摘　　要：于2005年对云南元谋干热河谷木豆林节肢动物群落进行了调查,结果表明:木豆林节肢动物有108种(39种待定),分属于2纲、10目、49科;蜡蚧、咖啡黑盔蚧、榄珠蜡蚧及豆蚜为植食功能群优势种,叉草蛉和云南斧螳为天敌功能群优势种,迈氏小家蚁和光颚铺道蚁为杂食功能群优势种;木豆林节肢动物群落Shannon-Wiener指数为2.662,Simpson指数为0.123,Pielou均匀度指数为0.569;植食功能群、天敌功能群、杂食功能群的物种丰富度分别为71、25、12,多样性指数分别为2.424、2.728、1.826,优势度指数分别为0.136、0.103、0.269,均匀度指数分别为0.569、0.848、0.735.An arthropod community in pigeon-pea woods was investigated in Yuanmou Arid-hot Valley in 2005. 108 species （39 to be identified） were reported including 2 classes, 10 orders and 49 genera. Results show that Coccidae, Saissetia coffeae, S. oleae and Aphis laburni are predominant species in the phytophagous functional group, Dichochrysa sp. and Hierodula yunnanensis in the natural enemy functional group, and Monomorium mayri and Tetrarnorium insolens in the omnivore functional group; that the community＇s Shannon-Wiener index is 2. 662, Simpson index 0. 123 and Pielou evenness index 0. 569% and that the species richness of the three groups are respectively 71, 25 and 12, their Shannon-Wiener indexes are 2.4Z4, 2. 728 and 1. 826, their Simpson indexes are 0. 136, 0. 103 and 0. 269, and their Pielou evenness indexes are 0. 569, 0. 848 and 0. 735.
