Abstract:

This paper discusses how to produce and draw the most representative of the fractal structure of Diffusion Limited
Aggregation（DLA）model based on the fractal theories of iterative process, so that the process of particle dynamic growth and simulate the growth of plants are observed. By using the method of mathematical modeling for curve fitting, it establishes two more reasonable mathematical models of simulating plants growth, which are 3 polynomial model and index function model. They can predict the trend of plants growth, and realize the real-time monitoring of plants growth and estimation.

Key words: DLA model, 3 polynomial model, index function model
