Historical Evolution of the Fluvial and Aeolian Landscapes in the Hobq Desert
摘要
Abstract
The Hobq Desert is located in the north of the Ordos Plateau,it is adjacent to the south bank of the Yellow River with zonal distribution from the west to the east,and ten main tributaries flow through the Hobq Desert from the south to the north and converge into the Yellow River,thus a fluvial-aeolian interactional pattern forms.In this papers,the previous research results,historical documents,remote sensing images and other materials were referred to discuss the history of environmental changes and formation causes of the fluvial and aeolian landscapes in the Hobq Desert.The authors hold that there were two stages of development of the Hobq Desert,i.e.the ancient Hobq Desert and the modern Hobq Desert,and the modern Hobq Desert was developed in Holocene;the temperature became high and made the ancient Hobq Desert fixed and died during the last deglaciation.The ancient Hobq Desert was mainly attributed to the geological processes and climatic fluctuations,while the modern Hobq Desert is affected by both natural and artificial factors.The ten tributaries were formed in the early and middle periods of Pleistocene and fully formed in the late-Pleistocene,they started to grow with the neotectonics and affected by regional climatic factors,and then dissected the north of the Ordos Plateau.Moreover,the study showed that the fluvial-aeolian interactional pattern dominated by fluvial process is the main cause resulting in the modern Hobq Desert.关键词
