本研究主要目的在探討社區聯繫力與觀光遊憩活動對於原住民部落之衝擊影響。研究範圍為鄰近太魯閣國家公園，主要居民為太魯閣族群之可樂部落為探討主體，調查方式是在社區內以逐戶問卷調查方式進行，總計回收85份居民問卷。 研究結果將觀光衝擊認知以因素分析區分為四個因素構面，再利用結構方程模式分析獲得社區聯繫力構面與觀光衝擊構面之間的關係模式，以驗證研究假設。結果發現本研究三項假設均獲得成立： 1.觀光衝擊認知會因居民社區聯繫力的不同而有差異，特別是促進文化與建設及經濟活動影響因素構面，當社區聯繫力越高時，其認知程度會越明顯 2.社區聯繫力會因居民屬性不同而有所差異 3.觀光衝擊認知會因居民屬性不同而有所差異 並針對研究結果提出相關建議與後續研究方向提供相關單位與社區發展組織未來在研擬規劃發展策略時，做為參考之用，針對社區的聯繫力制訂其社會承載力以降低觀光發展衝擊影響層面。 【關鍵字】社區網絡、社區聯繫力、觀光衝擊 Abstract In recent years, tourism development has been thought as an instrument to improve the local economy and community residents’ standard of living.
