利用动态箱法研究了ＣＯＳ在麦田土壤中的地气交换，结果表明麦田土壤为ＣＯＳ的重要汇．Ｃ０Ｓ在麦田土壤中的沉降速率随ＣＯＳ的浓度增加而增大，与温度密切相关，在１５～２０℃范围内和实际大气情况下，ＣＯＳ在麦田土壤中的沉降速率达到最大值约为 ０．６ × １０～－１２ ｍｏｌ·ｇ－１·ｈ－１．实验测量 ＣＯＳ在麦田土壤表面的沉降速率与温度的关系与Ｇｕｅｎｔｈｅｒ简化算式计算结果十分吻合．
The dynamic box method was used to study the gas exchange in the soil of wheat fields. The results showed that the soil of the wheat fields was an important sink for COS. The sedimentation rate of C0S in wheat field soil increased with the increase of COS concentration, which was closely related to the temperature. The maximum sedimentation rate of COS in wheat field soil reached about 0 at 15 ~ 20 ℃ and in real atmosphere. 6 × 10 ~ -12 mol · g-1 · h-1. The experimental measurement of COS on the soil surface sedimentation rate and temperature relationship with Guenther simplified calculation results are in good agreement.
