图3. 不同底座处理下土壤呼吸速率(SR)与土壤温度(ST)之间的关系。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. 3. Relationship between soil respiration rate (SR) and soil temperature (ST) at 10 cm soil depth 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.
