摘要: 本文所作的中国气候区划,采用等效积温作为第一级温度带指标,千操度作为第二级干湿气候型指标。区划结果表明,等效积猛指标在高原和平原有较好的一致性。

Abstract: The climate regions of China are distinguished by the equivalent accumulated temperature as the first index of temperature zone and aridity as the second index of climate type of moisture.The equation of equivalent accumulated tempearature is
ΣTe=(ρ0/ρ)ΣTh
where ΣTh and ρ are the active accumulated temperature,and the air density from meteorological stations,respectively;h is altitude;ρ0 is the air density at sea level;ΣTe is equivalent accumulated temperature.Using equivalent accumulated temperature to divide temperature zone in both the Yunnan-Guizhou Plateau and the Qinghai-Xizang Plateau,the limiting indexes of temperature zones correspond to those of plain region of east China.
