摘要：采用样带调查法研究金沙江干热河谷鹤庆段不同类型退化生态系统恢复中昆虫多样性的变化。结果显示:(1)采获昆虫标本4 648号,计115种。其中同翅目昆虫占71.3%,膜翅目、半翅目和直翅目昆虫分别占10.1%,6.8%和4.2%,其余11目合计占7.6%。(2)天然次生林区优势度指数最低,多样性指数和均匀度指数最高;退耕还林地优势度指数最高,多样性指数和均匀度指数最低;封山育林区和天然次生林区物种丰富度指数高于其他样地。各样地之间昆虫群落相似性水平较低,优势种及常见种的种类和数量不同。(3)数量较大的害虫种类有蚜虫、蚧虫、云南蝗和鼻盾蝽等。(4)不同类型退化生态系统在恢复中昆虫多样性存在一定差异,退化程度较轻的天然次生林中昆虫多样性明显高于其他生态恢复与重建中的退化生态系统。
The diversities of insect community of different degraded ecosystems in Arid-hot Valleys along Heqing Reach of the Jinshajiang River were studied. The results were as follows：Fifteen orders of insects were found in the 4 684 captured specimens,of which 71.3% were in Homoptera and 10.1% were in Hymenoptera,Hemiptera and Orthoptera were 6.8% and 4.2% respectively and those in the other 11 orders all together were less than 8.0%. 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 minimum of species diversity index and evenness index were found in the reforest land ,and the maximum of predominant index as well. There was the same species richness between the hill-closing forest and natural secondary forest, which was higher than the others. For the composition of insects, the similarity coefficients were almost at an extremely dissimilar level among those plots. The minimums of similarity coefficient were between the natural secondary forest and the rests. There were different species and individual of predominant species and common species among those plots. This investigation that the numbers of some pests were nearly great. Those were Leucapsis sp. , Aphis sp. , Coccus sp. , Thoracaphis sp. , Yunnanites coriacea and Hotea curculionoides （Herrich-Schaeffer）. The studies showed that the insect diversity in natural ecosystem was significantly richer than that in the restoration and rehabilitation of degraded ecosystem. There were certain difference in insect diversity between different kinds of degraded ecosystem during their restoration and rehabilitation.
