摘　　要：通过对拟建厦门至沙县高速公路尤溪段沿线6种典型植被群落的重点调查,依据调查的数据,分析不同群落的物种多样性指数、相似性指数和种-多度分布.结果表明:拟建高速公路两侧的植被群落物种多样性变化较大,植被群落多样性指数相对较低,样方之间物种共有度指数较小,群落乔木层及部分群落林下植被符合对数级数分布.Based upon the investigation of six typical vegetations communities along proposed new Xiamen-Shaxian expressway Youxi part and investigation data,the biodiversity,similarity and species abundance distribution of the vegetation communities were analyzed.Result showed：Species diversity change of the vegetation communities was greater on both sides of the new expressway.The biodiversity and similarity were relatively low.All the arbor layers of the vegetation communities and the undergrowth of some vegetation communities accorded to the logarithmic series distribution.
