Abstract Carbon fluxes and contents are integral components of the global carbon cycle. The photosynthetic and respiratory rates were measured at the levels of leaves and canopies for different community types in a typical steppe ecoregion in Xilin Gol, Inner Mongolia, Northern China. Soil Organic Carbon (SOC) content and density and above-biomass were surveyed in each community type. The results show: 1) thicketized Caragana microphylla and Achnatherum splendens communities exhibit higher above-ground biomass, Maximum Net Photosynthesis Rate (Pnmax), Gross Ecosystem Productivity (GEP), Net Ecosystem Exchange (NEE), and Ecosystem Respiration (ER) (p
