Soil animal is one of the most sensitive environmental factors in the scenic area ecosystem influenced by tourism activities, and also the focus of the ecological environment research. Six main trails were chosen and eight investigation belt transects have been set up in Mount Jiuhua scenic area. Each belt transect is mutually perpendicular with the location of trails. In each sampling belt, four sampling quadrats with different distances away from the trail were investigated. Under the layer of withered defoliation, each sampling quadrat was divided into four layers at an interval of 5cm along the vertical section. The macrofaunas in soil and the layer of withered defoliation were collected by means of hand sorting and boult. A total of 2076 individuals were found to belong to 27 orders, 8 classes, and 3 phyla. In comparison to Shannon-Wiener index (H') and gathering degree, the clusters and amounts of soil macrofaunas in different sampling layers of each sampling quadrat situated in different sampling belts were analyzed. The results are obtained as follows. (1) Soil macrofaunas of Mount Jiuhua scenic area were affected obviously by tourism activity, that is, the more the tourism activity is, the less the number of soil animals is. (2) The categories and amount of soil macrofaunas rose gradually with the increase of distance away from the trails. (3) Soil macrofaunas gathered obviously in surface layer of soil in the vertical section. Affected by tourism activity, the gathering degree of soil macrofaunas in surface layer increased in farther sampling quadrats away from the trail. (4) Different correlations were observed. The number of tourists showed a negative correlation with the quantities of soil macrofaunas of 01 and 02 sampling quadrats, and a positive correlation with the quantities of soil macrofaunas of 03 and 04 sampling quadrats. At the same time, this paper used a comparison method to discuss the macrofauna captured in Zheshan hill park and Mount Jiuhua scenic area at a similar latitude. Due to the impact of tourism activities, the distribution of macrofauna has the same law on the one hand and differences on the other hand due to different natural environments in these two places. It is found that, in both places along the trail to the inside, the macrofauna increase horizontally and become more concentrated vertically, and both of these phenomena are closely related to the intensity of tourism activity. Likewise, at the quadrats far away from trail, the distribution of macrofauna was slightly affected by tourism activity but strongly affected by natural environment factors.
