摘　　要：对贵州省黎平县退耕还林不同配置模式下植被生物量进行定量对比和定性分析。结果表明:杉木生物量较大,是当地退耕还林保持水土的先锋树种;亮叶含笑林下草本层生物量最大;麻栎和马尾松林下枯落物生物量积累较多,能够发挥较大的水土保持效果。The quantitative comparison and qualitative analysis were conducted to the vegetative biomass in different configuration modes for reforestation of cultivated land in Liping County of Guizhou Province.The results showed that Cunninghamia lanceolata is the pioneer tree species for soil and water conservation because its biomass is relatively larger;Michelia fulgens forest has the highest biomass in its herb layer;the forest of Quercus acutissima and Pinus massoniana has relatively higher biomass in its litter layer,which can play a significant role in soil and water conservation.
