| 中文摘要: |
| 陆地生态系统土壤呼吸是全球碳循环的重要过程之一，陆地土壤碳库的微小变化将直接影
响全球碳平衡，并对大气CO2 浓度造成大的扰动。森林、草地及农田三大生态系统土壤碳库作为陆地生
态系统土壤碳库的重要组成部分，是决定未来土壤碳源、汇动态的关键部分。综述了不同土地利用方式
的土壤呼吸测定方法及土壤呼吸动态，并结合目前不同空间尺度及生态系统土壤呼吸的研究现状，提出
未来研究中应加强不同测定方法所得结果间的比较，以及复杂环境条件下土壤呼吸模型的研究与尺度扩
展应用。 |
| 英文摘要: |
| The land ecosystem soil respiration is one of the important process of the global carbon cycle，small
changes in terrestrial carbon pools will directly influence the global carbon balance，and cause large disturbance to
the atmospheric CO2 concentration. Forest，grassland and farmland ecosystem of carbon pool is a key part of deciding
on the dynamics of soil carbon source and sinks as an important component of the terrestrial ecosystem soil carbon
pool. In this paper，we reviewed method for determination of soil respiration under different land-use types，dynamics
of soil respiration under main mode of land use in our country in recent years，and proposed that strengthening the
comparison among results from different testing methods and soil respiration model research and scaling application
under the condition of complex environment were the direction and focus for further research based on research status
of different spatial scales and ecosystem soil respiration. |
