Fig. 6From: Effects of simulated acid rain on soil respiration and its component in a mixed coniferous-broadleaved forest of the three gorges reservoir area in Southwest ChinaRelationship between the mean soil respiration rate in October 2017 and soil properties. R represents the soil CO2 fluxes (μmol∙m− 2·s− 1) in the untrenched plots and trenched plots. The graphs without trend lines represent nonsignificant linear relationshipsBack to article page
