中文摘要	库布齐沙漠位于鄂尔多斯高原北部,东西走向呈带状横于黄河南岸,十大孔兑由北向南贯穿沙漠汇入黄河,形成风水交互的水沙格局。结合前人研究成果、古籍、遥感影像等资料,梳理并探讨库布齐沙漠水沙景观的演变历史及形成原因。研究认为库布齐沙漠发育过程可分为两大阶段: 古沙漠阶段和现代沙漠阶段,现代沙漠发育于全新世,末次冰消期气温回暖,使得古沙漠固定并消亡,古沙漠主要源自于地质作用和气候波动,而现代沙漠则是人为和自然的共同作用; 十大孔兑发育在更新世早- 中期,全面形成于更新世晚期,主要受到新构造运动及区域气候因素的影响开始发育并切割鄂尔多斯高原北部。同时研究指出,流水占主导的风水交互模式是现代库布齐沙漠水沙格局的主要成因。
英文摘要	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 In this papers,the previous research results,historical documents,remote sensing images and other materials were referred to discuss the history of environmental changes and formation causes of the fluvial and aeolian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.
