摘要
采用群落学调查方法,对云南省澜沧县9年生巨尾桉林下植物多样性进行研究。结果表明,巨尾桉林下共有维管束植物78科、201属、293种及变种,其中蕨类植物5种,种子植物288种。种子植物以菊科、蝶形花科、禾本科、茜草科、蔷薇科为主要优势种。物种丰富度的变化规律是草本层>灌木层,Simpson指数和Shannon-wiener指数的变化规律是灌木层>草本层。
Using community investigation method,the undergrowth vegetation diversity of 9 years old Eucalyptus grandis forest in yunnan region has been studied. Results show that the Eucalyptus grand forest has 78 families of vascular plants,which belonged to 201 genera,293 species and varieties,including 5kinds of fern,288 species of seed plants. Seed plants mainly dominated by Leguminosae,Gramineae,Rubiaceae and Rosaceae family. Species richness change law follows as herb layer shrub layer,Simpson index and Shannon- wiener index as shrub layer〉 herb layer.
