图9. 老白山低(L)(A)、中(M)(B)、高(H)(C)海拔云杉年轮蓝光强度(BI)和年轮宽度指数(RWI)与当年夏季标准化降水蒸散指数(SPEI)的滑动相关及滑动相关系数的标准差。虚线表示95%置信水平; r, 滑动相关系数; **, 在0.01的水平上显著相关。
Fig. 9. Moving correlation analysis between the standard chronologies of blue intensity (BI) and ring width index (RWI) in Picea jezoensis and summer Standardized Precipitation Evapotranspiration Index (SPEI) at low (L)(A), middle (M)(B) and high (H)(C) elevations in Laobai Mountain and the standard deviations of the moving correlation coefficients. Dotted line represents 95% confidence level; r, moving correlation coefficient; **, the correlation is significant at the 0.01 level.
