旅游干扰对土壤动物群落结构与功能类群的影响——以黑石顶、九龙湖、北岭山为例

Changes of Community Structure and Functional Groups of Soil Animals under Tourism Disturbance——Taking Heishiding,Jiulong Lake and Northridge Mountain as an Example

对黑石顶自然保护区、九龙湖自然保护区和北岭山森林公园乔木下土壤动物群落结构进行调查,结果表明:1.共捕获土壤动物4004只,属3门9纲15目,优势类群和常见类群捕获数占总捕获数的93.18%.2.旅游干扰影响土壤动物的栖息环境,造成土壤动物群落结构发生变化.3.聚类分析结果表明,九龙湖自然保护区和北岭山森林公园土壤动物群落结构相近,群落间有较多的共同性.4.旅游干扰改变土壤动物的物种组成,捕食者的大量增多,间接影响凋落物分解和养分循环等生态系统过程.

The results of structure of soil animal conmmunity in Heishiding Nature Reserve, Jinlong Lake Nature Reserve and Northridge Forest Park under the tree layer were： 1） the captured 4004 soil animals belong to 3 phyla, 9 classes and 15 orders, of which the dominant groups and common groups of capture accounted for 93.18%; 2） the tourism disturbance affects the habitat of soil animals which causes the structural changes of soil animal community;3） cluster analysis results show that soil animal communities in the Jiulong Lake Nature Reserve and Northridge Forest Park have similar structure, which indicates that both of the two communities have much in common;4） tourism disturbance changes the species composition of soil animals and increases the number of predators, thus indirectly affecting the ecosystem processes such as litter decomposition and nutrient cycling.
