摘要
海平面上升是全球关注的问题.对海平面上升研究的方法、数据来源和研究结论进行了综述,分析了验潮站数据和T/P卫星数据的优缺点及引起海平面变化的原因和海平面变化中的一些周期因素,指出我国近海海平面上升的可能趋势及幅度,对海平面上升率分析和上升量预测中存在的一些问题进行了分析.此外,还对海平面上升后可能对海岸侵蚀、风暴潮灾害、盐水入侵和洪涝灾害的影响及其防御措施进行了分析,以期综合了解对海平面上升的研究现状和进展.
The sea-level rise is a globally concerned problem.From 1980s comprehensive researchers have been focusing on the sea-level changes in the short-scale,and have done a lot of studies and predictions.Summary of the study methods,data sources and main conclusions of sea-level rise is given in this paper,and the advantages and shortcomings of the tide gauge data and T/P satellite data as well as the reasons and periodical factors of the sea-level rise are analyzed.And the trend and amplitude of the sea-level rise and some problems in the research of rise rate and range prediction are also analyzed.In addition,a considerable number of researches on impacts of sea-level rise on coastal erosion,storm surge disasters,saltwater intrusion and flooding disasters and its defense measures are carried out in order to give readers a comprehensive understanding of the present situation and progress in this subject.
