evolution. Secondly, in the eastern Horqin Sandy Land and central Mu Us Sandy Land the climate change is also presented in three phases, while the change of the western Gonghe Basin is relatively complicated due to the regional features. Thirdly, the Holocene abrupt climate events have different effects on different regions. The Asian monsoon circulation controlled by the solar isolation and the change of the effective humidity has great influence on the sandy evolution.

Key words: Holocene Epoch, sandy land evolution, climatic change, abrupt events, driving mechanism
