This invention discloses a method and system for constructing a simulated plant model based on 3D modeling, belonging to the field of 3D modeling technology. The method includes the following steps: constructing a spatial association mapping of skeletal nodes; calculating initial values ​​of weight distribution between nodes based on spatial distance, angle, and torsion direction parameters; and performing adaptive weight redistribution operations on branch and joint regions based on the established initial weight distribution values. By dynamically adjusting the weight ratio along the energy conduction path, a smooth transition of weights is achieved at locations where the energy transfer rate changes. This invention, by constructing a spatial association mapping of skeletal nodes and initializing the weight distribution, combined with adaptive weight adjustment, energy direction tracking, and zonal constraint control, ensures continuous energy conduction along the skeletal path and introduces closed-loop feedback to dynamically update the weight relationship, thereby suppressing energy reflection and error accumulation, and improving the morphological continuity, mechanical stability, and long-term dynamic realism of the simulated plant model.
