Function - Structure And L-system-based Plant Modeling And Simulation,

Plant growth simulation model is the quantitative study of the growth of plants important means of its research in the agricultural and forestry research, green landscape design, education, entertainment,business and other fields have significant prospects and the application of practical value. Structure-function model is one of the most important plant modeling method ,and the distribution of biomass construction is the most difficult aspect, so far not a widely accepted view.This paper studies the physiology of plant biomass in the allocation process, and based on the function of the process-structure model of the mathematical model, based on experimental data and the model parameter calibration, as the L-form generator system through structure-function and L-system the integration of process simulation of plant growth. In addition, the design and development of the plant growth simulation and visualization system.The whole project shows as following, based on the basic principles of plant biology. The model taking into account the structural and physiological function of the interaction, can simultaneously simulate plant topology and geometry of the development and changes. Said that the plant, the overall topology to L-systems modeling; single organ images using textures mapping technology, the connection between the organ is based on the topology. Plants studied in this paper analyzed the function of the structure of a mathematical model of behavior, and model parameters on the plant growth and structure of the law. Check for the model provides an effective means.Model plant biomass on the distribution of the source - the model is extended to the source - the - pool model, this model is a more detailed model and easy to understand and use. Take into account biomass allocation and balanced expansion of its distribution process will be refined and is divided into two separate phases, each with corresponding functions.Practice has proved that the method is effective.To Visual C++ tools, the object-oriented program design, set design completed the simulation of plant growth and the integration of functions in plant growth model of software Plant. Software user friendly interface to provide graphics, such as curves and text mode showing plant biomass production and distribution, as well as the structure of plant growth dynamic process model can be easily adjusted initial parameters and objectives implied in the selection.This paper focus on the source-sink-pool distribution model and features -structure of the model simulation modeling, and on this basis the development of plant growth virtual software Plant, and the experimental results of a series of analysis and comparison, that the source-sink-pool programmers in the validity of the underlying structure.
