Abstract: The study showed that at low elevation of Three Gorges Reservoir area,Pinus massoniana,Cupressus funebris and Cunninghamia lanceolata were the main coniferous forests,which were respectively divided into 14,9 and 5 community types based on field investigation.The whole trend of their species richness index,species diversity index and species evenness index was that shrub layer and herb layer were larger than tree layer.The diversity indices had no obvious trend along the low elevation gradients,which was probably relevant to the high intensity of human activities in the area.

Key words: Coniferous forests, Species diversity, Low elevation region, Three Gorges area
