摘　　要：针对采用序列模型实现根分枝建模中不能实现根分枝可塑性的问题,提出一种基于群体Parrondo博弈的根分枝仿真方法,用于异质根系生长环境下根分枝可塑性建模。该方法首先通过构建根原基为个体的根原基群体,然后采用Parrondo博弈实现环境影响下根原基群体间的交互,最后依据根原基群体交互结果,实现根原基个体中生长素更新,从而对根分枝过程实现建模。在四种不同的根系生长环境中实现了对根原基发展成根分枝概率的预测。通过与Root Map等其他根分枝建模方法相比的仿真结果表明,所提方法能够依据根系生长环境中资源空间和时间变化,实现对根原基发展为根分枝过程的建模,从而为根系建模与仿真研究提供模型支撑和分析手段。To solve the problem that root branching plasticity cannot be achieved by using sequential model in root branch modeling,a new root branching method based on swarm Parrondo s game was proposed to analyze root branching plasticity in heterogeneous root growth environment.Firstly,root primordial swarm based on individual root primordium was constructed.Secondly,Parrondo s game was used to achieve interaction among root primordial swarm affected by environment.Finally,root branch modeling process was simulated according to auxin that was updated based on the interaction results of root primordial.Prediction of root branching probability was achieved in four different root growth environments.The experimental results show that compared with RootMap,etc,the proposed method can be used to model development process of root primordium into root branch affected by spatial and temporal changes in the growth environment of the root system,and also provides analysis means for root system modeling and simulation research.
