摘要：
The exchange of COS between wheat soil and atmosphere was investigated by using a dynamic enclosure. The investigated soil type acted as a significant sink for the trace gas COS. Atmospheric COS mixing ratios and temperature were found to be the physicochemical parameters controlling the uptake. The uptake reached maximum about 0.6×10mol ?g?hat 15-20℃ under natural ambient atmospheric conditions. The measured uptake values agree well with that calculated by Guenther algorithm.
