    Abstract: 位於台灣最南端的恆春半島擁有最年輕的地形景觀。由於台灣的造山作用是由北向南傳遞,恆春半島保存了一套最年輕也最完整的岩層露頭。在如此年輕的地形,我們可觀察到非常活躍的構造活動,並藉由這些的構造地形特徵,分析此區域的構造活動歷史。
    ;Hengchun Peninsula is the youngest landscape in Taiwan. Due to southward propagating emergence of the island, the peninsula also outcrops the youngest formations in the orogen. In such juvenile topography, we are able to observe very dynamic geomorphic processes, likewise expect to locate relict landforms before their adjustment to new topographical settings.
    The Hengchun Peninsula was a target of my doctorate survey. I tried to map the present conditions of the landscape evolution and track the directions, rates of the geomorphic processes. Based on fieldwork, DEMs (Digital Elevation Models) processing and profound synthesis of the previous publications, I expected to derive parameterization of the landforms features, which could direct a sense and enhance comprehension of the landscape evolution. Drainage basins and fluvial processes were the major subjects in my methodology, where through knickpoint behavior I extracted the paleo-equilibrium conditions from present stage of the drainage system. Then, knickpoints regression values give the response time of the landscape to the subsurface input. However during the survey I also recognized that the drainage basins are deformed by other feature that influence the landscape evolution- captures. The capture events not only distort the basins parameters but also give valuable information about relict landscape shrinkage. This phenomenon is apparent in the Hengchun Peninsula, where I was competent to map its range and input as another parameter of the landscape development.
    The second part of my dissertation concerned the geological mapping of the Hengchun Peninsula. After synthesis of previous surveys over the peninsula’s geology and number of my field investigations, I built an updated geological map of the area. Especially in the southwestern part of the peninsula, my observation delivered new tectonic concept of the Pliocene to Holocene formations. This new approach benefited to explain few ‘not-solved’ issues and conclusively I believe it is the most complete geological map of the area till present.
