摘要
运用GIS技术,对安徽省合肥市城市公园森林生态效益进行分析,探讨CITYgreen模型应用在国内森林生态效益研究方面的技术与方法。结果表明: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;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515.03万和135.43万元,单位面积生态效益分别为14.40万和4.74万元/hm2,表明逍遥津公园在城市中发挥的生态效益最高。
Based on the GIS technology, the ecological benefits of urban forest park in Hefei City, Anhui Province was studied. The tech- nique and method for applied CITYgreeu model in forest ecological benefit research in China was discussed. The results indicated that wood- land patches in Xiaoyaojin Park occupied about 52.62% of park land area and Xinghua Park 13.00% respectively, indicating that there are more big trees and higher canopy coverage in the parks of Xiaoyaojin which was built in 1950＇ s to 1960＇ s, but larger area lawn becomes major landscape, while low canopy coverage was in Xinghua Park built in 1990＇ s. According to integrated benefits of woodlands, Xiaoyaojin Park reached to 5. 150 3 million yuan and was listed at top, then Xinghua Park 1. 354 3 million yuan in lower. If it was listed in accordance with benefits per unit land area, Xiaoyaojin Park was at the top with its benefits of 144 000 yuan per hector, then Xinghua Park 47 460 yuan/hm^2. It shows that the Xiaoyaojin Park has the highest ecological benefits compared with Xinghua parks.
