摘  要：
在云南省普洱市澜沧县选取7块3年生短周期巨尾桉工业原料人工林样地和7块其原生林对照样地,对其林下灌木层和草本层进行了调查,依此对其多样性指标进行了比较分析,结果表明,短周期巨尾桉工业原料人工林林下,共有植物94种,隶属46科,主要以一些阳性和半阳性植物为主,其中菊科和禾本科植物较为普遍。对照样地所反映的原生林林下,共有植物167种,隶属49科。短周期巨尾桉工业原料人工林林下生长的植物在其原生林林下几乎都有分布,但不是优势种。短周期巨尾桉工业原料人工林林下的Simpson指数和Shannon-Weiner指数及均匀度指数3个多样性指数均低于其原生林。短周期巨尾桉工业原料人工林林下各植物物种个体数量分布不均匀,优势物种较突出,而原生林林下各物种株数分布比较均匀,优势物种并不突出。

摘  要：
Choosing 7 sample plots of three years old Eucalyptus grandis × E.urophylla plantation and 7 primary sample plots as study targets,the shrub layer and herbaceous layer were investigated,and the diversity indexes were compared and analyzed as well.The results showed that 94 plant species belonging to 46 families were found under plantation,the dominant species were either sun-loving or middle-light plants,Asteraceae and Gramineae were two families generally existed.In the sample plots of primary forests,totally 167 species belonging to 49 families were found.The results also implied that all the undergrowth species in plantations could be found in primary forests,however,these species were not dominant species.The Simpson index,Shannon-Weiner index and evenness index of plantations were all lower than those of primary forests.In summary,the number distribution of undergrowth plant species of plantations were not even,with outstanding dominant species,whereas the number distribution of undergrowth plant species of primary forests were even and without dominant species.
