Abstract:

[Objective] : In order to understand the impacts of tourism disturbance on plant community in Taimu mountain scenery district, the characteristics of plant community were analyzed in different distances from tourist routes. [Method] : Several indicators including sensitive level, community landscape importance value, information index of species diversity and Tourism impacting index were investigated and calculated to survey the effects of tourism disturbance intensity on plant community.[Result] : The sensitive level in each vegetation layer at different distances from tourist path showed the same order as, close >middle > distant, indicating that the tour frequency is significantly high nearby scenic spots. However, the importance value of community landscape showed the order as middle >close > distant, which suggested that the middle distance had higher tourist value and good environment quality. The closely relationship was observed between Level distance and information index. The nearer the distance from tourist routes is, the smaller the information index could be. According to the tourism influence coefficient evaluation classification, the management level of the scenic area could be evaluated in the good level. [Conclusion]: Theses results could provide useful scientific data for managing the scenery district.
