合歡山地區為國內少數能夠提供遊客賞雪機會之旅遊據點，每當雪季往往擁入大量人潮，對遊客遊憩體驗品質造成衝擊。本研究之主要目的為探討合歡山雪季遊憩使用量對遊客擁擠感受之影響情形，以評估合歡山雪季期間之社會心理容許量。研究中將擁擠感分為進入區內時之交通擁擠感受、使用停車設施時之擁擠感受、對當下遇見人數之擁擠感受及使用公共廁所時之擁擠感受四個方面進行探討，分別建立全區遊憩使用量與遊客擁擠感受之函數關係，並與經營管理者進行訪談以決定評估標準，最後提出合歡山地區經營管理之參考使用量。研究結果顯示，雪季期間每半小時約可開放 263 輛車進出合歡山地區，而區內總車輛應維持在 350 輛車左右，建議經營管理單位可採用車輛管制方式控制合歡山地區之遊憩使用量。

The Hehuan Mountains area is one of the few snow-scene spots in Taiwan, and it provides the opportunity for visitors to experience the snow scene. However, it would impact on visitors’ experience quality when visitors crowd this area. The main purpose of this study was to examine the effects of the recreational use level on the perceived crowding of visitors, and evaluate the social psychological carrying capacity during the snow season in Hehuan Mountains area. First, this study divided the perceived crowding into five categories, including the traffic, parking facilities, the amount of visitors nearby, and using public toilets. Second, this study set up the mathematic relationship between the recreational use level in the whole area and the perceived crowding of visitors. Third, this study interviewed the administrators to determine the standards of quality. Finally, this study suggested the reference capacity for Hehuan Mountains area. The result of this study shows that the flow of vehicles should be limited to 263 cars in every half an hour during the snow season, while the total vehicles in the area should be restrained under about 350 cars. This study suggests the managers could use traffic control to restrict the recreational use in Hehuan Mountains area.
