Abstract: 摘要:長期監測墾丁國家公園海域珊瑚礁環境生態,監測區涵蓋貓鼻頭、香蕉灣及龍坑三處生態保護區、海域生態保護區及一些非保護區、後壁湖與眺石海洋資源保護示範區,針對人為活動對海域生態衝擊影響進行長期之調查研究,分析各因子間相依共存、相生相剋之因果關係,期望找出影響墾丁海域珊瑚礁生態之重要環境因子,並研擬解決對策,提供決策單位作為參考。 本研究結果顯示,墾丁國家公園附近沿岸海域部分測站含有較高的營養鹽及懸浮固體,其來源主要分別是保力溪、墾丁大排、凱撒小排及石牛溪等人為活動排放溝渠。降雨及颱風將河床之沈積物所吸收累積之耗氧性污染物質沖刷至沿岸水域,再加上每年大量遊憩人潮,也直接間接影響整個墾丁沿岸海草床與珊瑚礁海域生態環境。以MDS分析結果發現,萬里桐海域的魚類組成明顯與其他測站不同,軟體動物群聚各地區相似度僅有20%,相似程度不高,顯示各地海岸群聚有所差異。依r-K-S保育等級分類分析結果,紅柴已進入保育等級=1的保育等級,以抗環境壓迫能力高的珊瑚為優勢,顯示此區以遭受嚴重的沈積物、泥沙等污染。而、萬里桐、雷打石、香蕉灣與龍坑都屬於保育等級=4,有機會成為珊瑚礁魚類輸出區,需優先投入保育工作的礁區。此外,利用資訊技術從數值化、量化的資料中,並萃取出有趣、有用的知識,透過直覺性的呈現,搭配線上模式模擬系統,將所開發之墾丁模式發佈於網路,提供線上模型操作,支援決策導向的整合型資訊系統與提供管理者進行決策分析之依據,使相關決策者瞭解生態系運作,在制定相關政策與環境規劃,減少對環境的負面影響,落實自然資源保育,以達永續發展的最終目標。
Abstract:Since July 2001, National Museum of Marine Biology & Aquarium (NMMBA), under the support of Kenting National Park Headquarters, conducted a Long-Term Ecological Research (LTER) monitoring program on the impacts of human activities to marine ecology. National Taiwan Ocean University (NTOU) continues this study; monitoring programs include sewage discharges, habitat destruction (sedimentation), overfishing, and eutrofication of seagrass beds, while coral reef mapping and database establishment were carried out. Data were analyzed from different sites around Nanwan Bay from 2001 to 2010. Some major findings were that the seawaters of intertidal zone along Nanwan Bay were polluted by sewage discharge at some monitoring stations, evidence by eutrofication, high chlorophyll a concentration, high BOD5, high turbidity, and high pH values. The suspended solids in Kenting seawater mainly came from seasonal rainfalls and partially caused by typhoons which had affected the health of seagrass beds and coral reefs. The results of MDS and Cluster analysis indicate fish composition were much different between Wanliton and other sampling sites around Nanwan Bay. Generally, the similarity of mollusca between different sampling sites around Nanwan Bay was only 20%. Besides, the database of ecological modeling has been established, so it can integrate the research datum and predict the impacts of human activities to the Kenting marine ecology. Consequence, this project can find solutions for the impacts of human activities mentioned above on marine environments and to provide information for the authorities. The public can then be more concerned about the issues on environmental protection and ecological conservation, and the government can then take appropriate actions to control the coastal development more effectively and to reverse the current deteriorating situation.
