Abstract: Village has the characteristics of landscape disturbed by human's activities.It is a very good object to deplore the effect of human disturbance on landscape fragment.Based on vegetation change and major auxiliary energy input,the disturbance was divided into three levels,e.g.,strong,moderate and slight disturbances.Accordingly,the village environment was divided into three zones,center zone,transition zone and base zone,and the relationship between landscape fragment and human disturbance intensity was analyzed for each zone.The results showed that the total patch density indexes in three zones were 0.3416,0.3109 and 0.0028,and the landscape fragment indexes in three zones were 0.0820,0.0746 and 0.0007 respectively.Landscape fragment was closely related to disturbance degree,and stronger disturbance result in higher landscape fragment indexes.Moreover,there existed high landscape fragment indexes under moderate disturbance.
