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。
This paper uses GIS technology to study the forest ecological benefits of urban park in Hefei, Anhui Province. By using this technology, this paper analyzes the forest ecological benefits of urban parks and discusses the technologies and methods of CITY-green model in the research of domestic forest ecological benefits. The results show as follows: (1) The urban forest of Xiaoyaojin Park and Xinghua Park respectively accounts for 52.62% and 13.00% of the total landscape of the park, indicating that the forest landscape in Xiaoyaojin Park occupies a larger proportion and the tall trees in the park are the major Plant landscape, and apricot flower park to lawn-based, low forest cover. (2) The comprehensive ecological benefits of the forests of Xiaoyaojin Park and Heng Fa Chuen Park are respectively 515.30 thousand yuan and 1.3543 million yuan; the ecological benefits of unit area (hm2) are 14.40 thousand yuan and 4.74 million yuan respectively. Show that Xiaoyaojin Park in the city to play the highest ecological benefits.
