摘要：

全球变化背景下陆地植物的源汇效应一直是陆地生态系统研究的热点之一.暗呼吸在碳循环中占有重要的位置,是全球变化背景下碳循环过程研究的一个重要环节.目前国内外有关植物暗呼吸方面的研究还较少.本文就植物暗呼吸作用的生理过程、暗呼吸的观测方法,以及植物自身生物因素和环境因子对暗呼吸的影响进行了介绍,指出植物暗呼吸研究中存在的不确定性,并对后续研究的热点与方向进行了展望.

Abstract: The source and sink effect of terrestrial plants is one of the hotspots in terrestrial ecosystem research under the background of global change. Dark respiration of terrestrial plants accounts for a large fraction of total net carbon balance, playing an important role in the research of carbon cycle under global climate change. However, there is little study on plant dark respiration. This paper summarized the physiological processes of plant dark respiration, measurement methods of the dark respiration, and the effects of plant biology and environmental factors on the dark respiration. The uncertainty of the dark respiration estimation was analyzed, and the future hotspots of related researches were pointed out.
