    摘要: 電探法是一種應用非常廣的地球物理探勘方法,其對於地下水的探測、環境變遷、斷層描繪、探礦等等,具有良好的解析能力。野外探勘常用的電探方式有兩種,一為直流電阻法,另一為人控音頻大地電磁波法,其使用時機係依探測所需之目標及測區地形地物而定。 本研究主要利用直流電阻法與人控音頻大地電磁波法研究台灣西南海岸平原全新世以來的環境變遷,共完成591個垂直電探測點,39條二維地電阻影像剖面測線,28條人控音頻大地電磁波法測線,主要研究內容如下: ㄧ、全新世初期(距今10,000?12,000年)西南海岸平原各地海岸線電阻率。 二、全新世至今海岸線電阻率與年代關係。 三、全新世至今西南海岸平原環境變遷(包含河道、海岸變遷、地層含鹽度等等)。 四、西南海岸平原二維電性地層構造。 Geoelectric methods are widely used in the geophysics. It has good resolution in groundwater prospecting, mapping the changes of depositional environment, fault identification, and mineral detection etc.. Two common electricity methods used in the field are the direction current resistivity (DC resistivity) method, and the controlled source audio-magnetic telluric (CSAMT) method. They time for for applying the methods depend on the survey target, man-made features, and geography. The purpose of this research is studying the changes of depositional environment in the southwestern coastal plain of Taiwan by using DC resistivity and CSAMT methods. Total of 591 VES locations, 39 RIP lines and 28 CSAMT lines were carry out in the study area, main aim of the researches are as following: 1. Studying the southwestern coastal resistivity of Taiwan from early Holocene to now. (from 10,000?12,000 years to now) 2. Finding the resistivity between the depositional years and coastal resistivity from Holocene to now. 3. Study the changes of depositional environment changes of southwestern coastal plain from Holocene to now. (from 10,000?12,000 years to now) (include the changes of river course, coast and the salinity of stratum) 4. Delineating the two-dimension electrostraigraphic structure in southwestern coastal plain.
