本研究主要目的是：（1）探究太魯閣國家公園遊客所具備的環境素養；與（2）探求影響環境行動意圖的最佳變項組。研究者於太魯閣國家公園管理處的遊客中心以隨機取樣的方式訪問遊客，共得到有效問卷數430份。逐步迴歸分析結果顯示，影響環境行動意圖最佳的一組預測變項，依序為環境責任感、環境態度、對遊客行為後果的知識、土地之愛、對國家公園遊客行為相關法令的知識、及內控觀（Total R2=397）。最後再根據研究結果，對太魯閣國家公園的環境解說及後續研究提出建議。

The major purposes of this study were: (1) to assess environmental literacy held by the visitors at Taroko National Park; and (2) to analyze predictors of their intention to act environmentally. The visitors were randomly selected at the main visitor center of Taroko National Park. The effective sample size was 430. As a result of stepwise multiple regression analyses, the most parsimonious set of predictors of intention to act environmentally were environmental responsibility, environmental attitudes, knowledge of consequences of visitor behaviors, love toward the motherland, knowledge of national park laws, and internal locus of control (Total R2 = .397) . According to the research results, implications for the development of environmental interpretation at Taroko National Park were presented. Recommendations for further research were also provided.
