摘要
From July to September in 2005, the resources of Staphylinidae in four types of human disturbance regions ( human gathering area, grain for green re- gion, grazing region and rare disturbance region) in Erlang Mountain, Sichuan were investigated, and the individual number, species composition and diversity characteristics were analyzed. The result showed that the individual number, species diversity index (H') and the evenness index (J) decreased with the decrea- sing intensity of human disturbance. The species diversity index and the evenness index in human gathering area were the highest of 4.1301 6 and O. 850 2, respec- tively. Simpson predominant index (A) enhanced with the decreasing intensity of human disturbance, which reached the peak of 0. 199 6 in rare disturbance re- gion. The community similarity index/3 of Staphylinidae at different human disturbance regions ranged from 0 -0.25, indicating that the species compositions were extremely different among this four types of regions. Based on these results, it was found that human activities were closely related to individuals number and species dive^ity of Staphylinidae in Erlang Mountain, and human disturbance may add habitat heterogeneity and facilitate to the species diversity of Staphylinidae communi- ties.
