| 摘 要： | 本文通过对不同立地、不同年龄段长白落叶松净光合速率与呼吸速率的测定 ,测定出了长白落叶松净光合速率和呼吸速率 ,以及长白落叶松净光合速率的日进程与季节进程。通过对比试验测定 ,得出长白落叶松以 10年生净同化率最高 ,值为 :0 .30 51mgCO2 m- 2 s- 1,四大林场中以哈尔滨林场的长白落叶松净同化率最高 ,值为 0 .1335mgCO2 m- 2 s- 1。长白落叶松CO2 补偿点为 130vpm ,光呼吸值为 4 0vpm |
| 关 键 词： | 净光合速率 呼吸速率 净光合同化率 |

| Abstract: | Net photosynthesis rate and respiration rate of larix olgensis under different sites and diferent age stages,daily and seasonal courses of Larix olgensis was determined.The comparison test showed,that net assimilability at 10 years of Larix olgensis was higher than that at other ages,up to 0.3051 mg CO 2m -2 s -1 .Net assimilability of Larix olgenses on Harbin′s forest farm of the four was the highest,up to 0.1335 mg CO 2m -2 s -1 .The compensation point of the pine was 130vpm.The value of light respiration was 40vpm. |
| Keywords: | net photosynthesis rate respiratory rate net photosynthesis assimilability |
