Abstract:
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 71.30//oo 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 mini mums 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 sign!ficantly richer than that in the restoration and rehabilitation of degraded ecosystem. There were certain difference in insect diversity between different kinds of degraded eco
