摘　　要：通过样地调查,采用物种丰富度指数(S)、Shannon-Wiener多样性指数(H)、Simpson优势度指数(J)、Pielou均匀度指数(E),分析比较了低效马尾松林试验区群落的物种多样性。结果表明:本区主要植物群落的物种多样性水平整体较低,且各群落的多样性水平相差较小,说明该区各类型群落处于演替的初级阶段。人工引进阔叶树加速了群落的演替,增加了各个层次的物种多样性。在低丘红壤马尾松低效林改造及植被恢复中,应大力引进阔叶树种,以提高林分的物种多样性和保持水土的能力。Based on the field investigation data,the richness index（S）,Shannon-Wiener diversity index（H）,Simpson dominance index（D） and Pielou evenness index（E） were used to study the species diversity of community in the areas of Pinus massoniana deteriorated forests trial place.The results showed that the species diversity of the major plant communities was lower and only a slight differences among them,which implied all of the communities located initial stage of succession.The introduced hardwood species could accelerate the community succession and enhanced the species diversity.Therefore,on reconstructing Pinus massdoniana deteriorated forests and restoring vegetation in the area of red soil low hilly,the hardwood species should be introduced in order to improve species diversity of the forest and soil and water conservation capacity.
