We studied the carbon allocation of deciduous trees infected with microbes in soils and greenhouse gas (CO_2 and CH_4) emission rates under a free air CO_2 enrichment (FACE) as affected by soil fertility and simulated tropospheric ozone (O_3). Root growth and microbes' infection of birch were clearly inhibited by O_3 with an open top chamber method. Although plant defense was enhanced by elevated CO_2 but slightly reduced with high soil fertility. At high CO_2, rate of CO_2 efflux increased and CH_4 absorption rate was reduced. Moreover, number of species of collembolan with high mobility was tended to be abundant at high CO_2 treatment with thick litterfall accumulation.

我们研究了受土壤肥力和模拟对流层臭氧(O_3)影响的自由空气CO_2富集(FACE)下受土壤微生物感染的落叶树的碳分配和温室气体(CO_2和CH_4)排放率。开顶室法中O_3对桦树根系生长和微生物侵染有明显的抑制作用。虽然CO_2升高会增强植物防御能力，但土壤肥力较高时，植物防御能力略有减弱。高CO_2条件下,CO_2流出率增加,CH_4吸收率降低。此外，在高CO_2处理下，高迁移率的跳虫物种数量趋于丰富，且凋落物积累较多。
