黑龙江省中部山区由南部的张广才岭山脉和北部的小兴安岭山脉组成,二者以松花江相隔。中部山区以西为开阔的松嫩平原,向东为平坦的三江平原,往北为相连的大兴安岭,面南为绵延的长白山山脉。以往中部山区报道的旧石器遗址有阿城交界1和嘉荫常兴屯2遗址,但在这些遗址发现的所谓石制品的人工性质还存在争议,该地区的旧石器考古还基本处在空白状态。最近几年新发现的材料在很大程度上改变了这种状况,目前虽然对这些遗址的研究还处在起步 The central mountainous area of ​​Heilongjiang Province consists of the Zhangguangcailing Mountains in the south and the Xiaoxing’an Mountains in the north, separated by the Songhua River. To the west is the Songnen Plain that is open to the west of the central mountainous area, to the plain Sanjiang Plain to the east, to the Greater Daxing’an Mountains to the north and Changbian Mountain to the south of the face. Paleolithic sites reported in Central Mountainous Areas in the past have two sites, Acheng 1 and Jiaxing Changxingtun 2 sites. However, the artificial properties of the so-called stone products found at these sites are still debated. Paleolithic archeology in the area is still basically empty . The newly discovered materials in recent years have largely changed this situation, although at present the research on these sites is still in its infancy
