摘　　要：Based on the GIS technology, CITYgreen computer model was used in this paper to estimate ecological benefits of urban forest in the park of Hefei city.It used this technology to make an analysis on urban forest ecological benefits. The research discussed how to use the technology of CITYgreen model developed in USA to account urban forest benefits in China. The results showed that forests in Xiaoyao Jin Park occupied about 52.62% of park land area and Xinghua Park13.00% respectively, indicating that Xiaoyaojin Park is dominated by large trees such as arbors, and Xinghua Park dominated by laws, with low coverage. Besides,the comprehensive eco-benefits of Xiaoyaojin Park and Xinghua Park were 5.150 3and 1.354 3 million yuan and per unit area eco-benefits were 144 000 and 47 400yuan/hm^2, which indicated that Xiaoyaojin Park makes the greatest contribution in ecological benefits.该文运用GIS技术,对安徽省合肥市城市公园森林生态效益进行研究,运用该技术对城市公园森林生态效益进行分析,探讨CITY-green模型在国内森林生态效益研究方面的技术与方法。结果表明:(1)逍遥津公园和杏花公园的城市森林分别占整个公园景观构成的52.62%和13.00%,表明逍遥津公园公园内森林景观所占比重较大,公园内以高大乔木为主要植物景观,而杏花公园内以草坪种植为主,森林覆盖率较低。(2)逍遥津公园与杏花公园的森林所产生的综合生态效益分别为515.03万元和135.43万元;单位面积(hm2)生态效益分别为14.40万元和4.74万元。表明逍遥津公园在城市中发挥的生态效益最高。
