<正>通过植物分子式的方法确定不同村种的分碳量，以此为参数对我国的森林碳汇量进行了估算。结果表明：该计量方式既简单易行，叉具有规范性及重复操怍L生，可动态预测我国森林碳汇量。并且，通过我国几次森林资源清查数据和森林货源系统c亏真模型+该h-法可对栽国森林碳汇功能发展趋势作出动态预测。

Heteroptera diversities in 7 plantation communities were surveyed using sample plot investigation method in Yuanmou Arid-hot Valley. Yunnan. 928 Heteroptera individuals of 45 species were collected. The specie richness, Shannon-Wiener index and Pielou index were the highest, but Simpson index was the least in Pinus yunnanensis and Azadirachta indica plantation. While these indexes were the contrary with above two plots in Dichotomanthus tristaniaecarpa-Vitex negundo natural regenerated forest. Results showed that measurment of natural regeneration had actively effect on Heteroptera diversity in the habitats severely degraded in Yuanmou Arid-hot Valley. The habitats of 7 investigated plots are different each other.
