2012年6月对茂兰喀斯特2种森林湿地土壤动物群落进行了调查。结果共获得土壤动物6 909只,分别隶属于3门11纲31目,其中优势类群为真螨目、蜘蛛目、鞘翅目、膜翅目,占总捕获量的58.72%;常见类群17类,稀有类群10类。多样性分析表明,土壤动物群落多样性指数和均匀度指数为板寨溶洞湿地最大,类群数和个体数最大为陇用沼泽湿地;土壤动物功能类群在数量比例关系表现为腐食性土壤动物最多,其次为植食性土壤动物,捕食性土壤动物最低。
In June 2012, soil animal communities in two forest wetlands of Maolan Karst were investigated. Results A total of 6 909 soil animal species were found, belonging to 3 orders, 11 classes and 31 orders, respectively. Among them, dominant groups were Acarina, Araneae, Coleoptera and Hymenoptera, accounting for 58.72% of the total catch; Rare group of 10 categories. The diversity analysis showed that the diversity index and evenness index of soil animal community were the largest in Cassia cave wetlands, the largest number of groups and individuals were Long-marsh wetlands; the functional groups of soil fauna showed the largest proportion of the number of rotting soil animals, Followed by herbivorous soil animals, predation of soil animals the lowest.
