| dc.description.abstract | 位於台北盆地西側的山腳斷層，被認為是大台北都會區中最主要之活動斷層，因此對於山腳斷層及其鄰近地區之地表變形監測，是現今非常重要的課題。衛星雷達差分干涉法已被成功的證實為快速有效且全面的地表變形測量工具，但傳統差分干涉技術在較低同調的空間及較長時間的基線上，應用有其測量限制。本研究因此採用永久散射體差分干涉法（PSInSAR）與短基線差分干涉法（SBAS）兩種方法，針對台灣北部地區1993年至2008年的地表變形進行觀測，並將分析結果與GPS及水準資料做比較，探討台北盆地近年來的地表變形情況及可能發生機制。由研究結果得知，在1993年至2001年間，台北盆地的抬昇主要受控於地下水上升後反應之地表回脹；2003年至2008年間，台北盆地再度發生沉陷，其可能受控於許多大型工程及高層大樓興建，大量抽取地下水而導致。此外，近年盆地沉陷最嚴重之區域都集中在山腳斷層南段的五股附近，推論與淺層沖積層壓縮及山腳斷層的活動有關；大油坑上方之地表相對於周圍呈現抬昇之情形，此現象可能與底下液態作用相關。

| dc.description.abstract | I used the PSInSAR and Small baseline techniques to investigate the surface deformation of the northern Taiwan area, including the Taipei basin and its surrounding mountain areas. Integrating the Persistent Scatterer Interferometry (PSInSAR) and Small baseline subset InSAR (SBAS) results, I observed some deformation events in northern Taiwan including: 1) The Taipei basin had experienced uplift from 1993 to 2001, which may relate to aquifer rebound. 2) In contrast the Taipei basin had subsided from 2003 to 2008 possibly due to massive pumping of groundwater. 3) In the western of Taipei basin, the ground subsidence from 1993 to 2008 may be caused by the compaction of shallow sediments and interseismic deformation of the Sanchiao fault. 4) The Da-You-Kan area had been uplifted from 2003 to 2008 that may be caused by magmatic or geothermal activities. Further comparisons between the PSInSAR, Small baseline, and the corresponding leveling data show a coincident pattern, and therefore largely improve the authenticity of radar interferometry.
