Abstract: To understand the impacts of climate change on the soil organic carbon storage in terrestrial ecosystems is of significance in predicting the changes of soil organic carbon in the future,and the interactions between terrestrial ecosystems and climate change.We presented the approaches of soil profile measurement,soil organic carbon modeling,and others to estimate the soil organic carbon storage in terrestrial ecosystems,and the uncertainty of these estimations.The research progress in understanding the effects of climate change on soil organic carbon storage in terrestrial ecosystems and the modeling of corresponding processes were reviewed,and the estimations of soil organic carbon storage changes under future climate changes were pointed out,with some questions in the estimations put forward.

Key words: Ecosystem, Flux, Micrometeorological method, Chamber method
