中文摘要	在不同季节对金沙江干热河谷鹤庆段4种类型退化生态系统恢复中昆虫群落采用样带调查法进行了调查．共采集昆虫标本7351号，158种．结果表明，退耕还林地和灌草丛昆虫多样性较低，灌木林和针阔混交次生林昆虫多样性较高．4种类型退化生态系统雨季昆虫群落物种丰富度、多样性指数和均匀度指数高于干季，优势度指数低于干季．不同类型退化生态系统在不同季节昆虫群落优势类群和优势种存在差异．退化生态系统恢复过程中昆虫物种多样性受到群落植被组成与受干扰程度影响．某些优势昆虫类群可能对退化生态系统的恢复有一定阻碍作用．在金沙江干热河谷地区营造灌木林，对于保护昆虫物种多样性具有积极意义．
英文摘要	The diversities of insect communities of 4 kinds of degraded ecosystems in Arid-hot Valleys along Heqing Reach of the Jinshajiang River were studied. 158 species were found in the 7351 captured specimens. The results indicated that the maximum of species diversity index and evenness index were found in the natural secondary forest, and the minimum of predominant index as well. The species diversity of insect community in the shrubbery was higher than that in the reforest land and the scrub and grass dump. Species richness, diversity indices and evenness indices in each degraded ecosystems in the rainy season were higher than those in the dry season, while predominant indices were lower. Predominant orders and predominant species were different among the different degraded ecosystems and between the rainy season and the dry season. During the degraded ecosystems restoring, species diversity of insect communities in those ecosystems was influenced by the vegetation components and the degree of disturbance that the ecosystems were received. Maybe certain predominant insects could impede the restoration of the degraded ecosystems. It was active for insects species diversity preservation that foresting shrubbery in the Arid-hot Valleys along the Jinshajiang River.
