【摘要】 水利史的研究已经证实,历史上黄河北流的河道以禹贡河为北界,以现行河道为南界,在这一区域内摆动迁徙。黄河北流从未进入河北平原的中-西部的白洋淀流域区。造成河道这种演化特点的主要原因是河北平原基底活动构造等因素的影响。除此之外,另一个尚未探索的原因是远古时代河北平原曾发生过一次规模宏大的陨石雨撞击灾害。撞击的结果壅塞了当时黄河下游河道,形成了白洋淀流域区,最终促成了北流河道演化的基本格局。文章最后推测这一史前的天文地质灾害可能是“女娲补天,大禹治水”等神话的事实基础。更多还原

【Abstract】 The study on the hydraulic history have suggested that the northward removal channels of the Huanghe River migrated back and forth, with the ancient Yugong River as north boundary and current channel as the south boundary. The northward removal channel of the Huanghe River had never entered into Baiyangdian drainage area in the middle-west part of Hebei Plain. This kind of channel evolution is affected mainly by the basement tectonic activity in Hebei Plain. In addition, another reason that is not yet discovered might be a large-scale meteorite shower impact disaster occurred in Hebei Plain in the ancient time.As the result of impact, the lower reach channel of the Huanghe River was silted up at that time and Baiyangdian drainage area were formed. Finally, the basic pattern of the northward removal channels of the Huanghe River was taken shape. It is the inferred in the paper that this astrogeological disaster might be the basic fact of some ancient legends and myths, as "Nuwa mended the sky" and "Dayu controlled water" etc.更多还原
