摘要: 本文通过建立长白落叶松(Larix olgensis)幼苗在受控环境条件下的净光合速率与温度和CO2 等因子之间的关系,模拟了在受控条件下长白落叶松幼苗的日净光合速率进程与生长季中日干物质积累过程,并预测了在温度与CO2 浓度改变后干物质积累的变化。

Abstract: The model based on relations between net photosynthesis of Changbai larch (Larix olgensis)seedlings and temperature, CO2 concentration and other factors has been constructed. This model simulates the daily process of net photosynthesis and dry matter accumulation of Changbai larch seedlings in the growing season under controlled environment, and predicts the possible change of dry matter accumulation under changed temperature and CO2 concentration.
