摘要

本研究宗旨爲比較分析大地及海洋動力法處理基隆（本島）－小琉球（離島）高程系統連結之精度。全文主要的內容：收集各離島和台灣本島之潮位站資料，研擬連測作業方法，並以小琉球爲例初步測試，評估大地測量及海洋動力法各別應用於高程基準連測理論之精確度。當大地測量法考慮到高屏地區地層下陷因素時，計算結果顯示由東港連測點推算基隆－小琉球之海面地形差爲10.58±5.83cm，與由海洋動力法（DUPOM和POM模式）計算之基隆－小琉球之海面地形差（11.81±5.66cm和11.53±0.78cm）結果相近。

The paper aims to study on vertical datum connected of methods and accuracy between Taiwan and isolated islands. This work includes collecting some tide guage data on isolated islands and Taiwan, and determining method for vertical datum connected. Giving Siao-Liouciou for an example, we can comparing and analyze vertical datum connected of theorem and accuracy with Geodetic and Hydrodynamic methods. Considered descend moment of Kaohsiung-Pingtung Coast, Geodetic method result shows that from Dou-Gun connected point to calculate Keelung (Taiwan)-Siao Liouciou (isolated island) sea surface topography (SST) differences are 10.58±5.83cm. The values are similar to Hydrodynamic methods result that SST differences are estimated to be 11.81±5.66 cm for DUPOM model and 11.53±0.78cm for POM model, respectively.
