After four months of observation of the growth season, the author reveals in the thesis the day- and month-dynamic characteristics of the net photosynthetic rate of Dahurian Larches, which are of different ages, densities and stand classes. The author also compared the net photosynthetic rates of the leaves on different-age braches and with the crowns of different layers and directions. In addition, the author analyzed the effects of some ecological factors on net photosynthetic rate as well.

通过生长季节四个月的定株观测，揭示兴安落叶松的光合特征，即不同年龄、密度、分级木净光合速率的日动态和月动态特征，比较树冠不同层次、不同方向和不同枝龄上针叶的净光合速率的日动态和月动态特征，分析光照强度、温度、CO2浓度等生态因子对兴安落叶松净光合速率的影响。
