摘　　要：依据根系生长发育过程中群体行为,构建了一种带偏好的群体交互模型,用于对虚拟根系可塑性的建模与仿真。视根尖作为根系群体中的智能个体。依据根尖个体对资源的竞争以及共享行为,构建根尖个体间交互模型。采用L系统构建简单动态根系生长模型,用于控制根系生长发育。结合群体交互模型与根系生长模型,在三种不同的土壤资源分布场景中分析群体行为对根系长度、根系在土壤中分布以及根系形态。结果表明群体交互影响下的根系生长能够感知土壤资源分布,并进行适应性的根系结构调整,从而为根系仿真提供一种简单的方法。According to swarm behavior in the process of root growth and development,a swarm interaction model with preference which is used to model and simulate plasticity of virtual roots is constructed. The root tip is treated as intelligent individual. Based on resources competition and sharing behavior of the root tips,the interaction model among the root tips is constructed. L system is used to construct a simple dynamic root growth model,which is used to control root growth and development. Based on interaction model and root growth model,the root length,root distribution and root morphology are analyzed in three different soil resource distribution scenarios. The results show that the root system can sense the distribution of soil resources and adaptively change root architecture.So it can provide a simple method to model root system.
