Environment factor codes are as follows: elevation, altitude of plot; SWC, soil water content; TN, soil total nitrogen content; AN, soil ammonium nitrogen content; NN, soil nitrate nitrogen content; RAP, soil rapid available phosphorus content; pH, soil pH value; slope, slope of plot; WCD, woody species coverage degree. Phylogeny and trait codes are as follows: MNTD, mean nearest phylogenetic taxon distance; LA, leaf area; SLA, specific leaf area; LDMC, leaf dry matter content; H max, maximum plant height; LNC, leaf nitrogen content; LCC, leaf carbon content; C:N, carbon–nitrogen ratio of leaves; SM, seed mass.
The environment factor has the second best explanatory power for this trait/phylogeny.
