功能-结构植物模型的一个关键问题是资源在植物成分之间的分配。解决这一问题的一种方法是基于对资源的源和汇之间的传输的模拟。为此，我们利用了工厂中的资源流动和电路中的电流之间的类比，并提出了一种计算上有效的方法来求解该电路。该方法易于使用L系统直接实现，因此非常适合于模拟生长植物的空间显式模型中的资源划分。
A key problem of functional-structural plant modelling is the partitioning of resources between plant components. One approach to addressing this problem is based on the simulation of transport between the sources and sinks of a resource. To this end, we exploit an analogy between the flow of resources in a plant and the flow of currents in an electric circuit, and we present a computationally effective method for solving this circuit. The method lends itself to a straightforward implementation using L-systems, and is thus well suited for simulating the partitioning of resources in spatially-explicit models of growing plants.
