Using community ecology techniques and quantitative measurements of elevation results show a linear relationship between elevation and plant functional groups (PFGs) of composition species, which were significantly correlated (P<0.05, or P<0.01) in the differential ecosystem types along differential elevation gradient on the southern side of the Fu-Niu Mountain. The results indicated that elevation is the most important environmental factor affecting the distribution pattern of the dominant/companion species at PFGs levels along elevation gradient. PFGs of composition species of importance values were significantly correlated with elevation (P<0.05, or P<0.01) on the southern side of the Fu-Niu Mountain. Therefore, this study plays a vital part in conserving global plant functional groups diversity and maintaining global ecosystem function.
