【摘要】 本文根据历史记载、古地图对比、考古和地质资料分析,探讨了台湾岛台南地区在明末清初(公元1622—1724年)的海陆变迁。结果表明,台南平原是上升的滨海平原。明末清初年间,台南市安平之间曾为宽约4km、深3—14m的“台江”海域,后来海岸西移,至清道光末年(1842年)成陆。究其主因乃地壳上升(平均约4mm/a)和泥沙淤积(平均约30mm/a)。该区自明末(1622年)至20世纪初曾出现过3次海面上升现象。更多还原

【Abstract】 Land-Sea Changes in Tainan region are dealt basing on historical, records, Palaeogeographic maps, archaeological and geological studies. Tainan Plain is a raised coastal plain. There was "Taijiang" Sea area between Tainan city and Anping during the late Ming and early Qing Dynasties (1622—1724 A. D.). Its was about 4 km wide, and 3—4 m deep. And later on, the Coast moved westward. "Taijiang" emerged into land in 1842. The main cause was the rise of crust is an average rate of 4 mm/a and sand and mud siltation is an average rate of about 39 mm/a. The sea level rose three times in study area from the late Ming Dynasty (1622 A D.) to earlg 20th century.更多还原
