Among different ecosystems,Grassland ecosystem, as one of the main types in terrestrial ecosystems, more rapidly responds to the global climate and environment changes because of its fragile ecology and frequent human activities within it. The release of carbon from grassland to the atmosphere occurs primarily in the form of CO₂ through soil respiration, so soil respiration directly controls the rate of carbon cycle in soil. The authors of this paper introduced the research status of grassland soil respiration at home and abroad, analyzed the factors that influence soil respiration, and proposed some suggestions on soil respiration measurement.
