    Abstract: 摘 要
    本研究之目的在於利用有限項目的監測儀器提出一監測沿岸水質環境產生劇烈變化之方法,此方法須能做即時應變之用,並探討該方法之可行性並探討桃園觀新藻礁海域之水體環境背景基線之特性,以便將來建構近岸的生態環境之即時監控系統。
    為此,本研究在大潭電廠進水口處堤防上建立一水質監測站,設置水質儀,平均每小時一筆之數據,輔以航測數據與岸邊採集分析水體中的溫度、鹽度、pH值、溶氧、葉綠素、濁度與營養鹽物質等項目,記錄2015年1月28日至2017年5月31日之數據,再搭配氣象資料(如:降水量、風速)來探討藻礁生態之水體環境受到颱風等極端天氣因子的影響時產生的變化;並嘗試以pH值與溶氧以及葉綠素與濁度兩組水質項目進行相關性分析,設定70%的信賴區間,假定當水體偏離區間時,即有可能為異常狀況發生,藉由此方法可提供警示並做進一步詳細分析來確認。
    ;Abstract
    In this study, we use a monitoring instrument of limited projects to propose a method to monitor the dramatic changes in the coastal water quality environment; This method must be used for immediate response, and explore the feasibility of the method, we recorded the high temporal resolution biogeochemical data to characterized the normal condition of algal reef area. This achieve will help to establish a real-time monitor system for the quality of near shore ecology.
    Thus, we set up a water quality monitoring station on the embankment at the inlet of the Taitan Power Plant, and analyze water sample to monitor the biogeochemical parameters in this algal reef area. From January 28, 2015 to May 31, 2017, we collected biogeochemical data including Temperature, Salinity, pH, Dissolved oxygen, Chlorophyll, Turbidity and Nutrients. We also compare meteorological data (Precipitation and Wind speed) to explore the changes in the water environment of the algae reef ecology caused by extreme weather such as typhoons; And we attempted to analyze the correlation between pH with Dissolved oxygen and Chlorophyll with Turbidity water quality items, and set a 70% confidence interval. It is assumed that when the water deviates from the interval, it may be an abnormal situation. Provide warnings and make further detailed analysis to confirm.
