The dynamic tendency of Pn, TR, gs and the relevant ecological factors and correlation analysis showed that, Pn and gs of leaves during pre-winter period were affected by both temperature and PAR, but TR was cotrolled by temperature only.

• Pn,TR和gs与有关生态条件的相对变化方向及相关分析表明,冬前叶片Pn和gs受气温和光合有效辐射(PAR)的双重影响,而TR主要受气温的影响。
