中文摘要：
土壤呼吸是陆地植被吸收的CO2返回大气的基本途径，土壤呼吸速度轻微变化也会引起大气中CO2浓度的明显改变，进而影响气候变化。陆面过程模式中更好地描述土壤呼吸过程对于预测未来气候变化是至关重要的。对于土壤呼吸的模拟研究，介绍了经验模型和以过程为基础的机理模型，以及国内外陆面过程模式中土壤呼吸的研究情况，并讨论了土壤呼吸模式中需要改进的问题。
英文摘要：
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.
