Abstract: In historical period, the Huang He River flowed through North Jiangsu into the Huanghai sea for nearly 700 years. The abundant load that it carried formed a large delta, a coastal plain and offshore banks. It is due to the shifting of the river estuary that the coastal zone in Jiangsu underwent two great changes in hydrodynamical and sedimentological condi-tions, but the results they brought about are contrary to each other!Through careful analysis of historical literatures and field investigations, this paper at-tempts to discuss the land-forming process of the Huang He Delta, the coastal plain of North Jiangsu and analyse the great effect of the shifting of the river estuary brought on the coas-tal development.
