本研究以九份爲例，探討影響傳統聚落「觀光發展容許量」之因素，並以景觀意象爲衝擊參數，建立容許量評估模式。研究結果顯示遊客認知使用量、實際使用量、過度使用環境現象及新商店密度均影響九份地區之景觀意象。此外，四個遊客調查地點之景觀意象與傳統聚落所應顯示之理想景觀意象有顯著差異，尤其基山街A段被認爲商業氣息過分濃厚。依此研究結果，遊客知覺到的環境過度使用現象對於景觀意象改變之影響極大，因此經營管理者必須改善九份地區之實質環境品質，以提供傳統聚落高品質之遊憩體驗。

This study explores the factors which affect tourism development capacity of vernacular settlement and establishes a capacity evaluation model with landscape image as the impact parameter. Jeou-Fenn is the empirical study site. Study result shows that visitor reported amount of use, actual amount of use, perceptions of overuse impacts,density of new buildings are related to landscape images of Jeou-Fenn. In addition, landscape images of four visitor survey locations deviated from ideal vernacul ar settlement images provided by a survey of 30 graduate students. Section A of Chishan road is perceived as over commercialized than a vernacular settlement should have According to the result, perceptions of overuse impacts will change landscape image significantly The managers should improve physical environment quality and manage visitor behaviors to provide high quality experience of vernacular settlement.
