摘要
本文探讨了森林生态系统中植物─土壤─大气ＣＯ＿２气体交换测定装置。本装置在草原生态系统植物群落光合作用测定装置基础上改进而来，适用于森林地带无交流电源，交通运输不便的地区，利用便携式ＣＯ＿２红外线分析仪和粉尘采样器替代气泵，具有经济、经便，实用等特点。
The design and improvement of the device for measuring CO_2exhausted fronl the soil-plant system of the forest ecosystem were discussedin this paper.The device was developed from that popularly used in the grassland ecosystem study,which is suitable better for tlie forest areas wherethere are no electronic power and the transportation is mostly difficult.Theportable home-made infrarcd CO_s-gas analyzer and the dust-collection devicewere used for thc improvement.
