本計畫針對石門水庫供水與桃園台地土地利用、地表變遷、氣候、大氣、陸表與海陸交界面的交互作用等地球「關鍵區觀測」議題，提出主題為「桃園台地都會與海岸帶關鍵區之時空特徵跨域鏈結研究」之整合案。其中，本子計畫搭配整合案，擬以地球物理探查技術中之地電阻影像剖面法，協助理解近地表之水文地質條件，提供區域地表地下水交換與陸氣交互作用模擬的檢定驗證依據。本子計畫將應用即時、快速之地電阻率監測技術，從兩大面向進行探究，一者係配合子計畫三進行近地表地層含水程度變異之快速監測掃描；另一則配合子計畫一，將地電阻監測作業佈置於桃園地區海岸場址，藉由海、淡水之電阻率差異，掃描海岸帶之海淡水介面變化行為。通過本案預期可梳理桃園台地區域能量與質量傳輸機制，並瞭解過去地表演化、土地利用與氣候變遷相關影響，以進一步模擬未來氣候與人為改變下，對桃園台地與海岸帶地形、地貌可能之衝擊。 ;The integrated project “Cross-Disciplinary Studies on Spatio-Temporal Characteristics of Critical Zone in Taoyuan Tableland and Coastal Area” aims to address key issues about Taoyuan Critical Zone (CZ), such as the water supply of Shimen Reservoir, the land use and surface change in Taoyuan Tableland, climate and atmosphere in Taoyuan area, and land-sea interface at the Taoyuan coastline. We in the Sub-project II (this sub-project) propose to use the geo-electrical resistivity imaging (ERI) method, one of the geophysical exploration technology, for understanding the hydrogeological conditions near the surface, and providing information to regional surface groundwater exchange (Sub-project I) and land-air interaction (Sub-project III) simulations. We will apply real-time and intensive electrical resistivity monitoring data to investigate the CZ subject from two aspects. Cooperating with Sub-project III, the rapid ERI monitoring data can infer the variation of water content in the soils and strata near the surface. Also, cooperating with Sub-project I, the ERI monitoring task will be performed at the coastal site in Taoyuan area so that the dynamics of the sea and fresh water interface change can be observed. The integrated study is expected to figure out the energy and mass transportation mechanism of the Taoyuan Tableland, to understand the land use and climate change, and to evaluate the impact of climate and man-made changes in the future.
