甘肃白龙江河谷浅山区冬季温度分布,逆温特征及宜桔地选择

In this paper, the distribution of temperature in winter and the features of inversion in the shallow mountain area of the Bailongjiang valley of south Gansu are analysed. Also the causes of inversion occurrence and the agroclimatic ecological superiority of the warm layer of inversion which adapts to the biological characteristics of citrus trees are expounded. Finally, on the basis of the macroscopic temperature in winter and the distribution rules of orographic inversion, the method of selecting the adaptive fields for citrus in the warm layer in the shallow mountain area is proposed.
