根据1957~2006年全球温度和珠江口验潮站平均潮位资料,分析全球气候变暖与珠江口平均海平面上升的关系,并对2030年珠江口海平面上升幅度作出预测。结果表明,近50年来珠江口海平面的上升趋势与全球气候变暖存在显著的正相关关系,预测2030年(前后)珠江口平均海平面比1980~1999年高13~17cm。
Based on the records of Tide gauges, the impact of climate warming on sea -level rise trends were determined by linear regression. The conclusions of this study are : ( 1 ) there exist significant correlations between climate warming and sea - level rise at Pearl River Estuary during 1957 -2006. (2) 13 - 17cm sea - level rise at Pearl River Estuary is projected by a semi - empirical approach around the year of 2030 against 1980 - 1999.
