摘要
通过对森林生态系统水源涵养功能进行定量评估，可以指导森林保护、水资源利用以及区域规划等。文章在分析森林生态系统水源涵养功能内涵的基础上，对现有的常用水源涵养功能评估模型进行归纳与分类，从经验模型和物理模型两方面综述森林生态系统水源涵养功能评估模型研究进展。论述了各类模型的主要特征、优缺点以及应用现状，总结了在湿润地区和半湿润地区的代表性应用成果，探讨了森林水源涵养功能评估研究中存在的问题，并讨论了森林水源涵养功能评估模型的主流研究方向。
To assess the water conservation function of forest ecosystem can guide the forest protection, water resources utilization and regional planning, etc. In this paper, based on the connotation analysis of the water conservation function of forest ecosystem, according to primary methods for water conservation function assessment of forest ecosystem, models were firstly classified as empirical models and physical models. In addition, the main characteristics, advantages, disadvantages and application status of those models were discussed. Moreover, some typical applications of the models in humid areas and sub- humid areas are summarized. Furthermore, the problems in the research of water conservation function of forest ecosystem were discussed. Eventually, mainstream research direction for water conservation function of forest ecosystem was considered.
