摘要
设计和研制了一套土壤剖面CO2气体通量原位测试的方法和装置,该方法和装置可用于土壤剖面不同深度（0～200 cm）土壤CO2气体通量的观测、不同深度土壤层CO2气体存储量的估测、土地利用/土地覆盖变化引起土壤CO2气体释放量变化的测算和估计,以及植被或地力恢复速率的评价等。
A device was designed and a new method for in situ measuring carbon dioxide flux at various depths of arid soil was developed. The measuring principle of the device was discussed and the working procedures were introduced. The method was used in the determination of CO2 concentration and flux at soil. The results indicated that the method and device could be applied in the observation of soil CO2 flux at depths within 200 cm, prediction of the CO2 storage at different soil depth, and estimation of the change of CO2 emission caused by change of land-use/land-cover, as well as the assessment of restoration rate of vegetation or soil fertility, etc.
