数字孪生海岸带Digital Twin Coastal Zone

数字孪生海岸带：
从临界信号到多轮情景推演Digital Twin Coastal Zone: from tipping signals to multi-round scenario reasoning

数字孪生海岸带耦合多源观测、区域地球系统模式、临界诊断和情景推演。真实海岸带校准模拟海岸带，模拟海岸带反向解释临界信号、比较发展路径并识别可干预窗口 The digital twin coastal zone links multi-source observations, regional Earth system models, tipping diagnostics, and scenario reasoning. Real coastlines calibrate the simulated coast, while the simulated coast interprets tipping signals, compares development pathways, and identifies intervention windows.

真实海岸带与模拟海岸带动态互馈The real and simulated coasts update one another

数字孪生海岸带把智能化数据融合观测与海岸带区域地球系统模式放在同一计算环境中。观测约束实时状态，模式表达自然过程与社会经济过程互馈，临界判据连接诊断和推演 The digital twin coastal zone builds on two technical capabilities: intelligent observation provides a real-time, multi-source, interpretable data foundation, while coastal regional Earth system models simulate feedbacks between natural and socioeconomic processes. The digital twin system turns data, models, and tipping-dynamics diagnosis into an interactive, scenario-oriented decision-support platform.
