中文摘要：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．

外文摘要：The polycorrelations of photosynthetic rate( P n),light( L ) and temperature( t ) of the leaves were the most significant, and the regressive formula could be used as the model to estimate the photosynthetic rate. Meanwhile, the correlations of the daily P n and the mean air temperature, the respirational rate and the temperature were so significant that both the regressive formulas could be used to estimate the yearly P n and the respirational rate of leaves respectively. The results based on these models of yearly net P n and yearly respiration of C. sinensis were 3.43×10 4 and 3.53×10 4 mg CO 2·dm -2 ·a -1 .
