验潮站能够观测海平面长期变化,并被用于重构全球平均海平面上升.然而,中国沿海区域的海平面长期变化尚未被揭示.本文构建了一种数据同化方法,可以重构中国沿海地区1950年以来的海平面上升.该方法以全球验潮站观测为约束,同时利用气候模式输出的动态海平面和陆地水质量迁移导致的海平面指纹效应.本文重构的全球平均海平面上升与之前的研究结果接近.中国沿海地区20个验潮站的重构结果显示,1950~2020年中国沿海平均海平面上升速率为(1.95±0.33)mm a^(-1),高于同时期的全球平均上升速率(1.71±0.17)mm a^(-1).此外,本文还发现,中国沿海平均海平面上升速率在1980年以后是之前速率的3倍以上,速率从1950~1980年的(0.84±0.28)mm a^(-1)增加到1980~2020年的(3.12±0.21)mm a^(-1).该发现说明中国沿海海平面存在显著的加速上升,这些结果增进了对中国沿海海平面长期变化的理解与认识.

In th.s article, th. sediment transport processes in th. Kh.ran Strait between th. mainland Iran and Qesh. Island at North.Central Persian Gulf are studied in regional scale in a compreh.nsive manner. Th. objectives of th.s study include defining th. type and origin of th. sediment, th. influencing factors, and th. dominant mode of sediment transport. Four possible scenarios of sediment processes in terms of sediment sources and influential environmental forces are examined. Th. results of th. conceptual and 2d numerical model of MIKE21 applied for th.s purposes indicate th.t th. sediment sources in th. transport processes are mainly provided by th. sediments suspended from th. central and eastern zones of th. strait bed. Oth.r sources including input from rivers do not h.ve direct influence on th. processes. Th. results are applied to th. study of morph.logical ch.nges for engineering applications including th. pattern and amount of deposit in th. Ra.a.e port approach.ch.nnel and h.rbor basin. Th. pattern and amount of annual sediment deposits in th. approach.ch.nnel predicted by th. model is satisfactory, compatible with.annual dredging records.
