| Abstract: | Grassland ecosystems are the main terrestrial ecosystems,and are intensively affected by human activities.Greenhouse gas emissions from grassland ecosystems have severely impacted on the global climate changes.This study gave a brief review of the mechanisms and controlling factors of CO2,CH4 and N2O emissions from grassland ecosystems and indivated that the conjunction of environmental,biological and management factors played a key role in variations of greenhouse gas emissions from grassland ecosystems.Th... |
