摘要/Abstract

摘要： 脱氮-分解（denitrificationdecomposition，DNDC）模型通过耦合土壤环境驱动的反硝化和分解过程来估计土壤中二氧化碳（CO₂）、甲烷(CH₄）和氧化亚氮(N₂O)等痕量气体的排放量，是目前国际上最成功的模拟陆地生物地球化学循环的模型之一.本文主要阐述了DNDC模型的发展过程及其结构，以及模型的验证和敏感因子分析，并总结了当前DNDC模型应用的热点领域.

Abstract: Denitrificationdecomposition (DNDC) model can estimate the emission fluxes of soil trace gases such as carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O) via the coupling of the denitrification and decomposition processes driven by soil environmental factors. At present, DNDC model is one of the most successful models in the world in simulating the terrestrial biogeochemical cycles. This paper mainly reviewed the development process of the DNDC model, its structure, model validation, and sensitive factor analysis, and summarized the hot fields in the applications of the model.
