摘　　要：通过对福建三明格氏栲自然保护区常绿阔叶林9个群丛的物种多样性进行测算,结果表明:保护区内常绿阔叶林物种多样性指数为4.513—2.947;物种均匀度为0.498—0.772;生态优势度为0.049—0.066。并提出了相应的保护建议。Species diversity of evergreen bloadleaved forest in Fujian Sanming Nature Re-serve, was studied by computing of species diversity index, species evenness and ecoloical dominance of associations. The species diversity index ranged from 4. 513 to 2. 947, species evenness from 0. 498 to 0. 772, and ecological dominance from 0. 049 to 0. 066. Some sugges-tions on conservation of Nature Reserve were given.
