中文摘要：

利用临时验潮站横门站的1 a潮位观测资料、下大陈站长期验潮资料以及4个垂线测站的大、中、小潮潮流同步观测资料,分析了台州湾附近海域的潮汐、潮流特征,并探讨了海平面空间分布特征的影响因素.结果表明：横门站与下大陈站的潮汐类型均属于正规半日潮类型;横门站年平均潮差大于下大陈站4cm;2站平均涨、落潮历时相当;台州湾除T-1站受地形约束潮流运动为往复流外,其他3站潮流基本呈旋转流形态,且为顺时针旋转,椭圆旋转率在-0.35~-0.3范围内;台州湾海域的潮波为驻波性质,涨、落潮最大流速发生在中潮位附近,涨憩、落憩和转流发生在高、低潮位附近.横门站2009年7—9月的平均海平面与下大陈站同步平均海平面的差值较其他月份明显偏大,这主要是受椒江径流的影响.

英文摘要：

With the tidal data at the Hengmen Station and Xiadachen Station,and the tidal currents for spring,moderate and neap tides observed simultaneously at four in situ stations,the characteristics of tide and tidal current in the sea area near the Taizhou Bay were analyzed.The factors influencing the spatial distribution characteristics of sea surface were examined.The results show that the tides at the Hengmen Station and Xiadachen Station are regular semidiurnal.The annual average tidal range at the Hengmen Station is 4 cm greater than that at the Xiadachen Station.The duration of the flood and ebb tides at the two stations are almost equal.The tidal current at T-1 Station is rectilinear because of the terrain constraints,and are clockwise rotated at other three in situ stations in the Taizhou Bay with an elliptic rotation rate ranging from-0.35 to-0.3.The tidal waves in the sea area near the Taizhou Bay are standing waves.The maximum velocities of the flood and ebb tides often occur at the mean tidal level,the slacks of the flood and ebb tides are often occur at the high and low tide levels,respectively.The difference of the mean sea surface between the Hengmen Station and Xiadachen Station from July to September in 2009 is much greater than that in other months of 2009,which results from the influence of runoff in the Jiaojiang River.
