Abstract
In this paper, the cultivars of Pinus koraiensis and Japanese larch varieties in Liaoning Province were studied. Aiming to solve the problem of data update difficulty and lack of information management, the Kriging interpolation method and UAV (Unmanned Aerial Vehicles) and GPS technology positioning method were used for fine positioning of the improved varieties of forest seed base. Using linear comparison and distributed comparison method for accuracy assessment, 100 Pinus koraiensises were sampled by liner comparison method among which 10 were selected to be tested by distribution comparison method. With the help of the high density total station, the samples were measured and analyzed by the coordination. It showed the positioning accuracy was less than 1m, which met the need of the production of the forest seed base. On this basis, the tree seed production management information base database was established and the database structure design and structure design was made. Therefore, the managers in the forest natural reserve could use the database to plan and do the daily management, measure the area, the circumference, and the coordination of the forest natural reserve. In this way, the field work was lightened and it also provided support for the seed base management and production.
