2014年5—10月,对茂兰喀斯特森林湿地地表节肢动物群落结构进行了研究,通过手拣法、陷阱法对获得的地表节肢动物进行分离、分类.结果显示,采集的4777只地表节肢动物隶属9纲26目27类,其中优势类群3类(蜘蛛目、鞘翅目和膜翅目),常见类群15类,稀有类群9类.各湿地地表节肢动物类群数和个体数无显著差异(P>0.05).多样性分析表明,地表节肢动物群落个体数、类群数和丰富度指数最大值均出现在洞弓沼泽湿地,Shannon多样性指数和均匀度指数板寨溶洞湿地最大.%Ground arthropods in the wetland of Maolan karst forest were investigated from May to October in 2014, and 4777 individuals that belong to 9 classes, 26 orders and 27 groups were collected. Dominant groups included 3 groups ( Arachnida, Coleoptera and Hymenoptera) and 15 common groups and 9 rare gourps were also surveyed. The number of groups and individual of ground arthropod had no significant difference among the 5 forest wetlands( P>0.05) . The maximum value of the individual number, the group number and the rich index of soil arthropod community all appeared in Donggong marsh wetland; the maximun diversity value and the evenness index appeared in Banzhai cave wetland.
