Effects of climate change on soil organic carbon storage of grassland ecosystem
Grassland soil organic carbon pool becomes a focus in the field of grassland ecosystem in recent years due to the advance in the global climate change and transfer of carbon of the terrestrial ecosystems in various ways.Grassland soil organic carbon is an important component of the global carbon cycle,directly affecting on the global carbon balance.The impact of human-induced climate warming resulting from the increase of greenhouse gases on grassland ecosystems arouses the considerable attention.Temperature,precipitation,atmospheric CO2 concentration,and other climatic factors greatly influence on the grassland soil organic carbon pool.Understanding the effects of climate change on the grassland soil organic carbon pool is critical for predicting the changes in grassland ecosystem carbon cycling in the future.This study summarized the advance in the distribution of organic carbon storage in the grassland soils and the effects of temperature,precipitation change,and elevated atmospheric CO2 concentration on grassland soil organic carbon storage,and then proposed the problems,direction and key field of grassland soil organic carbon in the future.
