| 英文摘要 | Legacy effects are the ecological inheritances produced by preceding actions, which have been underlined more on agricultural land use, wildfire, invasive and removal species, forest management, and extreme climates in previous research; however, very few studies have shown concern toward the grazing legacy effects on key ecosystem functions such as the carbon cycle. A nested random block design was employed in 2012, with historical grazing as the block factor and precipitation as a nested factor, to explore the regulatory mechanisms on the carbon fluxes in a desert steppe. This long-term grazing practice had exerted unique legacy effects on community composition through increasing the proportion of Stipa breviflora Griseb. (P-stipa) by 61.53%, and decreasing species richness (R-sp) by 30.70%, cover by 21.87%, aboveground biomass (AGB) by 31.34%, and carbon allocation (the ratio of ANPP/BNPP) by 15.18%. Moreover, plants had differential adaptations to herbivores. Remarkably, these grazing legacies indirectly promoted plant photosynthesis (GEE) and carbon gain (NEE). Precipitation, as expected, accounted for the variability of GEE by 43% and NEE by 33%. The results revealed that precipitation controlled the magnitude of carbon fluxes while grazing legacies offset the adverse effects of current grazing and, therefore, mediated carbon sequestration.
