Table 1 Single or combined effects of air temperature (AT)/soil temperature (ST) and soil moisture (M) on the seasonal patterns of gross ecosystem photosynthesis (GEP), net ecosystem photosynthesis (NEP), canopy respiration (CR) and soil respiration (SR) under summer grazing (SG) and no grazing (NG) in the meadow steppe (MS), typical steppe (TS) and desert steppe (DS).

  1. The data shown are the R2 of CO2 fluxes induced by the various factors; * and ** indicate significance levels of 0.05 and 0.01, respectively. No significant factors affected NEP; thus, the data are not shown.
