【摘要】 俄罗斯平原针-阔林过渡带森林群落的物种多样性的研究表明，该地区的物种多样性类同于许多类型的过渡带，即群落的过渡带（针阔混交林）比相邻群落（针叶林和阔叶林）具有更高的多样性。针阔混交林群落的组成结构较好地反映了其特殊的过渡性。在该过渡带较高的物种多样性并不证明群落稳定性的增加。因此，在探讨多样性与群落稳定性关系时，综合包括均匀度在内的多个指数才可能作出较为客观的结论。更多还原

【Abstract】 This paper studied on species diversity in ecotone of coniferius and broad-leaved forest communityin Russia Plain. The results show that species diversity in this region is similar to those in most other ecotones.The species diversity in the ecotone (mixed coniferous and broad-leaved forest) is higher than those in contiguous communities (coniferous and broad-leaved forest). The composition structure of mixed coniferous andbroad-leaved forest communities represents its special transition feature. In this ecotone,the higher diversitycan’t demonstrate the increasing of the community stability. Therefore, the correct results rely on the integrated consideration of more indexes when the relationship between species diversity and community stability isdiscussed.更多还原
