| 摘 要： | 土壤是温室气体(CO2、CH4和N2O)的重要排放源,对全球气候变化起着至关重要的作用,因此对土壤温室气体准确测量具有巨大的现实意义。箱法和涡度相关法是测量土壤温室气体的主要方法。参考国内外文献资料,概述了静态箱法、动态箱法和涡度相关法的原理和优缺点,并在此基础上对不同测定方法进行了比较。最后指出了多种土壤温室气体的同步、原位监测将是未来土壤温室气体监测的发展趋势。

| Abstract: | Soil is an important emission source of greenhouse gases(CO2,CH4 and N2O),and plays an important role in global climate change.Therefore,accurate measuring soil greenhouse gas has great significance.Chamber method and eddy covariance method are the main methods for measuring soil greenhouse gas.According to domestic and foreign literature,the principles,the advantages and disadvantages of the static chamber method,the dynamic chamber method and the eddy covariance method were reviewed,and then a comparison was conducted among these methods.Finally,the future development trend of measurement methods for soil greenhouse gas was prospected. |
