In this paper,effects of tourism disturbance on soil and vegetation were assessed by the use of paired seriously and slightly influenced plots on the peak,the mountside and the mesa of Bashilazi Mountain,the highest mountain in Erlong Mountain Scenic Region.Furthermore,the vegetables in Bashilazi Mountain and the Back Mountain were comparatively analyzed as a whole.The results showed that soil bulk density and pH value increased while the soil moisture content,soil porosity,organic matter,N,P and soil clay content decreased due to tourism disturbance.Serious tourism disturbance lessened the vegetable individuals,made species simple,decreased the diversity and evenness indices and increased the dominance index.The effects of tourism disturbance on grass and shrub layer were obvious,but were not so obvious on arbor.
