| 摘 要： | 根据C3、C4植物生态生理过程中植物叶水平的光合同化机制过程和植物叶片尺度的光合作用限制函数方程。采用单叶光合作用模式进行C3、C4植物光合模拟试验,模拟不同环境影响因子对C3、C4植物光合作用的影响。结果表明,植物叶尺度光合作用模型能较好地模拟不同环境影响因子下的C3、C4植物光合作用状况。本文依据C3、C4植物光合生理特性进一步分析植物光合作用的三个限制函数方程在C3、C4植物光合的不同作用,揭示吸收光合有效辐射(PAR)、叶内温度(Tc)和CO2浓度(Ci)的敏感性。结果可用于植被—大气相互作用的能量和碳同化过程的物质交换研究。

| Abstract: | In this paper,we used the algorithm of leaf net photosynthesis models(considering Rubisco-limted,light-limited and CO2-limted based upon C3,C4 plants biochemical and physiological properties),and simulated the single leaf net photosynthesis,which acts as a function of different light,carbon dioxide and temperature conditions.The relationships between leaf net photosynthetic rate of C3 and C4 plants with CO2 concentration intercellular,leaf temperature,and photosynthetic active radiation(PAR) were presented,respectively.The results showed that the numerical experiment can indicate the main characteristics of plant photosynthesis for C3 and C4 plants,and further can be used to integrate with the regional climate model and act as land surface process scheme,and better understand the interaction between vegetation and atmosphere. |
