摘要：The prent study compares the vegetation characteristics of two large forested and one large n
on-forested solution dolines in Hungary. We investigated the species composition and vegetation pattern along north to south trancts (across the doline bottoms) and compared the richness of different species groups (dry and wet groups) on the doline slopes. We applied linear regression models for each slope to explore the effects of topography on species richness, and Detrended Correspondence Analysis (DCA) to detect the major gradients of floristic variation within each site. We found that the vegetation changed significantly along all trancts; and, regardless of the vegetation cover, the doline bottoms contained veral cool-adapted species. Variations within the two species groups were more pronounced on the south-facing slopes.
