Based on the methodology of time-geography, this paper attempts to discuss the relationship between the activities of high mountain vegetable farmers and the cultivated environment. Through literature review, participating observation and interviewing, the research has recorded the time-space allocation of the land use activities in Nan-shan tribe and found out how vegetable farmers set up the sequence of cultivating management and employee organizations. In additions, the differences between the aborigines and non-aborigines in the time-space allocation of the land use activities has been analyzed as weIl. The survey results indicate that the vegetable farmers conduct a series of working activities, inclusive of seeding, land-mending, planting, irrigating, fertilizing, spraying and harvesting. During the period of harvest, due to the demand of labor, regular employee organizations including planting team, fertilizing team and harvesting team are formed. Besides, during the period of survey, another special task force form of employ organization named pulling vegetable team was formed because of the strike of typhoon Hai-Tang. The research results explain that the agricultural activities of vegetable farmers and employees are not only related to space movement but also consumption of time. What can not be separated is the interaction of time and space in the series of activities. The tradition way of working with the sunrise and resting with the sunset is no longer a life model for the vegetable farmers in Nan-shan tribe. The special agricultural forms, the so called - 'firefly', farmers and employee culture, have taken its place.
