本研究旨在探討山溪釣者在活動熱情、遊憩專門化與心流體驗間的關係。以從事山溪釣遊活動者為研究對象，共蒐集505份有效問卷，並以結構方程模型進行資料分析。結果顯示，活動熱情會正向影響遊憩專門化，但僅諧和式熱情會正向影響心流體驗，而強迫式熱情則會負向的影響心流體驗；此外，遊憩專業化愈高的山溪釣者，其得到的心流體驗亦愈高。此外，本研究亦針對研究結論提出若干管理意涵，期能提供政府相關單位及休閒產業在經營管理上的參考，並提出後續可朝向的研究方向之建議。

The purpose of this study was to explore the relationship among passion for activities, recreation specialization, and flow experience among mountain stream anglers. Using a sample of 505 mountain stream anglers in Taiwan, this study applies Structural Equation Model (SEM) to verify the proposed model. The result shows that both harmonious passion and obsessive passion had a positive effect on recreation specialization, but only harmonious passion could affect flow experience positively. Obsessive passion was negatively related to flow experience. In addition, the higher the recreation specialization, the higher the flow experience. Based on conclusions, this study proposed managerial implications for the authorities concerned and the leisure industry as well as suggestions for future researchers.
