| Abstract: | The importance of temperate grassland in northern China in carbon cycle researches of grassland ecosystem was discussed. The characteristics and research status of carbon cycle of temperate grassland in northern China was expatiated at three aspects such as carbon fixation, carbon storage and carbon emission, as well as the main factors affecting these 3 aspects. It emphasized the primary productivity of grassland, soil organic carbon, soil respiration and their responses to the environmental factors and the human activities, and provided reference for the study of carbon cycle of temperate grassland in northern China. |
