Data associated with manuscript

Four databases are included in this file:
File nematode tree was used to calculate nematode phylogenetic diversity.
File nematode traits includes nematode functional traits, such as C-P value, Biomass, and Trophic Structure, to calculate nematode functional diversity.
File nematode composition includes soil nematode community
File environment factors includes soil factors and climate factors to explore the driving mechanisms of nematode diversity.
