图5. 不同底座处理下土壤呼吸速率(SR)与底座内地上净初级生产力(post-ANPP)之间的相关关系。D2S15表示不锈钢方形底座入土深度为2 cm, 边长15 cm, D5S15表示深度为5 cm, 边长15 cm, D2S30表示深度为2 cm, 边长30 cm, D5S30表示深度为5 cm, 边长30 cm。
Fig. 5. Relationships between soil respiration rate (SR) and aboveground net primary productively (post-ANPP) under different treatments. D and S denote the buried depth and length of the square soil collar, respectively. D2S15, D = 2 cm and S =15 cm; D5S15, D = 5 cm, S = 15 cm; D2S30, D = 2 cm, S = 30 cm; and D5S30, D = 5 cm, S = 30 cm.
