This paper reviewed the development history of the forest survey equipment and technology of domestic outside, summarized the current use of forest survey equipment and related technology, and concluded the development trend of equipment and technology which have been gradually developed to the intelligence, refinement and precision. Through the synergy of integration of aerial-space-ground, the developed equipment and technology enhanced the precision and accuracy of forest survey, improved the work efficiency of forest survey, reduced the waste of a lot of manpower and material resources, and built the forestry information platform at the same time. The platform was based on Internet and GIS technology, and it was built through the combination of software and hardware. The software mainly included traverse survey, coordinate sample, area calculation, volume calculation, single tree volume, section area per hectare determined, stand volume, statistical graph, statistical table, and forestry mapping etc., whats more, the information platform realized the application system with comprehensive functions of survey statistics, basic figure, stock map, forest distribution map and thematic map. In particular, the construction of forestry information platform promoted integration and intelligence of forestry resources survey. Forest survey system of aerial-space-ground was an inheritance and development of the existing equipment and technology. Therefore, the forest survey equipment enters into a new era featuring close relation with geographical information system technology, photogrammetry technology, remote sensing technology, information technology, space technology, image technology and graphics technology.
