Abstract: As a large-scale prosperous industry, tourism has become more and more important in the world. At the same time, the problem of pollution and environment-wrecking have emerged with its development. As the most sensitive factor to disturbance, the soil, one of the significant parts of ecosystem, has a great impact on the stability of ecosystem and the health of environment. As mentioned above, the literature review is used in this paper. Firstly, the author illustrated three phases of researching process about the impact of tourist activity on soil environment, namely, the beginning stage, fast development stage and maturity stage. Secondly, the writer represented the different impacts of all tourist activities on the soil environment and summarized the characteristics of those literatures which have been published so far. Finally, the authors put forward some limitations as follows. (1) The rationality of the frame of reference in the papers that had been published should be reconsidered. (2) The content of research in this field should be extended; the researches about the impact of tourist waste on soil environment are still insufficient. (3) The limitation of these researches is that they are confined to locations in single beauty spot, while there are fewer studies of the impact of inter-regional tourism on soil environment, which make research lacking systematization. (4) The methods used in this field are relatively simple. The researches about spatio-temporal evolvements of soil environment under the influence of tourist activity are deficient. (5) The subject investigated is lack of diversity. The researches on ecological vulnerable areas such as wetland and tundra are insufficient. Considering the limitations above, the author put forward some prospects and development trends about this area so that it can help the research in future.
