Abstract: In the graphics information management of forest resources, the current state and dynamics of the subcompartments borders derived from forest resources inventories always face with the issue of dynamic update of the borders data. Aiming to this, the adjoining polygon structure is used to depict borders and the concept of class of the object oriented programming language, a storage manner for the adjoining polygons is constructed. The corresponding algorithms is further developed in this work. Ultimately, a dynamic and gradual polygon search algorithm was realized. The static storage manner of polygon data blocks and the topological polygons reconstruction was supported in this polygon data structure.
