中文摘要：

愉悦性作为旅游体验的本质近年受到不断质疑,有必要对其深入论述以便旅游学科基础理论发展。旅游愉悦性的必然性体现于旅游活动中存在审美活动（包括审美与审丑、喜剧与悲剧）、心理满足（需要-动机-行为-满足）和生理畅爽（感官刺激与肌体运动）能够促使旅游者愉悦的过程。旅游愉悦性并非仅仅是人们口语中的高兴（低级感官刺激）,还包括旅游者的高级心理需求;不仅包括对喜剧的审美（通常意义所理解的审美）,还包括对悲剧的审美（也可理解为审丑）;不仅包括通俗愉悦,还包括高雅愉悦。旅游愉悦中的低级刺激与高级需求、喜剧美与悲剧美、通俗愉悦与高雅愉悦是辩证统一的关系,不可孤立审视。

英文摘要：

Pleasure was once taken as an essential attribute of tourism,however,it was questioned with the development of tourism.It is necessary to discuss the question in order to promote the fundamental theoretical development of tourism.Tourism pleasure relies on tourism activity itself which contains aesthetic activity（no matter beauty or ugly appreciation,comedy or tragedy）,psychological satisfaction（need—motivation—behavior—satisfaction）and physiology flow（including sensory stimuli and body movement）,which can surely bring pleasure to tourists.Tourism pleasure means not only lower sensory stimuli of having fun,but also higher psychological need of being joyful.It appreciates not only comedy which is commonly known as beauty but also tragedy which is known as ugly;it refers to both popular pleasure and elegant pleasure.All of those elements coexist in dialectical unity so that one cannot view them unilaterally.
