图4 油松整轮、早材和晚材年表与气候因子的相关系数。样地CH、KL、LS、TS、XY见表1。EW, 早材; LW, 晚材; RW, 整轮。P, 降水量; pre, 上年; SPEI, 标准化降水蒸散指数; Ta, 平均气温; Tmax, 最高气温; Tmin, 最低气温; VPD, 饱和水汽压差。*, p < 0.05; **, p < 0.01。

Fig. 4 Correlation between total ring width, earlywood width and latewood width chronology of Pinus tabuliformis and climate factors. Site CH, KL, LS, TS, XY see Table 1. EW, earlywood width; LW, latewood width; RW, total ring width. P, precipitation; pre, the last year; SPEI, standardized precipitation evapotranspiration index; Ta, mean air temperature; Tmax, maximum air temperature; Tmin, minimum air temperature; VPD, vapor pressure deficit. *, p < 0.05; **, p < 0.01.
