摘要
本文取珠江口28个验潮站1950—1985年观测记录,用最小二乘方回归直线方程进行计算,求出各站的水位升降速率,绘出三角洲各站的升降速率分布图。结果大部分测站均有不同程度的上升趋势,平均速率为2.028mm/a,到2000年水位将比1985年上升3cm多。
We took tide-gauge records of 28 stations from 1950-1985 in the Pearl River Estuary, and calculated the number indicated in a linear regression line, finding the ratio of elevation velocity of each station in the delta. We also made a map of its distribution. The conclusion is that there is an elevation tendency of different degrees at most of the stations. The average elevation ratio is 2.028mm/a which means that in the year 2000 sea level would be over 3 cm higher than in 1985.
