对乌拉苔草湿地生长季节内土壤CO2和CO的变化特征进行了模拟研究。结果表明:生长季节的乌拉苔草湿地土壤释放CO2,并消耗CO。化学反应CO+H2O→CO2+H2对于CO2和CO的动态变化起主要作用,CO2和CO之间存在显著的负相关。温度对CO2和CO体积分数的影响存在一定差异,但差异不显著。 The variation characteristics of soil CO2 and CO in the growing season of Carex aequalis were simulated. The results showed that in the growing season, the soil of Carex matsudana released CO2 and consumed CO. Chemical reaction of CO + H2O → CO2 + H2 plays a major role in the dynamic changes of CO2 and CO, there is a significant negative correlation between CO2 and CO. The effects of temperature on CO2 and CO volume fraction were different, but the differences were not significant.
