摘要
利用广东省沿海珠江三角洲河口区、粤东和粤西17个验潮站潮(水)位资料,通过经典谱分析、最大熵谱法(MEM)和小波分析分析等方法,对广东省沿海的月均海平面变化进行了研究。结果表明,广东沿海月均海平面呈现显著的季节变化和年际变化规律,海平面呈上升趋势,上升速率为1.2～2.0mm/a。
Utilizing the data in 17 tide gauge stations which lie in the estuary of the Pearl River Delta in Guangdong Province,the eastern and western coastal Guangdong Province,we have studied the monthly average relative sea level（RSL） in Guangdong Province via spectral analysis,MEM（maximum entropy Method） and wavelet analysis.The results show that the relative monthly sea level along the coast of Guangdong behaved significant seasonal annual and yearly variation,and the trend of relative sea level was upward and the rate of increasing was 1.2 ～ 2.0 mm/a.
