Fig. 5. Radar plots of trade-offs among multi-ecosystem services (functions)(A) and Radar plots of the ES values (B) of multi-ecosystem services (functions) for the studied grassland under grazing gradients. CK, control; LG, light grazing; MG, moderate grazing; HG, heavy grazing. GER, grassland evapotranspiration rate; GP, grassland net growth production; NPR, community net photosynthetic rate; SOC, soil organic carbon; SRR, soil respiration rate; SWC, soil water content; SWI, Shannon-Wiener index.
