农田生态系统中的氮循环是影响农业生产力的主要因素之一,同时也会对环境产生影响。在农田生态系统氮循环的研究中模型已成为重要的工具而受到人们关注。在介绍国际上发表的模型基础上,阐述了目前一些比较成功的模型的研究进展,并指出了今后模型发展的趋势。
Nitrogen cycling in farmland ecosystem is one of the key factors to affect agricultural productivity and at the same time it affects the environment. Modeling nitrogen cycling in studying farmland ecosystem has been an important tool and has been paid much attention. This paper describes successfully used models based on summarizing some published models and ends off with presenting the trends and challenges for future farmland ecosystem models.
