Abstract: On the basis of the Shunzhi Relief Map published in 1926, the historic landform in the North China Plain is studied and a large quantity of special geomorphic units-dish-shaped pits are discovered in the Baiyangdian drainage area. In studying the individual appearance and total distribution of these special pits, especially by the digital elevation model (DEM), the authors have realized that the "dish-shaped pits" might be the remains of impact craters on the Quaternary loose deposit and inferred primarily that an impact event of a large-scale meteorite shower might have occurred in this area. After long-time erosion by surface water and artificial transformation gradually, some larger craters finally formed the Baiyangdian Lake.The impact of meteorite shower resulted in a prehistoric huge astrogeological disaster, which produced significant effects on the prehistoric environment and culture development since then.
