摘　　要：根据冬小麦根系分布的试验测量参数与生长规律,综合考虑根系生长的生理生态模型和虚拟植物模型,构造了描述小麦根系生长的动态模型.在已建立的根系生长模型基础上,运用分形几何理论与计算机图形学技术,对耕作土壤环境下冬小麦根系构型进行了三维仿真模拟.根据根系实测参数,对冬小麦根系生长模拟进行宏观控制,可以真实再现冬小麦地下根系部分的动态生长过程.According to the measured results of root system distribution in soil and synthetically taking the physiological model and virtual plant model of root system, a dynamical model for simulating the wheat root system growing was developed in present paper. Based on fractal brown mtion （FBM） and the developed roots system growth model, a three-dimensional visual simulation and analyzing software, which can repeat the dynamic growing course of winter wheat root system, was exploited by the using of the computer languages of Visual C ＋ ＋. net and OpenGL. By using the developed software, actual dynamic growing progress of wheat root system can be simulated, which might be useful for agricultural application.
