Construction of Natural Disaster Early Warning System

Constructing an efficient natural disaster early warning system is regarded as a core means to enhance climate change adaptability，and also an effective approach to reducing casualties and economic losses. However，the current theories，technologies，and systems related to natural disaster early warning still face enormous challenges. Therefore，this paper systematically sorts out the scientific challenges and technical bottlenecks confronted by natural disaster early warning，proposes the overall architecture of the natural disaster early warning system，elaborates on the paths and key areas for the construction of China’s natural disaster early warning system in detail from three aspects：theoretical system，technical system，and national system，and conducts beneficial discussions on how emerging technical methods such as artificial intelligence，digital twin，and big data can promote the improvement of early warning capabilities.
