We took Yuntai Mountain scenic area of He’nan Province as the research site, and determined the soil physico-chemical properties, soil nutrients and heavy metal content under different intensities of tourist disturbance in order to investigate the effects of tourist disturbance on soil quality. The results showed that the soil moisture, porosity, clay and soil nutrients content decreased in the order:background area > buffer area > core area, and the soil bulk density and pH decreased in the sequence:core area > buffer area > background area. The soil moisture and nutrient contents declined, bulk density increased, porosity and clay declined with the increase of the intensity of the tourist disturbance. The soil organic matter (SOM), total nitrogen (TN), available nitrogen(AN) and available phosphorus(AP) contents of mountain top had the significant differences between different disturbance intensities (p<0.05). The soil moisture content of mountain side had no significant difference between background area and buffer area (p>0.05). Both were significantly higher than those in the core area (p<0.05). The SOM, TN, total phosphorus(TP), AN and AP contents in the background area of foot of the mountain were significantly higher than those in the core area and buffer area (p<0.05), but those had no significant difference between core area and buffer area (p>0.05).The contents of soil total chromium (Cr), cobalt (Co), manganese (Mn) and zinc (Zn) in mountain top and Cr, Co, Mn, iron(Fe) and copper(Cu) in mountain side decreased in the order:core area>buffer area> background area. Those heavy metal contents in the core area were significantly higher than those in background area and buffer area (p<0.05). The soil heavy metal contents in foot of the mountain had no significant difference between core area and buffer area (p>0.05) and both were significantly higher than those in the background area (p<0.05). The tourist disturbance has significantly (p<0.05) or much significantly (p<0.01) negative correlation with soil moisture, porosity, clay, SOM, TN, TP, total potassium (TK), AN, AP, available K. The tourist disturbance has significantly (p<0.05) or much significantly (p<0.01) positive correlation with soil bulk density, pH, contents of Cr, Co, Fe, Mn, Zn and Cu.
