摘　　要：传统的根系研究模型注重于根系外观形态的模拟,而将根系的生理生态结合起来的模拟方法则较少。对于农业信息技术而言,根系生理生态的研究模型能更好地服务于农林业领域。文中在研究了DLA模型的特点及其应用的基础上,分析了基本DLA模型的不足并提出了一种改进的DLA模型,用于植物须根系的向水性模拟。该模型结合参数可控方法体现了植物须根系向水性的动态生长过程,一定程度上符合实际植物的生长机理,并在VC++6.0上给出了模拟效果图。模拟结果显示,改进的模型能够逼真、细腻地模拟须根系的向水性生长形态。最后指出了改进DLA算法关于根系建模进一步的研究方向。Most traditional research models of roots simulate shape of appearance,simulating methods combining physiological ecology of roots are less.Research model of physiological ecology of roots can make better performance in agriculture and forestry field for agricultural information technology.It analyses shortage of basic DLA model based on studying character of DLA model and application,proposes an improved DLA model,which is applied in simulating hydrotropism of roots.The model combining the method of controllable parameters shows that it is better in simulating the hydropism growth process for virtual plant roots,which agrees to growth mechanism of real plants.Simulation designsketch is realized using VC＋＋ 6.0.The simulation results show that the improved model realistically and delicately simulates the beard roots hydrotropism growth morphology.The end of the paper points out the future research direction for the improved DLA on roots system simulation.
