全球及区域碳模拟与源汇同化反演研究进展

近年来，全球和区域碳模拟与同化反演系统(简称“碳同化系统”)快速发展，并被广泛应用于不同时空尺度的碳通量和碳汇估算、碳排放量校核研究中，为支撑全球碳盘点提供了关键技术手段。文章回顾了国内外主要碳同化系统的发展历程和应用案例，总结了当前常见的全球和区域碳同化系统的结构和特点，包括使用的大气传输模式、同化方法、空间分辨率等内容；探讨了当前常见模型系统应用中的关键问题、不足与发展方向，以期为碳同化系统应用于我国环境管理和气候变化工作提供参考。

Research Progress on Global And Regional Carbon Modelling and Source-Sink Assimilation Inversion

In recent years,global and regional carbon dioxide simulation and assimilation inversion systems (hereafter,carbon assimilation systems) have been developed rapidly,are widely used in carbon flux and carbon sink estimation,carbon emission verification research at different temporal and spatial scales.These modeling systems provide critical technical tool for the inventory of global carbon dioxide.This paper reviews the development history and application cases of major carbon assimilation systems at nationwide and abroad,summarizes the structure and characteristics of mainstream global and regional carbon assimilation systems,including the atmospheric transport model,assimilation method,spatial resolution,etc;This paper also discusses key issues,shortage and directions in the application of current common model systems,in order to provide reference for the application of carbon assimilation systems to environmental management and climate change in China.
