摘要: |
骆马湖位于江苏北部,其湖盆是由郯庐大断裂带活动而形成的断裂凹陷。地质时期曾因古水文网的变化而成湖。历史时期因黄河南移夺泗、淮后,黄、沂诸水屡屡漫溢,到明代终于集水潴积于湖盆而成一较大之湖泊。后因黄河泥沙严重淤积及围垦之兴起,到民国时前后三百余年终于淤积面消亡成陆。1958年随治淮工程开展,经筑堤闸,拦蓄沂、运之水又复新生。 |

Abstract: |
Luoma Lake, lying in the north of jiangsu Province, used to be a fault sunken block caused by the movement of the great Tanlu Fault. It was formed into a lake due to the change of ancient water system in geological age. After the Huanghe River changed its course into Sihe and the Huaihe River, Huanghe, Yihc and other rivers flooded frequently, which made the lake expand in Ming Dynasty. In recent 300 years, the lake was gradually silled up along with deposition of the Huanghe River sediments and reclamation.After 1958, with the progress in the project of "Regulating the Huaihe River", Luoma Lake was dammed to be a large man-controlled lake which at present performs comprehensive function of flood control, irrigation, fishery, navigation and etc. |
