The SSTA of February and August in 1998 had two peaks, while the wind speed reached its maximum minus anomalies in January and August. In order to find the circulation anomaly in the South China Sea, the circulation of 19952000 had been calculated by the ECOM hydrodynamic numerical model. The elevation and circulation of January and August in 1998 indicated that there were great anomaly of elevation and circulation after this El Nio event.(1)In January, the whole South China Sea had positive sea level anomaly and anticyclonic velocity anomaly, so the cyclonic circulation was weaker than normal.(2) In August, the South China Sea had positive sea level anomaly, especially stronger in the east of Vietnam, and cyclonic velocity anomaly in south, anticyclonic velocity in north, especially strong in the east of Vietnam. So the cyclonic gyre in the north and the anticyclonic gyre in the south were both weaker than normal, and an anticyclonic gyre appeared in the east of Vietnam.

为研究南海环流在1997/1998年的异常变化，利用ECOM水动力模型计算了1995—2000年的南海环流场，分析了1998年1月和8月南海水位和环流的异常分布，二者均存在显著的异常：①1月，整个南海海盆为正的水位异常，流场为反气旋异常环流，冬季控制整个南海海盆的气旋式环流减弱；②8月，南海海盆水位为正异常，特别是越南东部海区出现较强的正水位异常，南海南部的高水位中心扩大北移；异常流场表现为南部为气旋式异常环流，北部为反气旋的异常环流，且在越南东部海区形成非常强的反气旋异常环流中心，使得控制南海南部的反气旋环流和北部的气旋环流均减弱。

First, UWPBL model(The University of Washington Planetary Boundary Layer Model) is used to retrieve typhoon's sea level pressure from sea surface winds data of SeaWinds which aboard on QuikSCAT and these strength results are analyzed. Then the variational method is applied to decompose the sea surface winds field into two parts: the vortex and irrotational environmental flow field, the UWPBL model is used again to retrieve ShanShan and YaGi typhoons' sea level pressure from the vortex flow field, the results of typhoon's central positions are analyzed by comparing the results with the results of direct retrieving, NCEP's data and typhoon annual reports. It turns out that the accuracy of the typhoon's sea level pressure central position has been obviously improved, This method offers a new idea for the study of typhoon from microwave scatterometer data.

本文首先利用QuikSCAT散射计获取的海面风场资料，利用华盛顿大学行星边界层模式对台风海平面气压场进行反演，并对其强度进行了分析；然后对获取的海面风场，采用变分方法对风场进行分解，分解出无旋和有旋风场，对分解出的有旋风场，再利用UWPBL模式对珊珊和魔羯台风的海平面气压场进行了反演，对所得结果与通常直接反演、NCEP海平面气压场及台风报文资料进行一一对比，结果表明：新的反演定位的方法对台风海平面气压场中心气压的定位精度有了大幅度的提高，此种定位的方法为散射计资料在台风中的实际应用开辟了一条新的思路。

This paper analyses the regional relative changes in sea level and causes along the east China coast over the last decades, and concludes that there are different features for south and north of the Changjiang Estuary, the relative sea level rises along the south coastline, while alternate rise and fall occurs along the north, which is associated with tectonism and eustatic sea level change.

本文对近期中国东部区域性海平面相对变化和原因进行了分析与探讨，得出了以长江口为界的中国南北沿岸海平面的差异特征。长江口以南的相对海平面主要表现为上升趋势，而以北则呈交替升降变化。这主要与全球性海平面变化和中国东部沿岸现代构造运动有关。

When sea level drops, forced by Kelioli, river mouth extends eastward and migrates southward, cutting down deeply. On the contrary, when sea level rises rapidly, river mouth jumps northward dramatically and moves westward, goes backward step by step. While sea level changes and river discharge is harmnize, as the geological depositional center is moving eastward and southward, driving by Keliolli and longshore drift, river mouth moves southward slowly, keeps relative stability, and forms the delta towards south slightly.

海面下降过程中，河流河口在科氏力作用下，南移东伸，下切迅速；反之，海面快速上升的过程中，河口则迅速北跳西移，逐步退缩；两者力量对比相当时，在沉降盆地沉降中心东移，并向南掀斜的背景下，在科氏力与沿岸流作用下，发育微微南偏的三角洲，河口缓慢南移，相对稳定。

Between 2,500 yr BP and 1,800 yr BP. This was a neo-glacial age with a cold snap. The ice-cap on the King George Island and Ardley Island advanced. Iso -static adjustment lowered the palaeo -first terrace at the edge of Ardley Island under the high tide sea level. This made the rookeries around Y2 lake disappear and Y2 lake changed into a lagoon. The fact of Y2 lake under the sea level was coincident with the radiocarbon age (2180±95 yr BP) of the modern third raised beach terrace with 14m-height above the sea level near Yin ' Ou lake in the Fildes Peninsula.

对利用沉积记录来研究海平面变化的重视程度很高，但对海平面变化对沉积盆地的影响注意甚少。建议关注海平面升降变化对盆地充填物的作用，对沉积型矿床的控制和对大陆边缘地壳变形的反弹作用过程的研究及定量模拟是一个重要方向，它可能为大陆边缘动力学研究提供一方面的思路。

With sea level rise,the partial tide amplitude will be increased,but diminish in some part area;meanwhle tide counting position of partial tide moves unceasingly to southeast direction;Tide amplitude change causing by sea level rising can be taken the Lvsi port as the boundary,to the north,partial tide amplitude enhances unceasingly,and to south it diminishes,especially in destroyed Yellow river it has less enhancement;The region where has the largest increasing partial teide amplitude also the palce which has the quickest erosion rate.sea level rising has a good relation with the beach erosion.

2海平面上升后分潮的振幅将随之而变大，但在部分区域，分潮振幅随着海平面上升而减小；无潮点相对于现有的无潮点位置均向东南方向偏移；海平面上升导致的潮差变化，大致以吕四为界，以北随着海平面上升，分潮的振幅不断增大，以南振幅减小，其中在废黄河口附近的增幅也相对较小；潮差增大幅度最大的地区刚好是岸滩侵蚀最快的地区，海平面上升与岸滩侵蚀存在很好的对应关系。
