| 摘要: |
| 近2000年来淮河流域的洪涝灾害十分频繁。作者认为淮河中游的洪涝灾害与洪泽湖的演变有非常密切的关系。洪泽湖本是人工筑堤蓄水而形成的。湖区水位的上升与湖底淤高,势必会引起淮河中游发展溯源加积和洪水位的上升。估计鲁台子-蚌埠河段平均每公里河长加积了约3400×104t泥沙,由此造成泄洪不畅,加剧了洪害。 |

| Abstract: |
| 338 times of heavy flood and waterlogging catastrophes happened in the Huaihe River Basin from 185 B. C. to A. D. 1982. These events were relevant to the changes of geographic environment in that region, one of the important factors was the forming of a man-made lake located at the end of the middle course of the Huaihe River. Hongze Lake was formed first in the Han Dynasty in about A. D. 200 in order to prevent the plain of the central part of Jiangsu Province from the encroachments by Huaihe River flood. And since then, the water level in the lake and the height of the lake bottom have risen constantly, which have led to the development of the headward accumulation and the meander bend in the lower reaches of the middle course of the Huaihe River. Hence, many flooding catastrophes took place along the middle course of the Huaihe River during the last 2000 years. |
