A Review of Soil Respiration in Land Surface Model
陆面模式中土壤呼吸的研究概况

Soil respiration is the primary path by which CO2 fixed by land plants returns to the atmosphere.Slight change in soil respiration rate leads to evident change in the concentration of CO2 in the atmosphere and further affects the global climate change.Better representing soil respiration processes including microbial respiration and root respiration processes in land surface schemes could help improve the climate models' simulation to future climate.The soil respiration empirical model and processes-based model are introduced,and the investigations on simulation method of soil respiration processes in land surface schemes are reviewed.In conclusion,the issues that need to improve in soil respiration model are brought forward.
