浦东是一片年轻的土地,除下沙沙带以西沿黄浦江一带早在1700年前成陆以外,其绝大部分成陆时间,不超过1300年-1400年,而且至今仍在向东南方向生长。要谈浦东成陆史,我们首先要讲一个概念——冈身。距今7000年-4000年前,在江海交汇处,海浪把近海泥沙和介壳类动物的残骸(贝蚬螺壳)冲上海滩,逐渐堆积形成明显高出附近地面的自然泥沙堤。这种形如山岗的冈阜,站立在海滨,形成了一条阻挡海水的自然
Pudong is a young land except for the area along the Huangpu River to the west of the sand belt where it was originally formed 1700 years ago. Most of the land was built into the land for less than 1,300 to 1,400 years and is still growing to the southeast. To talk about Pudong into Lu history, we must first talk about a concept - Gang body. 7000 years ago - 4000 years ago, at the confluence of the Jianghai Sea and the sea waves washed the remains of the coastal sediments and crustacean shells (shellfish shells) onto the beach and gradually accumulated to form natural sediment dikes that were significantly higher than the nearby ground. This shaped hillock Gang Fu, standing on the beach, forming a natural barrier to sea water
