南四湖位于淮北平原中部,是我国第六大淡水湖泊,素有“日出斗金”之说。如今,南四湖已成为苏、鲁两省防洪、灌溉、水产、航运、改善生态环境等多功能综合利用的大型湖泊。 南四湖的水利工程绝大部分兴建于50年代末期,已形成水利固定资产26亿元。由于工程老化失修,加之人为破坏,致使防洪除涝能力不断降低。 Located in the central part of Huaibei Plain, Nansi Lake is the sixth largest freshwater lake in China. It is known as “sunrise bucket gold”. Today, Nansi Lake has become a large lake with multi-functional comprehensive utilization such as flood control, irrigation, aquatic products, shipping and ecological improvement in the two provinces. Most of the water conservancy projects in Nansi Lake were built in the late 1950s and fixed asset of water conservancy reached 2.6 billion yuan. As a result of project aging disrepair, combined with man-made damage, resulting in flood control and waterlogging capabilities continue to decline.
