图3. 在13C标记后的30天期间, 冬季轻度放牧(LWG)和围封(Encl)的高寒草甸的植物地上部分、根和植物地上部分呼吸作用下损失的13C动态(平均值±标准误差)。*表示放牧与未放牧样地差异显著(p < 0.05)。
Fig. 3. 13C dynamics in shoots and roots and 13C losses by shoot respiration during a 30 day period following 13C labelling in light winter grazed (LWG) and fence-enclosed (Encl) alpine meadows (mean ± SE). * indicates significant difference between grazed and ungrazed plots (p < 0.05).
