作为沙漠的主体沉积，易于获取的风成沙-古土壤序列已被广泛应用于全新世风沙活动历史的重建，而对于沙漠中沉积相对连续且分辨率较高湖沼相沉积，特别是沼泽泥炭的研究则相对薄弱，有关二者所代表的风沙活动与湖沼演变之间关系研究更是鲜有涉及。本项目拟以毛乌素沙漠全新世风成沉积和湖沼相沉积地层为主要研究对象，基于年代框架的构建，以风沙活动和湖沼演变之间潜在的关系为切入点，通过代用指标的分析，探讨二者在空间分布和物质输移等多方面的关联，反演特征时期风沙活动和湖沼演变的基本过程，解释不同类型的沉积物所代表的气候意义。研究有助于进一步揭示河湖发育终止-沙漠形成的一般规律，且之于区域土地沙漠化防治和自然资源的合理开发利用亦有一定的科学指导和实践意义。

As primary body in desert, the aeolian-palaeosol sequences are widely used for the reconstruction of Holocene aeolian activities. However, the study on the high-resolution lacustrine sediment is scarce, particluarly for the peat in desert area. Scholars seldom focused on the relationship between aeolian activity and evolution of lake and swamp. In this study, based on the synthetical framework of dating ages, the aeolian and lacustrine (mainly including peat) deposits were selected. We emphasized on the internal relation between them. According to the results of proxies, the relationship concerning the space distribution and material transport were explored. We aim to reconstruct the basic processes about the aeolian activities and the evolution of lake and swamp and explain the climate significance of different kinds of sediments, especially in typical periods, such as Holocene Optimum period or Mediaeval Warm Period. This work will shed new light on the general process of formation of desert. Furthermore, the expected results could have important theories guiding practice and certain practical value to desertification control and resource exploitation and utilization in the Mu Us Desert region.
