摘　　要：基于阿伏加德罗定律和理想气体状态方程原理,设计了一种测量同化箱实际体积和二氧化碳通量的闭路测定方法,并对零碳通量、净光合以及净呼吸的样品进行通量测定验证。结果显示,改进的装置和方法能够在不改变受测对象生理生态特征的前提下,快速、精确地计算同化箱系统的有效作用体积,提高植物光合、动植物呼吸以及微生物分解等碳通量相关研究的科学性。Based on Avogadro’s law and the ideal gas law,a closed-circuit method was designed to measure the actual volume and CO2flux of the assimilator chamber.Samples of zero flux,net photosynthesis and net respiration were tested in this study.The improved device and method can quickly and accurately calculate the effective volume of the assimilation chamber system without changing the physiological and ecological characteristics of samples,and improve the reliability of carbon flux-related research such as plant photosynthesis,biological respiration and microbial decomposition.
