乌拉苔草湿地土壤CO_2和CO的变化特征

Changing Feature of Carbon Dioxide and Carbon Monoxide in Carex meyeriana Wetland Soil

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。

An experiment was conducted to simulate the changing feature of CO2 and CO in Carex meyeriana wetland soil during growing season. Results showed that soil produces carbon dioxide and consumes carbon monoxide in Carex meyeriana wetland during growing season. The chemical reaction, CO ＋ H2O→CO2 ＋ H2, plays an important role in the dynamic change of carbon dioxide and carbon monoxide. Carbon dioxide has a significantly negative correlation with carbon monoxide. Effect of temperature on carbon dioxide and carbon monoxide has an insignificant difference.
