采用丰富度（R1、R2）、多样性（D、H）和均匀度（J1、J2）各2种指数研究龙王山落叶阔叶林的物种多样性。结果表明，龙王山落叶阔叶林植物资源丰富，灌木种数最多，草本植物最少，共计有维管束植物54科91属140种（含变种）；群落层次分明，从上到下，分为乔木层、灌木层和草本层，并有少量层间植物。乔木层和草本层中优势种比较明显，灌木层中各优势种的差异不明显；丰富度指数（R1、R2），多样性指数（D、H），均匀度指数（J1、J2）的变化趋势均一致，灌木层＞乔木层＞草本层；t检验结果表明，各个层次之间的物种丰富度和多样性差异性均显著，灌木层的均匀度指数（J1、J2）与乔木层和草本层的差异性并不显著，而乔木层与草本层均匀度差异却相对显著。

Species diversity of plant communities in Longwang Mountain was studied by using seperately 2 in-dex of richness index (R1 ,R2 ),diversity indices (D,H)and evenness index(J1 ,J2 ).The results showed that the deciduous broad-leaved forest in this area had rich plant species.Among them,the number of shrub species were the most and the herb were the least.It totaled 54 families,91genera and 140 species (including variations) of vascular plant species.The vertical structure of community was relatively beautifully layered which could be di-vided into tree layer,shrub layer,herb layer,and a definite number of interstratum plants besides.The dominant species in tree and herb layer were quite obvious,but the dominant species in the shrub layer of the differences was the opposite.The change trend of richness index(R1 and R2 )、diversity index(D and H)and evenness index (J1 and J2 )were the same (shrub layer>tree layer>herb layer).T-test results showed that the differences of the spe-cies richness and diversity between all layers were significantly.The evenness index between the shrub layer and the other layers has no significant difference,while the evenness index of the tree and shrub layer were relatively significant.
