| Abstract: | 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 ... |
| Keywords: | the gas flux of carbon dioxide device in situ measuring soil profile arid area |
