我国沿海筑塘防潮,由来已久。古华亭县位在东海之滨,海塘工程亦甚发达,历代修筑频繁,工程规模宏大。至今,海塘仍是上海滨海一带极为重要的防汛设施。上海地区地处长江三角洲东南翼。自古以来随着海岸线向外延伸,沿海地带相继开发,而海塘之筑亦随之由内及外。所以,今天我们到上海海滨,仍不难看到在前沿海塘之后有着层层塘堤平行并列的现象。不言而喻,这每道塘堤,都是标志着一个历史时期的海岸线所在。因此,研究上海历代海塘,
China’s coastal building pond moisture, a long time. Gu Huating County is located in the East China Sea coast, seawall project is also very developed, frequent construction of successive generations, the project is large-scale. So far, seawall is still an extremely important flood control facilities in the coastal area of Shanghai. Shanghai is located in the southeast wing of the Yangtze River Delta. Since ancient times, as the coastline extends outward, the coastal areas have been developed one after another, and the structure of the seawall has also been followed. Therefore, today we went to the seafront in Shanghai, and it is still not hard to see that there are layers of ponds parallel to each other after the frontal seawall. It goes without saying that each pond embankment marks the milestone of a historical period. Therefore, the study of Shanghai seawalls,
