北极航道环境数字化服务及应用研究OA

[Background]Climate warming has led to a continuous reduction of Arctic sea ice,and has provided new routes for global transportation and international trade.Arctic navigation has shifted from the exploration stage to a period of development.During the low-ice season,melt-ing,or freezing periods in the Arctic Ocean,the timely acquisition of environmental informa-tion on Arctic sea routes is crucial for ensuring safe navigation.[Objective]This paper aims to enhance the acqui-sition,service,and digital application capabilities of Arctic routes environmental information based on aerospace data,Artificial Intelligence(AI)based forecasting technologies,and a comprehensive navigability index.It seeks to develop a digital service system for Arctic route environmental conditions to support navigation safety and en-vironmental governance in the Arctic.[Method]Focusing on the current accessibility of aerospace data,the study identifies essential environmental variables affecting Arctic sea routes.Based on traditional navigability indices,it incorporates additional environmental factors such as precipitation,air temperature,water vapor,sea surface temperature,and wave height to construct a comprehensive navigability assessment model.Furthermore,a route environmental information service system based on aerospace data is developed to provide multi-level support for Arctic emergency response,annual planning,and medium-to long-term strategic decision-making.The system has demonstrated practical effectiveness in supporting China's exploratory Arctic voyages and extreme-environ-ment Arctic expeditions.[Conclusion]By integrating essential environmental variables of Arctic sea routes,multi-source spatial data,sea ice forecasting technologies,and navigability assessment models,the system estab-lishes a layered service strategy.It provides an essential digital tool for Arctic route environmental information services,navigation safety,and environmental governance.
