图1 5个研究点平均气温(Ta)、最高气温(Tmax)、最低气温(Tmin)、降水量(P)、饱和水汽压差(VPD)、标准化降水蒸散指数(SPEI)的年变化。直线表示气候因子变化显著(p < 0.05)。样地CH、KL、LS、TS、XY见表1。

Fig. 1 Trend of annual average air temperature (Ta), annual maximum air temperature (Tmax), annual minimum air temperature (Tmin), annual precipitation (P), vapor pressure deficit (VPD) and standardized precipitation evapotranspiration index (SPEI) in the five study areas. The straight line represents significant changes in climate factors (p < 0.05). Site LS, CH, XY, TS and KL see Table 1.
