基于PL系统的形态生成模型

采用人工生命的基本方法，综合考虑了自然环境中阳光和重力对树木形态的影响，结合树木自身的生长基因，提出了一个以ＰＬ系统为基础的树木生长模型．该模型通过改变模拟系统自身的替换规则，使得系统可以随环境因素的变化自动调整所迭代的分枝模型，从而实现自然环境下树木形态的计算机模拟．介绍了模拟系统及计算方法，并给出了模拟结果．

Study on the Pattern Model of Plants Using PL System

It is an important research field on Artificial Life to set the pattern models and simulate the graphics of plants in natural enviroment by using the computer. In this paper, a plant growth model based on PL system is proposed to simulate plants under different surrounding conditions considering their growing genes. This model can modify its production rules automaticly to make the simulating system adjust itself adaptly. The research methord and simulation results are given.
