Data for "Ecotone drives spatial heterogeneity of soil functional diversities"

Ecotones form by high-altitude mountainous have larger environmental gradients and complex landscape elements. However, there is limited understanding of the biogeography of soil microbiome functions and their multiscale coupling with biotic and abiotic factors in ecotones. Here, we analyzed soil metagenomes, plant communities, and environmental factors across the elevation and slope aspects in the Qinling Mountains, the largest terrestrial ecotone in China.
