Abstract:

In this paper, the application status and development trend of multi-source remote sensing in forest resource monitoring are described. Compared with traditional forest resource monitoring, which involves a large amount of manpower to carry out field investigation, satellite remote sensing and UAV remote sensing have obvious advantages in forest resource monitoring. In the forest resource monitoring research based on multi-source remote sensing data, this paper focuses on the comparison of the application of five kinds of multi-source remote sensing on forest resource monitoring, including: forest disease and insect monitoring, stand height measurement, forest canopy structure measurement, tree species composition and forest classification, and forest biomass measurement. Resource satellite, microwave remote sensing, imaging spectroscopy and new technologies and methods of forest resource monitoring in three-dimensional remote sensing, such as deep learning intelligent classification and multi-source remote sensing fusion technology, will become new means for multi-source remote sensing forest resource monitoring in the future. The application of differential GPS, three-dimensional remote sensing and hyperspectral images combined with mathematical computer technology can improve the accuracy of different levels of forest resource estimation. The automation and informatization of UAV remote sensing will be the development trend of UAV remote sensing application in forest resource monitoring. In addition, the long endurance capability and multiple types of sensors will further improve the accurate monitoring of forest resources by UAV remote sensing.
