摘    要:DNDC(Denitrification-Decomposition, 反硝化-分解)模型是建立在元素丰度、 耦合、 循环和动力四个概念之上的生物地球化学模型。作为将生物地球化学理论应用于当前生态环境问题的桥梁, DNDC模型通过计算反硝化和有机质分解来模拟生态系统中碳氮循环过程, 其最终目的是计算目标生态系统中不同库间的温室气体排放通量。经过二十多年的发展, DNDC模型已成为目前国际上最成功的生物地球化学模型之一。文章阐述了DNDC模型的发展历程、 科学结构、 模型验证及校正, 总结了DNDC模型在生态系统应用中的主要研究进展及不足之处, 并对DNDC模型在高寒生态系统中的应用提出展望。

关 键 词:DNDC模型  温室气体  碳氮循环  高寒生态系统

Abstract:The Denitrification-Decomposition (DNDC) model is a biogeochemical model based on the concepts of element abundance, coupling, circulation and dynamics. As a tool of solving present environmental problems based on the theory of biogeochemistry, the DNDC simulates carbon and nitrogen cycles by calculating the decomposition of organic matter in denitrification process. The aim of DNDC is to calculate the greenhouse gas emission fluxes in different pools in the target ecosystem. During more than 20 years, DNDC has become one of the most successful biogeochemical models in the world. This paper mainly described the development, scientific structure, model verification and correction of DNDC, and pointed out the shortcomings of DNDC. We put forward the application prospect of DNDC in alpine ecosystem.
Keywords:DNDC model  greenhouse gas  carbon-nitrogen cycle  alpine ecosystem
