大禹治淮的传说在人民中间流传很广,但是作为我国古代著名的“四渎”(江、淮、河、济)之一的淮河,它的发育和成长却很少为人们所了解。当你仔细地翻阅有关研究资料时,就会惊呀发现,我国淮河确是很古老的河流。自上新世至更新世初,淮河平原和华北地块的其它部分一样,在地壳运动中,周围山地凸起,平原相对沉降。沉降的平原并不是简单的一致,而是受构造控制,形成大小不等、深浅不一的凸起和凹陷。如河南的正阳——淮滨凸起,周口凹陷,夏邑凹陷,安徽的砀山凹陷,阜阳凹陷等等。这就为第四纪早期,淮北平原的湖盆、沼泽、低丘、缓岗地貌景观提供
The legend of Dayu governing Huai River spreads widely among the people, but as one of the ancient famous “Four Dwarfs” (Jiang, Huai, He and Ji) in ancient China, the development and growth of the Huaihe River is rarely understood. When you read through the relevant research materials, you will be amazed to find that the Huaihe River in our country is indeed a very old river. From the Pliocene to the beginning of the Pleistocene, the Huaihe Plain, like other parts of the North China block, raised in the surrounding mountains and settled relatively in the plains in the crustal movement. The settlement of the plain is not simply consistent, but by the structure control, the formation of different sizes, different shades and depressions. Such as Henan Zhengyang - Huaibin, Zhoukou depression, Xiayi depression, Anhui Dangshan depression, Fuyang depression and so on. This is for the early Quaternary, Huaibei plain lakes, swamps, hilly, gentle Kong landscape
