中文摘要	于2005年对云南元谋干热河谷新银合欢林昆虫群落进行了调查.结果表明：该区新银合欢林昆虫12目54科132种,其中68种已知种的名录;新银合欢林乔木及灌草层亚群落昆虫物种丰富度、Shannon-Wiener指数、Simpson指数及Pielou指数分别为98、3.588、0.050、0.783,地表层亚群落昆虫物种丰富度、Shannon-Wiener指数、Simpson指数及Pielou指数分别为49、3.255、0.053、0.836;新银合欢林容纳昆虫种类及个体数量的能力低于当地广泛分布的明油子-扭黄茅灌草丛,而其昆虫多样性水平与后者接近.研究认为,新银合欢林对于一些善飞的昆虫类群具有积极的保护作用,允许一定面积的新银合欢林存在将有利于当地生物多样性的丰富,但如果大面积广泛种植,则对于当地生物多样性的保护不利.
英文摘要	The arthropod community of Leucaena leucocephala plantation in Yuanmou Arid-hot Valley was investigated in 2005. 132 species were reported, including 12 orders and 54 families, among which the list of 68 known species was given. In the plantation, the species richness, Shannon-Wiener index, Simpson index and Pielou evenness index of the sub-community in the tree-shrub-grass layer were respectively 98, 3. 588, 0. 050, and 0. 783, and those of the sub-community in the litter-layer were 49, 3. 255, 0. 053 and 0. 836. Without the damage of chemical control, the natural enemies had active effects at the control on phytophagous pests. The ability to accept insect species and individuals in Leucaena leucocephala plantation is lower than that in Dodonaea angustifolia- Heteropogonetea contortus scrub and grass clump, which is widely distributed in the local. However, the insect diversity of the former is close to that of the latter. The study also shows that the plantation has protective effects on flying insects. Planting Leucaena leucocephala in certain areas helps to enhance local biodiversity but planting it in a multitude of areas does harm the biodiversity.
