摘　　要：【目的】毛竹林下层植被在林地生态系统中具有重要的作用,为探究过度开发毛竹林地下层植被恢复对林地植物多样性变化的影响,探索毛竹纯林植被多样性恢复模式。【方法】在安吉县选择过度开发毛竹林地种植杨桐和大苞萱草,经过多年的自然生长后,开展林地植被调查,并进行多样性和稳定性分析。【结果】植被恢复促进了毛竹林物种种类的增加,多样性指数也显著高于毛竹纯林;植被恢复在一定上提高了过度开发毛竹林地的群落稳定性,并促使其向着相似的复杂群落演替,但由于大部分植被仍然比较脆弱,群落结构尚处于不稳定状态。【结论】要使过度开发的毛竹林地恢复到稳定的毛竹群落结构,须进行长期的林下植被恢复和人工抚育干预。【Objective】The understory vegetation plays an important role in Phyllostachys pubescens forest ecosystem.In order to explore the effects of underground vegetation on the changes of plant diversi⁃ty in overexploitation Phyllostachys pubescens forest,and to recommend a good pattern of vegetation diver⁃sity restoration for pure Phyllostachys pubescens forest.【Methods】Adinandra millettii and Hemerocallis middendorfii Trautv.et Mey.were planted under overexploitation Phyllostachys pubescens forest in Anji county.After years of natural growth,forest vegetation investigation was carried out and diversity and sta⁃bility were analyzed.【Results】The results showed that vegetation restoration promoted the increase of species,and diversity index of vegetation restoration forest was significantly higher than that of pure Phyl⁃lostachys pubescens forest.Vegetation restoration had improved the stability of overexploitation Phyllo⁃stachys pubescens forest to a certain extent,and promoted its succession to similar complex communities.However,because most of the underground vegetation was still fragile,the community structures of the three Phyllostachys pubescens forests were still in an unstable state.【Conclusion】In order to restore the damaged system of Phyllostachys pubescens forest to a stable community structure,long-term under⁃ground vegetation restoration and artificial tending must be carried out.
