本研究旨在暸解大學生的健康概念、環保意識、蔬食行為及其相互之間的關係，以及大學生的健康概念與環保意識對蔬食行為的影響。經過問卷調查與分析，所得之結果與研究假設大部分相符，也能解釋研究對象之蔬食行為背後的影響因素，突破以往認為採取蔬食是因為宗教信仰，也侷限於中老年人的觀念，導入健康概念與環保意識，讓國人在飲食的選擇上，能有更寬拓的視野與考量。依據分析結果顯示，大學生的健康概念可分為安寧幸福與調適二層面，環保意識可分為環境關懷與環保行動二層面，而自覺安寧幸福的人，也較具自我調適與環境關懷的意識，同時也較會採取環保行動及蔬食行為，自我調過能力好的人，對環境也較為關懷，也採取較多的環保行動與蔬食行為，較具環境關懷意識的人，也比較會採取環保行動與蔬食行為，環保行動較多的人，採用蔬食行為的行動也較高。但是從個人背景變項來看，僅能發現經常蔬食的人比幾乎不吃蔬食的人，對蔬食行為的感受較佳，因為其他理由而不願蔬食的人，也比認為蔬食會造成營養不均衡的人，對蔬食行為的感受較佳，性別在此並未造成明顯差異。傳統觀念均認為女性比男性更具健康概念與環保意識，也會採取更多蔬食行為，但從本研究的結果卻無發現此差異，有可能是時代的變遷與教育水準的提升，使得此差異日漸縮小，但是在提升蔬食行為上，是否能有更有效的策略，則值得更進一步的探究。而本研究也建議應持續宣導蔬食行為能帶給健康與環保的正面效益，並鼓勵學校或周邊商家能多提供蔬食餐點，相信這樣對於提升大學生的蔬食行為含有所助益。

This study aimed to understand the health concept, environmental protection consciousness, and vegetarian of college students. The health concept can be divided into two levels, one is peace and happiness and another is adaptation. The environmental protection consciousness can be divided into two levels, one is environmental concerns and another is environmental action. The people who feel more peace and happiness have more self-adjustment and awareness of environmental concerns and take more environmental actions and behavior of vegetarian. The people who have self-adjustment ability care more the environment, and take more environmentally friendly actions and behavior of vegetarian. The people who have environmental protection consciousness adapt more environmental action and behavior of vegetarian. The people who have more environmental action take more behavior of vegetarian. From this study, the behavior of vegetarian in male and female have on difference. We suggest the authorities should advocacy the importance of vegetarian can bring health and environment benefits, and encourage schools and businesses to provide more vegetarian food. I believe that will be helpful to enhance the behavior of vegetarian in college students.
