摘　　要：区域地球系统模式是区域气候模式下一阶段的主要发展目标。本文阐述了发展区域地球系统模式的重要意义,分析了近年来区域地球系统模式的研究进展和典型案例,指出其多圈层通量耦合、空间分辨率提高以及耦合数据同化的三个共性特征。建议以开源共创的方式整合各界研究力量,加快建设我国自主可控的区域地球系统模式;围绕新建立的模式开展跨学科研究,特别关注其中多圈层、多尺度过程的相互作用;围绕高分辨率区域地球系统模式建立区域数字孪生监测预警平台,用于关键区域的防灾减灾和关键决策支撑。An accurate understanding of Earth system change mechanisms and predicting their impacts relies on the development of Earth system models.Compared to global models,Regional Earth System Models(RESMs)concentrate more on medium-to small-scale processes and their regional impacts within specific areas,featuring higher spatial resolution and more detailed physical processes.RESMs enable coupled simulations of multi-layered Earth interactions,thereby enhancing the ability to reproduce,analyze,and forecast extreme climate events.Consequently,the development and application of RESMs hold significant scientific and practical importance for addressing various climate change-related challenges and assisting in prediction and decision-making across multiple fields,including disaster prevention and mitigation,water resources management,agriculture,energy,environmental conservation,and resource exploitation.The concept of RESMs was initially proposed by Giorgi around 1995.Over the past three decades,their development has primarily followed two approaches.The first approach,known as independent development,involves coupling regional weather/climate models with specialized models tailored to specific application goals.This method aims to broaden the application scope of regional models in specific fields based on reliable atmospheric,land surface,and oceanic descriptions.Typically,specialized models are directly coupled with regional weather/climate models,resulting in relatively simple model structures and limited functions.Representative models include WRF-Hydro,PFWRF,WRF-HMS,RegCM-FVCOM,CWRF-FVCOM,WRF-Crop,WRF-CMAQ,and WRF-Chem.The second approach,holistic integration,seeks to construct a comprehensive model of coupled multi-sphere processes for digital twin regional Earth systems.This approach aims to create a unified and coordinated framework that emphasizes deep integration among various models.Such an approach not only requires technical compatibility among the models but also demands theoretical and methodological innov
