本研究主要以「遊憩體驗」、「對解說步道之認同程度」、「對管理國家公園之態度」以及「學習效果」四個構面做為本研究測量解說效果之指標，藉以探討不同遊客特性使用解說步道後，解說效果是否具差異性；以及探討遊客在使用解說步道的過程中使用解說牌，對其解說成效之差異性如何。研究結果顯示，遊客特性會影響遊客使用步道之解說效果；解說牌之使用與否會因遊客特性的不同而有顯著的差異；且遊客在遊憩體驗向度中的「情感與壓力之紓解」；使用認同程度向度中的「解說牌之認同」與「使用成效之認同」；管理國家公園態度向度中的「國家公園所規定事項」，以及學習效果，會因遊客對解說牌之使用而有顯著的差異。本研究建議主管機關在規劃步道時，除加強遊客對步道使用的認同感與學習效益外，在增建設施時，除考量遊客效益外，對於環境資源開發與保育間的平衡，更應審慎的評估，以維繫遊客高品質的遊憩體驗為依歸。

This study explored the effectiveness of Skadang interpretation trail through four aspects of measurements, including (1) visitors' recreation experience; (2) visitors' commitment toward the interpretation trail; (3) visitors' attitude toward the management of National Park ; and (4) visitors' learning effectiveness. The results indicated that visitors' characteristics were significantly related to interpretation effectiveness. With respect to the effectiveness of interpretation signs, whether visitors' use of interpretation signs or not was significantly related to visitors' characteristics, the relaxation of emotion and pressure, the commitment of interpretation signs, use effectiveness, attitudes toward national park regulations, and learning effectiveness. This study suggests that government agency not only needs to reinforce visitors' commitment and learning benefits while planning the interpretation trail, but also have to take both environmental resource development and resource preservation into consideration for mutual balance so as to maintain high quality of recreational experience for park visitors.
