| Abstract: | Dynamic changes of the forest lands managed by Hongxing Forestry Bureau were investigated by remote sensing images of GF-1 and other resources.Through visual interpretation,identification and extraction of the images,situations of forest resources were obtained from the aspects of harvesting,deforestation,occupation,reclamation,and forest disaster.The results showed that the interpretation accuracy for high resolution images on the dynamic variations of forest lands was more than 95%,indicating that the visualization analysis methods and techniques could be considered as an effective mean to monitor forest resources,and it could provide technical support for the national forest land management and forest harvesting. |
