茶树（Ｃａｍｅｌｉａｓｉｎｅｎｓｉｓ）叶片光合速率（Ｐｎ）与光照强度（Ｌ）、气温（ｔ）多元相关呈极显著水平，其回归方程可作为光合速率估算的模型；日光合量与平均气温呈极显著正相关，呼吸速率与气温呈极显著正相关，其回归方程均可作为叶片日光合量、呼吸速率的估算模型．茶树的年净光合量、年呼吸量估算结果分别为３．４３×１０４ｍｇＣＯ２·ｄｍ－２·ａ－１和３．５３×１０４ｍｇＣＯ２·ｄｍ－２·ａ－１．
The photosynthetic rate (Pn) of Camellas sinensis was significantly correlated with the light intensity (L) and air temperature (t), and the regression equation could be used as a model to estimate the photosynthetic rate. There was a significant positive correlation between photosynthesis and the average temperature , Respiration rate and temperature were extremely significant positive correlation, the regression equation can be used as leaf photosynthesis rate, respiration rate estimation model. The annual net photosynthesis and annual respiration of tea trees were 3.43 × 104 mgCO2 · dm-2 · a-1 and 3.53 × 104 mgCO2 · dm-2 · a-1, respectively.
