近十年我国海平面变化研究进展

系统地回顾了2006—2015年我国在海平面变化规律、机制及影响领域的最新研究进展。分析了全球及区域海平面以及比容海平面在不同时间尺度上的变化规律;探讨了海平面的变化机制,海表热通量、淡水通量、环流、风应力以及Rossby波对不同区域海平面变化的动力及热力影响;采用统计方法和数值模拟等手段,对21世纪海平面变化进行了预测;同时海平面变化会影响海洋的动力过程(如潮波系统的变化),并进而对近海和海岸带环境产生重要影响(如海岸侵蚀、海水入侵和土地盐渍化、河口咸潮入侵、近岸低地淹没、红树林衰退等)。

Advances in research on sea level variations in China from 2006 to 2015

Recent progresses in research on the regularity and mechanism of sea level variations and their impacts on the offshore and coastal environment in China from 2006 to 2015 are reviewed systematically. The regularities of global and regional sea level variations and steric sea level variations on different time scales were studied, and the mechanisms of sea level variations are discussed, including the dynamic and thermodynamic effects on sea level variations in different seas due to the sea surface heat flux, freshwater flux, circulation, wind stress, and Rossby waves. The sea level variations over the 21st century were also modeled using statistical methods and numerical simulation methods. It is concluded that sea level variations have influenced ocean dynamic processes such as tidal wave changes, and further influenced the offshore and coastal environment through coastal erosion, seawater intrusion, soil salinization, estuarine saltwater intrusion, submergence of coastal lowlands, and decline of mangroves.
