摘要
利用平均海面资料,分析历史资料中吴淞、大沽等旧基准面关系,确定旧基准面建立时的高程与现在国家统一高程系统的关系,阐明地面沉降对基准面关系变化的形响.
In the present paper, the author applies the data information on the mean sea level to analyze the relationship between the conventional datum recorded in the historical data for the areas such as Wusong (in ShanHai) and Dagu (in Tian-Jin Harbour) and to establish the relationship between the elevation system which came up with the convetional datum setting up and the current state-unitified or u-nifomed elevation system. Also the paper describes the impact of the land settlement upon the changes in the relationship between the datum
