二零一五年二月,立法院終於通過了延宕二十餘年的海岸管理法。其中第14條指出海岸災害如:海岸侵蝕,洪氾溢淹,暴潮溢淹,地層下陷或其他潛在的災難,中央或地方政府應視不同情況制定相關的管理計劃。又因第44條,中央及地方政府需於二年內公告海岸管理計畫,因此彰顯了此法對海岸環境保護之重要性及急迫性。本研究區域位於台南沿海,透過地理資訊系統(GIS)和數位海岸線分析系統(DSAS)(Thieler et al., 2009)觀察海岸線的長期變化,說明台南沿海岸地區侵蝕及淤積的情況。 本研究使用了航照圖、地形圖以及衛星影像圖等影像資料,監測從1974年到2013年,共37年的海岸線。再用統計的線性回歸率(LRR)方法來量化台南海岸線的變化。結果顯示台南北部及中部海岸幾乎全面處於侵蝕的狀態,其中中部的七股潟湖沙洲侵蝕最為嚴重;相反,南部的新浮崙沙洲鄰近地區的結果顯示為淤積。


The Coastal Zone Management Act (CZMA) of Taiwan was adopted in early 2015. This act is aimed at promoting the integrated management and sustainable development of coastal areas. In terms of the details this act, article 14 indicates that a coastal protection plan shall be formulated for coastal zone erosion, tide overflow, storm surge flooding, land subsidence, or other potential disasters, implemented by the central or local government. Additionally, article 44 indicates that central and local governments need to announce their coastal management plans within two years, which underscores the importance and urgency of coastal management planning in Taiwan. This research focus on a case study conducted in Tainan, located in the south-western part of Taiwan. Shoreline change was analyzed using geographic information system (GIS) and Digital Shoreline Analysis System (DSAS) models. Resources including aerial photography, topographic maps and satellite imagery have also been used to monitor shorelines change from 1974 to 2013. Erosion and accretion conditions were recorded to identify shorelines using a statistical method called the linear regression rate (LRR). The results of the LRR suggested the Tainan coast was largely in an erosion phase. The most serious situation occurred in the sandbars of Cigu Lagoon, located in the middle of the Tainan coast. In contrast, the results suggested coastal accretion occurred along the Shinfulun sandbar and in the Sicao Wetland during the study period. An image processing method was developed to identify the suspended sediment distribution (SSD) at an instantaneous time. It was verified by comparing results with survey data from the study area. The SSD helps explain the reasons for coastal change in Tainan.

Daily satellite image derived from FORMOSA-2 were analyzed to illustrate the gradient magnitudes and directions of suspended sediment (SS). The results demonstrated that in alternative flood or ebb, the gradient directions revealed a generally westward/northwestward transport, which suggested that the offshore-ward transport of SS is likely one of the major factors in coastal erosion. In addition, these results revealed that sediment discharged from the Tsengwen River moved northward and eastward and accumulated south of the Cigu seawall. This movement therefore caused Shinfulun sandbar accretion in the north estuary of the Tsengwen River. In conclusion, the decrease in the southward supplementation of SS from northern Tainan City is likely be the crucial factor resulting in erosion along the Cigu lagoon.
