摘要:在介绍土壤呼吸测量方法的基础上,介绍了最新LI-8100开路式土壤碳通量测量系统的组成、主要特点、测量原理、典型的测量过程、数据输出等。实验结果表明:LI-8100开路式土壤碳通量测量系统,具有测量精确、自动化程度高、可进行长期的野外测量和可重复的短期测量、测量室内部的扰乱最小化、在周围CO2浓度或接近周围CO2浓度下进行测量等特点,在全球碳循环的研究中必将具有广泛的应用前景。
Based on the soil respiration measurement methods, an introduction was made to the components, main characteristics, measurement principles, a typical measurement process and data output of the LI-8100 Automated Soil CO2 Flux System. The LI-8100 has the flowing characteristics: high measuring precision; automated, continuous, unattended long-term measurements; fast, convenient, repeatable survey measurements; open path soil CO2 flux measurements; designed to minimize perturbations within the chamber during measurements; measurements made at or near ambient CO2 concentrations. The LI-8100 will play an important role in the researches on global carbon cycling.
