    摘要: 本文分別利用衛星測高法及海洋水準法兩種方法求定東經119°~123°, 北緯21°~26°海域之海面地形. 衛星測高法藉由平均海平面及台灣區域性大地起伏模型求得台灣週遭海面地形, 初步成果台灣週遭海面地形範圍約介於0.4~1.8公尺左右；海洋水準法藉由海水深度0~1000公尺海水之溫度、鹽度及表面壓力資料, 利用動力地形與標準動力地形之差異, 求得台灣週遭海面地形, 初步成果台灣週遭海面地形範圍約介於0~2.8公尺左右, 且兩方法所得之海面地形皆可辨別出黑潮活動範圍. 本研究將藉由內插求得台灣本島及各離島潮位站之海面地形, 進而探討各潮位站間海面地形之差異關係.
    In this study, the sea surface topography is determined by satellite altimetry method and marine leveling. The areas of this research are from longitude 119°E to 123°E and from latitude 21°N to 26°N. Satellite altimetry method obtains the sea surface topography determined by the mean sea surface and geoidal undulation model of Taiwan. The primary result of the annual sea surface topography around Taiwan is about 0.4 to 1.4 meters. The difference between the standard dynamic topography and the standard reference surface, the sea surface topography, is determined by marine leveling which utilizes the sea temperature and salinity data which are from depth 0 meters to 1000 meters. The primary result of the annual sea surface topography around Taiwan is about 0 to 2.8 meters. The two methods can recognize Kuroshio Current. Using the interpolation method to get the sea surface topography of tide gauges in Taiwan and the off-shore islands, and to obtain the difference between each tide gauge.
