作者以等效积温划分温度带,能避免出现水平温度带与垂直温度带指标界限不一致的缺点,用于秦岭及其山麓地区温度带的划分,符合该地区的实际。

The equation of equivalent accumulated temperature is ΣT_e=(ρ₀/ρ)ΣT_h where ΣT_h and p are the active accumulated temperature and the air density from meteorological stations respectively; h is altitude, ρ₀ is the air density at sea level; Te is equivalent accumulated temperature. Using ΣT_e to divide vertical temperature zones in Qinling Mountain Range, the limiting indexes of temperature zones correspond with those of plain regions in the eastern part of China.
