我国灾害遥感的作用、现状及发展

本文从现代遥感技术系统的构成和特点出发,论述了遥感在减灾活动,包括预警、监测、评价和辅助决策中的重要作用。并在回顾我国灾害遥感现状的基础上,提出了今后发展的设想。作者认为:建立实用性的重大自然灾害遥感监测评价技术系统,是今后我国灾害遥感发展的中心环节和主要任务。该系统应包括航天遥感宏观监测系统,航空遥感全天候、实时监测系统,地面灾害及背景监测系统,灾害及背景数据库系统,灾害分析、评价与辅助决策系统以及灾害防治救援通讯指挥系统。

EFFECTS, CURRENT STATUS AND TENTATIVE IDEAS ON REMOTE SENSING OF NATURAL HAZARD IN CHINA

Based on the characteristics of Remote Sensing techniques, it is discussed in detail that these techniques play a very important role in natural hazard mitigation activities, such as early warning, real time monitoring, quick assessing and decision making. After briefly reviewing the current status on Remote Sensing of natural hazard, some tentative ideas are presented. Author firmly believes that it is a main and very emergency task to develop an operational remote Sensing technologcial system for monitoring and assessing of natural hazards in China. The System will consist of (1) Satellite Remote Sensing monitoring system; (2) Airborne Remote Sensing monitoring system with all-weather, real-time and flexible capabilities; (3) Ground based monitoring system; (4) Natural hazards and their backgroud data base system; (5) Hazard analysis, assessment and decision making support system and (6) Communication and command system for natural hazard mitigation.
