Abstract:

By means of research method of the comparative sample investigations, the indexes of plant species diversity, species evenness, species richness, cover degree and root system biomass of shrubs in the four typical scenic spots (Wuyi palace, Dahongpao, Longchuan falls and Tianyou peak) of Wuyi Mountain were investigated and analyzed, and the effect mechanism of tourist activity on shrubs is also researched. The results showed that tourist activity has a significant effect on the plant species diversity index of the shrubs except Shannon-Weiner evenness index,while on the roots system the effect of biomass is insignificant. Moreover, the indexes of the plant species diversity, cover degree, total root and fine root system biomass in disturbed districts are all below non-disturbed ones. Furthermore, the disturbance rate of the shrubs in the four scenic spots is in the following orders. The order of the plant species diversity index is: Wuyi palace > Tianyou peak > Longchuan falls> Dahongpao; the cover degree is: Dahongpao > Wuyi palace > Tianyou peak > Longchuan falls; the total root system biomass is: Tianyou peak > Dahongpao> Longchuan falls > Wuyi palace; and the fine root system is: Tianyou peak > Longchuan falls > Wuyi palace> Dahongpao.

Key words: plant species diversity, root system biomass, shrubs, tourist activity, Wuyi Mountain scenic spot
