Abstract: In recently, more and more researchers are focus on the virtual plant functional-structural modeling with physiological characteristics. This paper studies the expression of plant morphology and the allocation method of the carbon biomass in plant tissues and organs, and proposes a functional-structural modeling method based on the multi-modules to model the plant growth. The method uses a custom light response curve to simulate the carbon biomass, and achieves the carbon biomass allocating among the organs of the plant. Using the method of the L+C multi-modules realizes the dynamic growth of leaves and internodes. Through simulation on the growth of Arabidopsis, it proves that the method is practical and valid.

摘要： 花卉植物生长模拟中，构建反映植物形态和生理特征的功能结构模型是目前虚拟植物的研究热点。对植物形态结构的表达方法和碳汇生物量在植物组织器官间的分配方法进行了研究，基于多模块方法实现了功能结构相统一的虚拟花卉植物生长模拟。利用自定义的光反应曲线模拟碳汇生物量，基于源汇理论实现了碳生物量在器官间分配，利用L+C 多模块方法实现了植物叶片和节间的动态生长。通过对拟南芥植物的生长模拟，证明了方法的实用性和有效性。
