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.
