Mantel’s results of soil nutrients on the stoichiometry traits of plants in the Ligularia virgaurea spread community. N: plant nitrogen content and C: N in aboveground biomass and roots; P: plant phosphorus content and C: P in aboveground biomass and roots; C: plant carbon content in aboveground biomass and roots; NP: plant N: P in aboveground biomass and roots; TN: soil total nitrogen; NH4+-N: soil ammonium nitrogen; NO3--N: soil nitrate nitrogen; TP: soil total phosphorus; AP: soil available phosphorus; TOC: soil total organic carbon; MBC: microbial biomass carbon; MBP: microbial biomass phosphorus; MBN: microbial biomass nitrogen.
