在揭去耕土层后即露出早期文化层。地层的堆积为一个陶片、石器、动物骨骸十分丰富的地层与一个相对纯净的淤沙层相叠压,共有4个这样的淤沙层。这些淤沙层应该是洪水期江水上涨时形成的,如经搬运,是不可能还与其它文化层截然分开的。其次,那些包含丰富的陶片、石器、动物骨骸的地层一般都是从东侧向西侧倾斜,似乎是当时人类倾倒垃圾时的状态。另外许多陶片成堆出现,经拼和即可修复。这些现象均说明这些早期堆积是没有经过搬运的原生堆积。 After exposing the topsoil reveals the early cultural layer. Stratum accumulation of a pottery, stone, animal bones are very rich strata and a relatively pure sediment layer stack, a total of four such silt. These silt layers should be formed during the flood season when the river is rising. If carried, it is impossible to separate them from other cultural layers. Second, those strata of rich pottery, stoneware, and animal bones generally tilt west to east, apparently at the time of the human dumping of rubbish. In addition, many pottery piles appear, by fight and repair. All of these phenomena indicate that these early accumulations were undisturbed and piled up.
