黄河夺淮对苏北水环境的影响

Influences of Discharge of the Yellow River into the Sea Through the Huai River Estuary on Water Environment in Northern Jiangsu Region

自宋、金以来的黄河改道、夺淮夺泗,造成淮河水系发生重大变迁,对苏北地区的水环境也造成了重大影响体现,并主要体现在河流环境和湖泊环境两个方面。就河流环境而言,黄河夺淮使淮河失去了入海出路,打乱了原有水系,淮河入江水道的形成、苏北灌溉总渠的开辟、沂沭泗水系的变迁以及废黄河的形成,都是黄河夺淮在苏北地区留下的印迹。就湖泊环境而言,促成了洪泽湖、南四湖和骆马湖三大湖泊的形成。

Since Song and Jin Dynasty, the incident of the Yellow River discharging into the sea through the Huai River estuary has caused the huge change of the hydrographic net of the Huai River. The influences of the discharge on the water environment of northern Jiangsu region were mainly reflected in the river and the lake environment. For the river environment, the discharge of the Yellow River through the Huai River estuary made the Huai River lose its way into the sea, and the original water system was disrupted. Thus, the watercourse of the Huai River into the Chan^iang River was formed, the General Irrigation Canal of northern Jiangsu region was established, and the Yi-Shu-Si river system was changed. Finally, the ancient channel of the Yellow River was abandoned. For the lake environment, it has contributed to the formation of the Hongze Lake, the Nansi Lake and the Luoma Lake.
