Abstract:: Yuanyang terrace with over 1 200 years of history, the existence of water-holding forest has an important value for development of Yuanyang terrace. In order to investigate the distribution of plant diversity in water-holding forest of Yuanyang terrace, this study adopted the method of standard statistical and on-site investigation. The study on the quantitative features, the species richness, diversity and evenness, etc. characteristics in 4 types of vegetation regions in Quanfu middle village basin were carried out. The results showed that there were 155 species of plants in this area, belonging to 66 families, and Theaceae, Poaceae and Polygonaceae were 3 dominant families. The different vegetation regions had different dominant species. The species richness index followed the order of secondary evergreen broad-leaved forest > weed tree forest > secondary deciduous broad-leaved forest > artificial Alder forest. Within tree layer, the diversity indices followed the order of secondary evergreen broad-leaved forest > secondary deciduous broad-leaved forest > weed tree forest > artificial Alder forest. Within shrub layer the diversity indices followed the order of secondary evergreen broad-leaved forest > weed tree forest > secondary deciduous broad-leaved forest, there was no shrub layer in artificial Alder forest. Within herb layer, the diversity indices followed the order of secondary deciduous broad-leaved forest > artificial Alder forest > secondary evergreen broad-leaved forest > weed tree forest. The species richness and evenness of vegetation distribution had across-impact on species diversity.
