- Abstract:
-
The plant leaf water-holding functional groups were classified by using principal component analysis and hierarchical cluster analysis from the point of plant modality structure-function-plant functional groups.The results showed that there were four factors which determined the function of water-holding capacity, leaf size, leaf L/W and leaf water holdup, leaf angle, then 23 species were classified into five plant functional groups based on the appraisement of water-holding capacity of the species in Caohai water functional district.The five plant functional groups were as followings: broad-leaved leaves with high water retention function group, broad-leaved with middle-level water retention function group; broad-leaved lobule with ordinary water-holding function group; the needle with middle-level water holding function group and smaller broad-leaved with low water holding function group. At the meantime,the basic features of the five PFGs were revealed, which could provide a theoretical basis for creating the conservation forest and ecological restoration in the process of species selction, structural optimization.
