Analysis on understory vegetation diversity of Eucalyptus sprout forest in Qibo Forestry of Guangxi
摘要
Abstract
This paper aimed to study the understory vegetation diversity of Eucalyptus sprout forest in Qi-bo Forestry of Guangxi in order to provide basis for creating moderately developed undergrowth vegetation environment and improving Eucalyptus plantation's sustainable management. [Method] In this study done by the Guangxi State Qibo Forestry, the diversity characteristics of vegetation species in the second generation of Eucalyptus artificial sprout forest were investigated, and the richness, Simpson, Shannon-Winner, and Pielou evenness index were quantitatively calculated and analyzed to identify the dominant undergrowth vegetation species. [Result]The species diversity, Simpson, Shannon-Winner, and Pielou index of understory vegetation in shrub layer of Eucalyptus sprout forest were higher than those of herb layer species; their richness was 33 and 11 in the 1" sampling plot, and 27 and 8 in the 2? sampling plot respectively. [Conclusion]The Euralyptus sprout forest in Qibo Forestry of Guangxi has rare understory vegetation, lower species' richness , and diverse get even Pielou index; their effects on the diversity of undergrowth vegetation in the herb layer were higher than the shrub layer.关键词
