试论秦岭垂直温度带的划分

The Regionalization of Vertical Temperature Zones in Qinlin Montain

作者提出的等效积温表示式,用于温度带划分的指标界限值能避免出现水平温度带与垂直温度带指标界限值不一致的缺点。以之用于秦岭山区及其山麓附近的平地温度带的划分,均能较好地符合各地的实际情况。秦岭北亚热带在海拔700～800m以下(只限于南坡),暖温带上限为1200m,中温带、冷温带上限分别为2400m和3400m,在此高度以上为亚寒带。

The equation of equivalent accumulated temperature ∑Te=(ρo/ρ)∑Tk.is Where ∑Tk and ρ are the active accumulated temperature,and the air density from meteorological atations,respectively;h,is altitude;ρo is the air density at sea level; ∑Te is equivalent accumulated temperature. Using ∑Te to divide vertical temperature zones in Qinlin montain,the limiting indexes of temperature zones are correspond with those of plain region of the east party of China.
