图6. 在3种春季降水增加的情景下(+10、+20、+30 mm)所研究生态系统返青期的变化情况。负值表示返青期延后, 正值表示返青期提前。A, 增水10、20和30 mm情况下所有研究点返青期变化量的频数。B、C、D分别为增水10、20和30 mm时各个生态系统返青期变化量的频数。
Fig. 6. Predicted changes of green-up date under the three scenarios of elevated spring-precipitation at 10, 20 and 30 mm among each target area. Negative and positive dates indicate the delayed and advanced days of the green-up date, respectively. A, Predicted changes for all the three precipitation scenarios. B, C, D, Predicted changes for each target area with the precipitation increase at 10, 20 and 30 mm, respectively.
