| 摘 要： | 脱氮脱碳模型(denitrification-decomposition,DNDC)是通过计算反硝化和有机质分解来模拟氮和碳从土壤丢失而转移入大气时的主要生物地球化学过程模型。作为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,整理了DNDC模型在碳动态模拟过程中的主要研究进展,总结了当前DNDC模型在碳动态模拟领域的应用热点和优势。

| Abstract: | The Denitrification-Decomposition (DNDC) model is a process-oriented computer simulation model of carbon and nitrogen biogeochemistry in agroecosystems by computing denitrification and decomposition process to simulate carbon and nitrogen transfer between soil and atmosphere,which is one of the most successful biogeochemistry models.In this paper,we reviewed the development of different versions of the DNDC model including those developed for different ecosystems.Also,we inducted carbon simulation papers in China agricultural research with DNDC,and summarized the advantages and hot spots in DNDC model utilization. |
