A System Dynamics Approach To The Modelling Of Complex Natural Systems

The research of complex natural systems is of huge importance, especially considering natural and ecological preservation. However, the problem of studying such systems is exactly manifested in its complexity, which is hard to describe and analyze through classic research methods, mostly based on linear connections between the elements of the observed system. A certain level of insecurity which is always present in the natural processes has to be built into a model. Therefore, the development of a simple and clear model of natural systems is a challenge which demands good knowledge of methodology and system itself. The nature of processes inside the complex natural systems as well as their environmental interactions mostly characterizes nonlinear causeeffect links which could be described and analyzed only within one system dynamics approach. The research of system dynamics approach of modelling and simulation of the complex natural systems will be conducted on the example of phenological phases of forest tree ́s leaves.
