Abstract: The characteristics of suddenness and periodicity of forest disaster have caused great difficulties for monitoring and investigation,and with the rapid social and economic development,comprehensive artificial ground survey methods face serious challenges.In the next decade,earth observation capabilities will increase rapidly,which provides a basic guarantee for near real-time monitoring of forest resources.This paper mainly discusses the key technology of application of domestic high spatial resolution remote sensing data,and describes its guiding role in the improvement of existing systems of ground investigation.A prototype system has been designed and developed for provincial and county-level applications,so that the potential of domestic high spatial resolution remote sensing in forest disaster monitoring can be demonstrated.

Key words: forest disaster, high spatial resolution remote sensing monitoring, supplementary investigation, technical system
