    Abstract: 位於中央山脈與海岸山脈之間的台灣東部縱谷位於是歐亞大陸板塊與菲律賓海板塊之縫合帶,其南段為二者初始聚合之處地下構造甚為複雜。由於台東縱谷內之構造大致呈現南北走向,然而至南段卑南山地區,構造發育分散並轉為向東南出海,東部縱谷南端構造及卑南山地區的構造地形演化至今仍是值得探討的議題。 本研究使用衛星大地測量及野外量測卑南山礫岩和台東市區鯉魚山的層態,探討台東縱谷南端的構造活動。永久散射體差分干涉法 (Persistent Scatterer Interferometric Synthetic Aperture Rader, PSI)為較新的衛星大地測量法,傳統DInSAR技術受限由於山區植被,容易導致測量誤差,造成地表監測的不準確性,而永久散射體差分干涉可以解決空間性、時間性誤差。本研究測量地區雖有稻田、茂密樹木,但測量結果證明永久散射體差分干涉仍可獲得地表變形資訊。 利用永久散射體差分干涉法監測所得的地表變形資訊配合野外實際量測的層態與構造結果進一步做比對,可將東部縱谷南端卑南山南冀延伸至卑南溪口及卑南山一帶的活動構造,做完整的探討與推論。 Located between The Central Range and Coastal Range, the Longitudinal Valley is the convergent boundary of Eurasian Plate and The Philippine Sea Plate. The southerly side is where the convergence happened at the beginning stage. The active tectonic underground is beyond complication. The Longitudinal Valley is linear, narrow, and vertical structured. However, the southern tip of Longitudinal Valley is scattered structured and turned to the south-east dripping to the Pacific Ocean. More investigations are needed to study this intricate tectonic issue related to the structure of Pinanshan and the southern tip of the Longitudinal Valley. The work based on satellite imagery measured and field study of the fault formation of Pinanshan and LiYuShan located in Taitung city. Persistent Scatterer Interferometric Synthetic Aperture Rader (PSI) is a new meothod of satellite imagery measurement. The traditional method of measurement, DInSAR is comparatively easily to lead to inaccuracy because of the limitation of the technology. PSI, in the other hand, provides a way to get away for, the inaccuracy of space and time. Though there are some distracters, such as forests and rice paddy, founded in the region which has been measured. The result still proves that the PSI a effective method to gain the transformation information on the surface to the earth. With the use of Persistent Scatterer Interferometric Synthetic Aperture Rader (PSI) and the data acquired in the field research, the author compared the tectonic transformation monitored by PSI to the result of the data gained from the field research. The author provides a thorough discussion and inference of the exact nature of the fault tectonics in the southern tip of Longitudinal Valley extended to the Pinanshan as well as the Pinan region.
