| Abstract: | A navigational experiment of aerial seeding afforestation was made by adopting the Global Positioning system (GPS) and using GARMIN GPS 95 receiver. The results of the experiment indicates that average effective fallen seeds arte was 86.7% which exceeded the national level(85%) in aerial seeding site by GPS navgationing. The fiving operation time was decreased by 35% .The investment to navigation was decreased by 78%. |
