遮荫环境下的植物生长建模及仿真

Modeling And Simulation of the Grownth of Plant In Shade Environment

为了解决遮荫环境下的植物对光照资源的竞争和分配问题,更真实地仿真自然界中植物的生长情况,而采用了一种基于FON(field-of-neighbourhood)模型的植物生长建模及仿真的方法。方法用FON模型描述植物对光照资源的需求范围,引入植物学中遮荫率因子作为影响光照强度的一个因素,并提出了一种基于计算阴影重叠区域面积的光照资源分配策略。在实现过程中建立了一个支持植物共享光照资源的生长仿真系统,给出了不同竞争地位的植物在共享光照资源上所表现出的生长情况的可视化结果,对计算机仿真植物生长以及指导农林生产方面都具有积极意义。

Based on the FON - Model, a method is presented to model the light resource competition and allocation in shade environment, so the growth of plants can be simulated more realistically. In this method, the scope of light resource required by plant is described with the FON - Model, meanwhile, the plant shading rate of botany is introduced as a factor affecting light intensity. In addition, a light resource allocation strategy is introduced according to the overlapping area of shadow. To visualize the growth of plants with different competition status, a light shared environment plant growing simulation system is built, which has a positive impact on the computer simulation of plant growing, as well as the guide of agriculture and forestry.
