图5. 在春季气温上升的3种情境下(+1、+2、+3 ℃)所研究生态系统返青期的变化。负值为返青期延后, 正值为返青期提前。A, 升温1、2和3 ℃情况下所有研究点返青期变化量的频数。B、C、D分别为升温1、2 和3 ℃时各个生态系统返青期变化量的频数。
Fig. 5. Predicted changes of green-up date under the three scenarios of elevated spring-temperature at 1, 2 and 3 °C for the target areas. Negative and positive dates indicate the delayed and advanced days of the green-up date, respectively. A, Predicted changes under all the three temperature scenarios. B, C, D, Predicted changes for each target area with the temperature increase of 1, 2 and 3 °C, respectively.
