摘要
采用国际通用采样方法,在秋季对兴隆山实验区边缘地带7个样点土壤动物群落进行调查研究,比较分析土壤动物群落组成、多样性、垂直分布特征。结果表明:1共捕获土壤动物390只,隶属于3门5纲6目18类,其中优势类群为弹尾目、真螨目、双翅目幼虫,占总捕获量的77.69%。2土壤动物群落结构与多样性存在差异,H'为1#>4#>5#>2#>7#>6#>3#,C为3#>6#>7#>2#>5#>4#>1#。3不同样点土壤动物的垂直分布具有明显的表聚特征,即随着土壤深度的增加土壤动物类群数和个体数量逐渐减少。研究结果为进一步开展保护区土壤动物生态学研究提供了基础资料。
For understanding the characteristics of community structure, diversity and vertical distribution of soil animal at 7 plots in fringe areas of Xinglong Mountain National Nature Reserve, an investigation was conducted in autumn by field sampling method. Results are as follows ： 1 ） A total of 18 groups and 390 soil animal were captured, belonging to 3 phylas,5 classes ,6 orders. The dominant groups of soil animal included Collembola, Acariformes, Diptera accounted for 77.69% of the total samples. 2） There were significantly variations in the composition and individuals of soil animal community. The order of diversity index H＇ in each community was 1^# 〉4^# 〉5^# 〉2^# 〉7^# 〉6# 〉3# ,C in each community was 3^# 〉6^# 〉7^# 〉 2^# 〉 5^# 〉 4^# 〉1^#. 3 ） The vertical distribution of the groups and individuals density in soil profile showed surface accumulation in the layer of 0 -5 cm and declined with depth increasing of soil layer. These results will provide useful data for ecological study of soil animal in Nature Reserve.
