摘　　要：围绕基于动态生长模型的植物根系模拟技术展开研究与讨论,在分析了冬小麦根系动态生长模型的基础上,提出了一种利用改进型L系统规则结合动态数据结构的冬小麦根系模拟方法并予以实现。引入了植物根系的“管道模型”,使系统在模拟根系生长的同时,能完成对根系各生长参数的计算,最后能生成根系图形并计算出根系研究所需要的根长、根重、根体积等重要参数,实现了根系生长发育模型和形态发生模型的有机结合。On the basis of analyzing the dynamic growth model of winter wheat root system, a new means is put forward and realized that combines the improved L-system with the dynamic data structure to simulate the root system of winter wheat. When the growth of the root system is simulated, its growth data can be computed by means of the ＂pipe model＂. Finally, a program is fulfilled that combines the growth model of the root system with its morphogenetic model. It can create the images of the root system and compute important parameters for root system studies such as root length, root weight and root volume.
