Redundancy analysis (RDA) for the chronologies and the monthly climatic factors at different altitudes (a) and slopes (b). Significant (p < 0.05) climatic factors are indicated by solid line arrows and named as “the climatic factor-corresponding month” (e.g., the mean temperature in July of the current year named as Tmean-C7). Arrow (vector) length and the cosine of the angle between two vectors depict the magnitude of variables and their correlation. The longer the vector, the more important the climatic factor. Vectors crossing at sharp angles, obtuse angles, and right angles, respectively, indicate a positive correlation, a negative correlation, and a near-zero correlation
