摘　　要：城市森林的生态服务功能对改善城市环境质量具有重要作用,如何量化这些生态服务功能是使城市森林发挥最大效益的一个重要前提。随着科学的发展,对城市森林经济效益评估的量化方法已由传统的CTLA法、Burnley法、碳税法、造林成本法等发展到模型测算法。本文介绍的i-Tree模型是由美国林务局(USDAForest Service)于2006年开发的城市森林效益评估软件,具有许多其他模型如CITYgreen模型等不可替代的优势,在国际城市森林研究中已得到了广泛的应用,但国内尚未推广。本文主要阐述和评价了模型中UFORE和STRATUM两个主要模块的研究及应用进展,通过作者在国内的应用实践,讨论了该模型在中国的应用前景及存在的主要问题,为城市森林管理提供科学依据。Urban forest provides numerous benefits in improving the environmental quality in and around urban areas.To quantify the ecosystem services of urban forest is an important prerequisite to make the maximum use of the services.With the advancement of research work,the methods for evaluation urban forest economic benefits have developed from CLTA method,Burnley method,carbon duty method,and reforestation cost method to model calculation method.In this paper,the i-Tree model developed by the USDA Forest Service in 2006 was introduced.Comparing with other models such as CITYgreen model,the i-Tree model has many irreplaceable advantages,and been widely used in international urban forest research but not in China.Here,the research and application progress of this model were described and evaluated from the aspects of the benefits quantified by the UFORE and STRATUM modules in the model,and,based on our domestic practices,the prospects and main questions in using this model in China were discussed.
