摘　　要：橡胶林生态系统是热带地区重要的人工生态系统,为热带地区的生态服务和经济发展做出了重要贡献,在世界森林生态系统中占有重要的位置。橡胶林土壤呼吸对调控大气CO2有着重要的作用,是全球变化背景下碳循环过程研究的一个重要环节。系统概述了橡胶林土壤呼吸的研究意义、研究方法、影响因素、时空变化以及对干扰的响应和组分区分,指出橡胶林土壤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展望。Rubber plantation ecosystem is an important artificial ecosystem in the tropics, it has made important contributions to the ecological service and economic development in the tropical regions, in the world forest ecosystem plays an important role. Rubber plantation soil respiration plays an important role in regulation atmospheric CO2, it＇s an important research link under the background of the global change of carbon cycle. The paper reviewed research progress on soil respiration in rubber plantation, including research methods, impact factors, spatial-temporal variation, response to disturbing, component division.Pointed out the uncertainly of the study of soil respiration in rubber plantation, and the subsequent research hot spot and direction was prospected.
