摘要
明清时期,黄河夺淮经由苏北入海,在口外迅速造陆,至1855年北徙时止共造陆10000平方公里以上,河口更是向海推进了90公里。黄河造陆与苏北灾害发生关系密切,主要体现在三个方面:一是提高了河湖决溢的机率,黄河水灾频发;二是导致了沿海潮灾的显著增加;三是对当地土质产生了深远影响,盐碱化严重,地力下降,种植制度也被迫改变。
In the Ming and Qing Dynasties, the Huanghe River engulfed the Huaihe River at North Jiangsu and flowed to the sea, and the land was thus created near the estuary. The land had amounted to be 10, 000 km2 and the estuary pushed towards the sea by 90 km by 1855 when the Huanghe River shifted northward. The Huang-he River＇ s land making had close connection with calamity in North Jiangsu area, which are manifested in three facts： heightening the probability of bursting of the rivers and lakes and resulting in the frequent flood disasters, causing the frequent tidal calamities in inshore areas, and eroding the farm soil seriously-extending saline land and reducing the fertility, and forcing the system of crop to change.
