摘要
土壤呼吸在全球碳收支中占据重要地位。LI-8100开路式土壤碳通量测量系统以其精确、快速等优点成为当前土壤碳通量研究的首选仪器之一。本文总结了近些年我国利用该仪器进行土壤碳通量的研究工作,重点阐述了土壤呼吸的日变化、月变化规律,分析了温度、湿度以及土地利用方式等影响土壤呼吸的因素,最后指出了目前利用该仪器进行土壤碳通量研究中存在的主要问题及今后的应用和发展方向。
Soil respiration plays an important role in the global carbon budget. With the advantages of accuracy and rapidity, the LI - 8100 Automated Soil COz Flux System has became the first choice in the study of the soil carbon flux. This paper summarizes the studies of the soil earbon flux in China during the past few decades, especially expounds daily and monthly variation regularity of soil respiration, and analyses the various factors affecting the soil respiration, sueh as temperature, moisture, land use and so on. Finally, the existing problems and future development direction of the applieation of this system was pointed out.
