Abstract: A vast amount of material and literature of the horizontal and vertical distribution of dominants, main companions of subtropical evergreen broad-leaved forest in China waere collected. 112 dominants and main companions, including 14 families, were selected to study the relationships between the climate and the vegetation. Those families were Myricaceae, Juglandaceae, Fagaceae, Magnoliaceae, Lauraceae, Theaceae, Hamamelidaceae, Daphniphyllaceae, Elaeocarpaceae, Araliaceae, Styracaceae, Aquifoliaceae, Frieaceae and Symplocaceae, respectively. Kira’s warmth index (W I ), Coldness index (C I ) and Xu’s humidity index (H I ) of those 112 kinds of dominants and main companions were calculated. The groups of Kira’s water-temperature distribution of main species of subtropical evergreen broad-leaved forest in China were classified into five types.Penman’s potential evapotranspiration (PET) and aridity (A) of the dominants and main companions were calculated. The groups of Penman’s water-temperature distribution of main species of subtropical evergreen broad-leaved forest in China were classified into five types, too.Thornthwaite’s potential evapotranspiration (APE), humidity index ( I H), aridity index ( I A) and moisture index ( I M) of those 112 kinds of dominants and main companions of subtropical evergreen broad-leaved forest in China were calculated. The groups of Thornthwaite’s water-temperature distribution of the dominants and main companions were classified into five types.Holdridge’s biotemperature (BT), potential evapotranspitation (P E), precipitation (P) and potential evapotranspiration ratio (PER) of the dominants and main companions were calculated. Holdridge’s water-temperature distributional groups of main species of evergreen broad-leaved forest in China were classified into five types too.
