| 摘 要： | 根据东晋以来有关吴淞江水系演化和水利工程的记载,通过对近1500年有关史料的整理,发现吴淞江水系日渐淤塞与海平面作用下的太湖流域地貌演变规律密切相关,与长江河口演变密切相关.由此得出:吴淞江水系演变的自然规律是其淤塞的主要原因,未来太湖流域的水环境整治、水利工程等建设必须遵循海平面作用下的地貌演变规律.

| Abstract: | The present study has collected historical records on changes and conservancy projects of the Wu - song -jiang waterway system since Jing Dynasty. We found that increasing siltation during the past 1500 years has been induced by geomorphologic change of the Taihu drainage basin in response to the sea level rise. It is also closely related with the progress of the Changjiang river mouth. We indicate that the siltation of the Wu - song - jiang waterway system is the result of its evolution. We suggest future management of the Taihu drainage basin should obey the law of geomorphologic change in association with the sea level rise. |
