摘　　要：以太原市汾河公园和森林公园的绿地植物为调查对象,应用群落生态的调查方法,使用丰富度、Shannon-Winner指数、Simpson指数和Pielou指数对2个公园绿地植物的物种多样性特征进行比较分析。结果表明,汾河公园的物种均匀度高于森林公园;2个公园均表现为乔木层物种多样性最高,灌木层次之,草本层最低;整体上森林公园的物种丰富度指数和Shannon指数比汾河公园高,其中,乔、灌、草3层的丰富度均比汾河公园高,尤以草本植物最为丰富。通过比较研究,可为今后太原城市公园绿地的规划与建设管理提供可靠的科学依据。In this study, the plant species diversity in both Fenhe park and Forest park in Taiyuan city were comparatively analyzed using the methods of community investigation and the biodiversity indices（richness, Pielou evenness index, Shannon-Winner index and Simpson index）. The results showed that there was a higher evenness in Fenhe park than in Forest park. The tree layer showed the highest diversity, the shrub layer second and the grass layer the lowest for these two parks. The richness and the diversity of Shannon index of the tree layer, shrub layer and grass layer were higher in Forest park than those for the three layers in Fenhe park. The richness of grass layer in Forest park was especially higher than that in Fenhe park. The comparative research could provide a dependable scientific basis for the planning and construction of Taiyuan urban parks.
