摘　　要：泥河湾盆地是早期人类扩散至东北亚最早证据所在地,越来越多的早更新世遗址的发现使得该地区在研究中国北方早更新世人类演化与生存行为领域备受学术界关注。麻地沟遗址群(MDG)是近年来新发现的早更新世遗址群,它位于泥河湾盆地岑家湾台地古人类活动集中区域,由包括E6和E7在内的9个地点组成。MDG-E6与MDG-E7地点发现于2007年,2012-2013年正式发掘,揭露面积分别为30m2和20m2,出土遗物分别有184件和174件。石制品原料主要取自遗址周边的燧石、白云岩和火山岩,类型包括石核、石片和石器等,剥片和修理技术为硬锤直接打击法且简单随意,组合特征与非洲奥杜威工业(Oldowan)相似。动物化石均很破碎,难以鉴定动物种属。根据地层和初步古地磁测年资料,推测古人类在遗址活动的年龄大致为1.07 Ma BP。The Nihewan Basin, covering the northwest of Hebei Province and northeast of Shanxi Province, is located in the transition zone between the North China Plain and the Inner Mongolian Plateau with an area of roughly 150-200 km2. Bearing the earliest and centralized evidence on the human dispersal to Northeast Asia from Africa, the basin is considered as the key region on the study of the relationship between early hominin evolution and adaptive behavior in North China. This paper will give a preliminary report on a newly discovered Early Pleistocene Paleolithic site complex named Madigou （MDG）, but with particular emphasis on the two sites （MDG-E6 and MDG-E7） of the MDG site complex.Madigou site complex is situated in the concentrated area of Early Paleolithic sites on the Cenjiawan Platform of the eastern part of the Nihewan basin. MDG-E6 and MDG-E7 sites were discovered in 2007 and were excavated in 2012 and 2013 field seasons by the staff from Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences （IVPP）. Archaeological occurrences were buried in the fluvio-lacustrine deposits of Nihewan beds of fine sands, silt and clay, with grey, yellow, brown, and green in color. Geomorphological and stratigraphic comparisons as well as preliminary magnetostratigraphic dating results indicate that early hominins occupied the site before ca. 1.07 Ma. The excavation of MDG-E6 exposed an area of 30m2. In total, it unearthed 127 lithic artifacts, 9 animal fossils and 48 pebbles and cobbles. Archaeological materials were mainly from the altitude of 933-932m, and the feature of archaeological layers is the typical lacustrine sediment of fine sand and silt. Lithic assemblage can be classified into debitage（n=82; 64.57%）, cores （n=44; 34.64%） and retouched pieces（n=1; 0.79%）. Lithic raw materials derive from local sources, including chert（n=48; 37.80%）, dolomite（n=35; 27.56%）, breccia（n=12; 9.45%）, and some volcanic rocks （andesite, basalt, and tuff）. The stage
