Dissolved organic matter (DOM) plays a key role in many biogeochemical processes, but the drivers controlling diversity of chemical composition and properties DOM molecules (chemodiversity) soils are poorly understood. It has also been debated whether environmental conditions or intrinsic molecular control accumulation persistence due to complexity both interactions between surrounding environments. In this study, soil samples were extracted from 33 collected different regions China, we investigated effects climate on chemodiversity across employing combination Fourier transform ion cyclotron resonance mass spectrometry, optical spectroscopy, statistical analyses. Our results indicated that, despite heterogeneity complex influencing factors, aridity clay can account for majority variations composition. The finding implied that is an ecosystem property closely related environment, be used developing large-scale biogeochemistry models predicting C cycling soils.
