Soil macrofauna, mainly in the soil surface horizon, are good indicators for studying the impact of human activities. In the present study, Yaoquan Mountain of Wudalianchi World Geo-park was considered as a study example in 2012. The areas surrounding tourism trails were divided into no-trampling, mid-trampling, and high-trampling plots, which were divided based on three different interference types. The effect of human trampling on soil macrofaunal communities at a depth of 0-10 cm were studied along an increasing distance from the tourism trail of Yaoquan Mountain. A completely randomized design, including three replicates from three trampling interference sites, was used. Soil macrofauna were separated by hand, and were identified and counted. Soil bulk density, soil moisture content, soil organic matter content, total nitrogen content, and total phosphorus content were measured from each site. Our study evaluated the structure, composition, diversity, and distribution of soil macrofauna in three different tourism trample types, and assessed the impacts of human activity. The results were summarized as the following aspects:The total number of soil animal genera was significantly different in the three disturbance degree sites (P<0.001) and the least number of genera occurred in high trampling sites. The individual density of soil macrofauna was significantly different from the other kinds of soil animal fauna in the three disturbance degree sites (P<0.001), the maximum value was in the mid-trampling plots (68 ind./m2), and the minimum value was in the high-trampling sites (10 ind./m2). The Shannon index (H') of soil micro-fauna were seriously affected by trampling (P<0.05), and the high trampling sites had the lowest H' index. A canonical correspondence analysis indicated the soil macrofaunal distribution in the mid-trampling and high-trampling plots differed from the no-trampling plots. The main factor affecting soil macrofauna distribution was soil total nitrogen content, soil moisture content, and total phosphorus content in no-trampling, mid-trampling, and high-trampling plots, respectively. 参考文献 相似文献 引证文献
