摘要	Evergreen sclerophyllous oaks (the E. S. oaks, Quercus section Heterobalanus) are the dominant species of the local ecosystem in the eastern Himalaya and the Hengduan Mountains, southwest China. In this study, we document the climatic envelope of the seven E.S. oak species and examine the relationships between climate and their distribution. This was done using a principal components analysis (PCA) and multiple regression analysis (MRA) of nine climatic indices. The main climatic envelope of the E.S. oaks were: mean temperature of the warmest month (MTW)=12.0-19.5 degrees C, warmth index (WI)=33.2-88.9 degrees C month, annual biotemperature (BT)=-6.9--0.3 degrees C, coldness index (Cl)=-30.4--10.1 degrees C month, mean temperature of the coldest month (MTC)=-3.7-3.0 degrees C and annual precipitation (AP)=701-897 nun at the lower limits; and MTW=8.3-16.1 degrees C, WI=15.7-59.1 degrees C month, BT=3.6-8.9 degrees C, CI=-55.4--19.3 degrees C month, MTC=8.3-16.1 degrees C and AP=610-811 mm, at the upper limits. The climatic range of the E.S. oaks is wide and includes two climatic zones, the cool-temperature zone and the subpolar zone. The PCA and MRA results suggest that the thermal climate plays a major role and precipitation plays a secondary role in controlling the large-scale distribution of the E.S. oaks, except Quercus monimotricha. In thermal regimes, BT and/or MTW are most important for both lower and upper limits of the E.S. oaks. Furthermore, our results indicate that the upper distribution limits of the E.S. oaks are less determined by low temperatures and their duration (CI) than by other factors.
