森林灾害的突发性、周期性特点为监测调查带来很大困难,且随着社会经济的快速发展,全面的人工地面调查方法面临严重挑战。今后十几年我国对地观测能力的极速提高,可为森林资源的准实时变化监测提供基础保障。阐述了国产高分遥感数据应用的关键技术方法,展示了其在完善现有地面调查体系中的指导性作用,设计开发了适宜于县或省级应用的原型系统和技术体系,以期为国产高分数据的森林灾害监测应用提供技术示范和支撑。
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.
