Abstract: Soil physical characteristics were investigated in three sampled sites with different disturbance (tourism road, highroad and burning) in Bipengou ecotorism area, Sichuan. All of the three disturbances decreased soil water content, although soil water content was higher in soil surface layer compared with the deeper layers. Soil surface layer was looser and less hardening than the deeper soil layers. Trample could reduce soil porosity, and induce soil harden in surface layer. Soil porosity was also higher in soil surface layer than that in deeper layers, but soil gravel content was higher in the deeper soil layers.
