摘 要(英文):Based on the investigation along the transect of 10 m ×1 200 m in the Dinghu Moutain ,which started from 50. 2 m to 476. 5 m above sea level ,the vertical pattern of plant community and their biodiversity were studied. There were 3 forest types and 5 communities along the transect ,which consisted of a succession series.But vertical distribution was not in order. In the tree layer ,the biodiversity index was in order of broad-leaved forest of mesophytes > pine and broad-leaved mixed forest > broad-leaved forest of heliophytes ; In the herblayer ,The biodivecsiey index was in order of pine and broad2leaved mixed forest > broad-leaved forest . Most herb groups of heliophytes grew in pine and broad-leaved mixed forest and broad2leaved forest of heliophytes. The distribution of herb groups was complex under tree canopy , and some herb groups of shade-tolerance species grew under heliophytes groups ,which indicated that micro2environment under tree-crown could influence the pattern of herb group distribution obviously.
