摘要:
分析了现有的植被对大气CO2浓度影响模型——地球化学模型和生态学模型的主要技术特征;针对较为有前途的生态学模型,就模型的基础数据,模型的结构和模型内的函数参数等三方面,讨论了现有模型的技术缺陷和可能的改进措施;最后,进一步研究了发展新的生态学模型的两条途径,并提出一种新的机理型生态学模型的构架。

Abstract:
Technical characteristics of two sorts of models, i.e. the geo chemical model and the ecological model, are critically reviewed in this paper, concerning the influence of terrestrial vegetation on the concentration of atmospheric CO2.The existing technical weakness of ecological model, especially involving data accuracy, model structure and function for-mulisation, are inquired in detail with relevant suggestions for improvement provided.Two ways for developing new ecological models are examined, and a framework of mechanism-based ecological models is proposed, which is considered beneficial to reveal some new nature of interactions between the concentration of atmospheric CO2 and terrestrial vegetation.
Key words:  Vegetation  CO2  Global carbon cycling  Ecological ,model  Geo-chemical model  Greenhouse effect.
