摘　　要：在第四纪沉积理论基础上,对第三纪沉积速率提出计算方法,并选择牛顿法解渤海湾盆地沉积速率,研究了中国大陆东部边缘渤海湾盆地的沉积过程,得出盆地区域内沉积速率的变化存在3个高峰值,其年龄分别为:距今0～2 Ma、24.0～32.6 Ma、38.0～42.0 Ma,为认识古代环境与地质演变提供了科学的依据.论述了黄河的造陆过程,指出第四纪以来黄河对渤海湾盆地沉积贡献最大.约距今10万年,原海岸线大约以燕山、太行山、嵩山、大别山、黄山等为界,距今10万～1万年间,我国的东部海岸线向外推移1 000余km.华北平原是以黄河为主和其他河流一起挟带泥沙沉积形成的,就是现在陆地海拔在0～200 m高程之间的、占国土面积约12%的中国东部平原.Based on the Quaternary aggradation theory, the paper puts forward a calculation method for the Tertiary aggradation speed, solves the aggradation rate of the Bohai Sea bay basin by Newton!Method, studies the deposition process of the Bohai Sea bay basin, fringe of the eastern mainland, obtains 3 peak age values of 0~2 Ma, 24.0~32.6 Ma and 38.0~42.0 Ma ago respectively of aggradation speed variations of the basin and provides scientific basis for understanding ancient environment and geological evolution. It dissertates the continent-making process of the Yellow River and points out that the Yellow River has made the greatest contribution to the aggradation of the Bohai Sea bay basin since the Quaternary. About 100,000 years ago, the original coastline takes the mountains of Yanshan, Taihang, Songshan, Dabie and Huangshan as the boundary and about 100,000 ~ 10,000 years ago, the eastern China coastline has evolved more than 1,000 km towards the sea. The north China plain is formed by sediment carried by rivers mainly the Yellow River, i.e. the eastern China plain which occupies about 12% of the territory area and situates between 0~200 m above sea level.
