摘要
土壤是大气痕量气体的重要源和汇之一。人类通过改变土地利用方式,大量施用化肥等活动正在改变着土壤作为温室气体源和汇的强度。由于人类对自身健康和生存环境变化的关切,痕量气体研究有可能突破温室气体和温室效应的范畴,而成为依赖于技术的进步而发展的又一门新兴的学科。土壤痕量气体研究在这一新兴学科中占有相当重要的位置。
Soil serves as one of the most important sources and sinks of trace gases. However, as a source and a sink as well, soil is being changed because of human activities, such as changing land use and applying fertilizers. Being concerned about human health and global change, research on trace gases will not be limitel in greenhouse gases and their greenhouse effect. A new scientific branch may be developed with the improvement of analytical techniques. Of the new branch, research on soil trace gases will play an important part.
