中国科学院地理科学与资源研究所牛书丽课题组在Nature Reviews Earth & Environment 上发表关于生态系统呼吸温度响应的综述(图)
牛书丽 生态系统 呼吸 群落
2024/8/8
生态系统呼吸(ER)是生物圈与大气之间最大的碳通量之一,研究ER的温度响应是准确预测未来大气CO2浓度以及气候变化的关键。目前陆面模型普遍认为ER随温度升高持续增加,甚至预测在本世纪末陆地生态系统呼吸所排放的CO2通量将超过光合作用吸收的CO2,从而使陆地生物圈从全球碳汇(净吸收)变成碳源(净排放)。然而近期的观测研究发现ER广泛存在最适温,即ER的温度响应是单峰型而非传统认知上的指数型,当温度超...
