本研究目的在瞭解休閒潛水參與者的海洋保育認知與海洋保育行為之現況，並分析不同背景變項在海洋保育認知與海洋保育行為上之差異情形，最後再探討海洋保育認知與海洋保育行為間之相關性與海洋保育認知對海洋保育行為之預測情形。本研究採用問卷調查法，研究對象為恆春核三廠出水口旁的休閒潛水參與者，以便利抽樣方式共發出問卷300份，回收有效問卷共256份，有效回收率為85%。所得資料經描述統計、單因子多變量變異數分析、典型相關、多元逐步迴歸等方式加以分析，所得結果顯示休閒潛水參與者之海洋保育認知與海洋保育行為有相關性，海洋保育認知能有效預測海洋保育行為。

The purpose of this study was to investigate the status of marine conservation cognition and marine conservation behavior of recreational divers; Besides, to analyze variable backgrounds in the differences between marine conservation cognition and marine conservation behavior; Finally, to explore the relationship between marine conservation cognition and marine conservation behavior, and to predict marine conservation cognition against marine conservation behavior. The research mothod in this study was mainly a questionnaire survey, the research members were those recreational divers next to the Hengchung Nuclear Plant outlet by random sampling structure. There are 256 valid questionnaires returned from 300 fore-sending pieces that effective return-ration is 85%. Data were analyzed by descriptive statistics, single factor multivariate analysis of variance, canonical correlation, stepwise multiple regression, etc. The results express as follows: Recreational divers' marine conservation cognition and marine conservation behavior have a positivecorrelation. Marine conservation cognition can effectively predict marine conservation behavior.
