气候变暖时土壤呼吸研究需要加强关注的重要过程 A:新鲜有机碳的输入 Fresh carbon input; B:激发效应 Priming effect; C:微生物代谢产物与土壤矿物表面相结合形成稳定的有机质 Microbial products bound to soil-mineral surface to form stable organic matter; D:土壤动物取食植物地上部 Plant shoot consumed by soil animals; E:土壤动物取食植物根系 Plant root consumed by soil animals; F:土壤动物影响根系生物量和分泌物量 Soil animals affect root biomass and excretion; G:土壤动物通过植物根系调控根际微生物 Soil animals regulate rhizospheric microorganism via plant root; H:土壤动物改变土壤有机质存在形态 Soil animals change the status of soil organic matter; I:土壤动物改变土壤微生物活性和群落组成 Soil animals change the activity and composition of soil microbes; J:微生物的分解作用Microbial decomposition; K:土壤动物活动加速凋落物分解 Soil animals accelerate litter decomposition; L:土壤冻融循环导致植物根系死亡Soil freezing-thawing processes lead to the death of plant root; M:植物根系死亡增加呼吸底物 The death of plant root increases the respiratory substrate; N:土壤冻融过程改变土壤有机质可利用性 Soil freezing-thawing processes change the availability of soil organic matter; O:土壤冻融循环改变微生物活性和群落结构 Soil freezing-thawing processes change the activity and composition of soil microbes.
