摘　　要

　　本研究以台灣西南部雲林至高雄間的海岸為研究區，採用文獻分析、航照判讀、地圖比對、野外實察等方法，探討十七世紀以來本區洲潟海岸的變遷，成果得知十七世紀台灣西南部洲潟海岸共有笨港、蚊港、倒風港、台江、堯港、打鼓港等潟湖，內海海岸線大致與現今等高線5m線相當,總面積約有615km2。受到地瞉隆升、河流輸沙、地形坡降、降水集中、海埔地開發、堤防興建等因子影響，三百多年來潟湖已漸淤填，1990年總面積約僅存60km2，整體海岸線呈向西推移的趨勢。內海陸化後多開發為魚塭、鹽田及旱田，其殘存水域則闢建為港口或養殖牡蠣。深入瞭解古洲潟海岸環境，有助於土地開發規劃利用之參考。



關鍵字：洲潟海岸、台灣西南部。

Abstract

　　The coastal landform in southwestern Taiwan is characteristic of liman coast. The inside coastline of lagoons was near the contour line of 5m in 17th century, the total areas of lagoons is about 615 km2. Due to the land up-lifting, rapid sedimentation, intensive rainning and human cultivated, lagoons are filled up soon, the total areas is about 60 km2 in 1990. All offshore bars are now connected with land except the Waishianting. The geomorphological change of liman coast affect human being deeply.



Key words ： Liman coast, Southwestern Taiwan
