Abstract:Livestock grazing can strongly determine how grasslands function and
their role in carbon cycle. However, how ecosystem carbon exchange
responds to grazing and the underlying mechanisms remain unclear. We
measured ecosystem carbon fluxes to explore the changes in carbon
exchange and their driving mechanisms in a 16-year long term experiment
with different grazing intensities in a desert steppe grassland. We
found that grazing intensity influenced above- and belowground biomass
during the peak growing season, p… Show more
