图9. 土壤呼吸(SR)及其各组分的年际变化(2014-2016)和3年平均值(2014-2016年5-8月份)以及土壤呼吸各组分占总呼吸的比例和菌根呼吸、根呼吸分别占自养呼吸的比例的年际变化和3年平均值(2014-2016年5-8月份)(平均值±标准误差)。SRh、SRa、SRmy、SRr、SRtot分别表示异养呼吸、自养呼吸、菌根呼吸、根呼吸和总呼吸。
Fig. 9. Interannual variations of soil respiration (SR) and its components, the contribution of soil respiration components to total soil respiration and the contribution of SRmy and SRr to SRa during 2014-2016 and averages from May to August of the 3 years (mean ± SE). SRh, SRa, SRmy, SRr and SRtot represent heterotrophic respiration, autotrophic respiration, mycorrhiza respiration, root respiration and total soil respiration, respectively.
