图5. 西安39种木本植物展叶始期的积温模型模拟效果。A, 模型的拟合优度(R2)和均方根误差(RMSE)。B, 各物种在异常气候年和正常年的模拟误差。实心柱代表异常气候年的误差显著不为0 (p < 0.05)。物种编号同表1

Fig. 5. Effect of growing degree day model for simulating the first leaf date (FLD) of 39 woody species in Xi?an. A, Goodness of fit (R2) and root mean square error (RMSE) of the models. B, Error of the model in simulating the FLD in the years with abnormal and normal climate. The solid bars represent that the mean error was significant from 0 (p < 0.05). See Table 1 for species No.
