Soil is an important element of physical environment in tourism areas and also a main object of tourism impacts.This paper researches the level of soil environmental responses to the impacts of tourist activities in the Jinyun mountain of Chongqing by studying the soil single-factor change rate and the soil environmental response index based on field investigation and experimentation.The results indicate that

due to the impacts of tourist activities

soil water

soil porosity

soil clays

soil organic matters

total nitrogen and available nitrogen of all the samples averagely decrease by 22.79%

42.03%

40.31%

39.76%

37.99% and 30.87% in comparison with the contrasting spots;its pH and bulk density averagely increase by 6.59% and 56.64%;the change rates of soil total phosphorus

available phosphorus

total potassium and available potassium in all samples have not any significant relations to the impacts of tourists activities.The soil environmental responses indexes constitute a high-to-low cline successively from the whelk cave resort(4.655)

to the eight-cornered well trail(3.386)

the firry garden(3.289)

the No.308 factory-the bamboo trail(1.433) and the baiyun bamboo resort(1.264)

and their response levels are influenced by the intensity of tourist activities and the attribute of the soil.
