Abstract: An efficient technology of 3D laser scanning has a great potential application in forest resources survey,stand structure research,and three-dimensional model of a single wood.The space point cloud data of single standing tree acquired by 3D laser scanner could directly measure information such as standing wood height,diameter,crown area and location by software of automatic modeling and analysis function.The generated forest harvest report could identify the forest harvesting time of different regions to minimize the loss caused due to harvesting time,which would create a new application of the technology in the field of forestry.

Key words: 3D laser scanning, forest tree production, digital forestry, three-dimensional model
