中文摘要	研究了淮河支流颖河上游嵩山东麓-典型全新世黄土-古土壤剖面，获得了较高时间分辨率的磁化率、粒度成分和〉0．063mm粒级百分比含量等环境代用指标系列。通过地层对比研究，确定了该剖面的基本年代框架。分析了颖河上游全新世黄土-土壤磁化率、粒度特征，论证了颖河上游全新世黄土-土壤物质粒度成分与黄河泛滥沉积沙尘暴活动关系，揭示了颖河上游全新世黄河泛滥平原沙尘暴活动特征。3100aBP以来气候趋于干旱，黄河下游泛滥频率增加，风沙活动范围显著扩大，沙尘暴活动强烈。
英文摘要	A Holocene loess-soil profile is studied on the fiver terraces, hills and plateaus of the east piedmont of the Songshan Mountain in the upper reaches of the Yinghe River as a tributary of the Huihe River. Higher resolution proxy data of magnetic susceptibility, particle-size distribution and 〉 0.063 mm% were obtained from the profile. Chronology framework of the data series was decided by a stratigraphic correlation. Based on analysis of characteristic of magnetic susceptibility and grain-size of the loess-soil profile, the paper discussed the relation of the grain-size distribution of loess-soil sequences in the upper reaches of the Yinghe River and the sandstorm activity in the Yellow River floodplain, then probed into the characteristic of the sandstorm activity during the Holocene climatic various stages in the Yellow River floodplain. During the late Holocene （3100 -0 a B. P. ） while the climate was tended to become arid, the flooding frequency in the lower riches of the Yellow River was increasing, the area of dust activity extending, the sandstorm activity intensity was more strong.
