L系统理论在植物根系生长模拟中的应用研究

Simulation of Plant Root Systems Growth with L-systems Theories

根据植物根系生长的几何特征,探讨了L系统理论在植物根系生长模拟中的具体应用。把括号L系统、参数L系统、随机L系统和时变L系统等结合起来,建立了描述植物根系生长的产生式集,实现了直根系植物根系生长的三维可视化,表达了根系生长的随机性特征和图形随时间变化的连续性。

According to the geometric character of the plant root systems, application of the L-systems theories in simulating the plant root systems growth was studied. The theories of Bracketed L-systems, Parametric L-systems, Stochastic L-systems and Timed L-systems were combined, the L-systems productions which could describe the plant root systems growth were written out, the three-dimensional visualization of the plant tap root systems was realized, the stochastic and fractal features of the growth of the plant root systems were presented, the continuity of the graphics varied with time was realized.
