基于CITYgreen的城市森林生态效益评估的应用

The Application of CITYgreen Software to the Assessment of Ecological Benefits of Urban Forest

城市森林是城市生态系统的重要组成部分,了解并量化城市森林所产生的效益是使城市植被发挥最大效益的一个重要前提.综合了城市森林生态效益评价从定性到定量的分析过程,介绍了美国林业署开发的C ITY green模型的城市森林生态效益评价模块,并综述了该模型在国内外的应用现状,探讨了该模型在我国城市森林生态效益评价的应用前景.

Urban forest is an important part of urban ecosystem. To understand and quantify its benefits is an important prerequisite to make maximum use of the benefits. This article puts forward an coo--benefits assessment process of urban forest from qualitative analysis to quantitative analysis. It introduces the coo-benefits research and modeling functions of CITYgreen model developed by the Administration of American Forestry, and summarizes the applications of this model in and out of the country. Finally, it discusses the parameters of the model that still needs revising when used in China.
