5种红树植物光合产量模型研究

以木榄、白骨壤、桐花树、秋茄和海漆为试材,以光合作用对环境因子的响应为主线,建立了叶片水平上的光合产量模型。就光合作用对环境因子(太阳辐射、温度及CO2浓度等)变化的响应特征及合理性进行了分析,使用整个生长季实测的叶片生理数据对所建模型进行了验证,结果表明,模型可以较好的模拟实测红树植物的光合速率,并确定了5种红树植物单叶片光合作用与环境因子之间的数量关系。

Study on Photosynthetic Yield Model for Five Mangrove Species

The photosynthetic yield models of the photosynthesis were established at the level of leaves,with Bruguiera gymnorriz,Avicennia marina,Aegiceras corniculata,Kandelia candel and Excoecaria agallocha as the experimental materials,using the response of photosynthesis to environment as the main clue.The photosynthetic characteristics and rationality in response to environmental factors(solar radiation,temperature and CO2 concentration) were analyzed.The model was verified by the measured value of leaf physiological data in growing season.Result showed that the model could simulate the photosynthetic rate of mangrove well.The numerical relationship of leaf photosynthesis for the five mangrove species with environmental factors was explicated.
