本文探讨了陇南白龙江流域河谷浅山区冬季温度分布及逆温出现的特点;阐述了逆温形成的原因及与桔树生物学特性相适应的“逆温暖层”农业气候、生态的优势;根据冬季宏观温度和山体逆温分布规律,提出了浅山“暖层”宜桔地选择的方法。

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.
