The holistic distribution characteristics of 4 species groups: evergreen vs. deciduous and tree vs. shrub species along the altitudinal gradient were then analyzed.
The diurnal range of temperature indicated a U-shaped pattern along the altitudinal gradient, with a lowest value at the middle elevations (about 1600 m).
The fitted curve of both diversity and richness of herb layer with DCCA axis 1 was more significant than that fitted with altitudinal gradient, while that of shrub layer showed the opposite trend.
