| 摘 要： | 通过对暖温带落叶阔叶林林冠上层能量特征的观测，得出太阳总辐射库存3095-4368MJ.m^-2。光合有效辐射1038.3-1305.4MJ.m^-2，年总辐射与年降雨量呈负相关（R=-0.72)，总辐射最大原月份出现在5月，直射辐射和有效光合辐射变化具有相同特点，季节和月变化较为平稳，呈单峰曲线，最大值一般出现在5月或6月。

| Abstract: | Energy characteristics above stand canopy in warm temperate zone deciduous broad-leaved forests were observed. Gross radiation is 3 095 ~ 4 368 MJ. m-2. photosynthetic active radiation (PAR) l 038. 3 ~ 1 305.4 MJ. m-2. Gross radiation per year is reversibly related to annual precipitation. and the correlation coefficient is R=-0.72. Monthly maximum gross radiation is in May. The trends of direct radiation and PAR are similar. seasonal and month changes are smooth. show mono climax curve. maximum value was in May or June |
