摘　　要：运用大尺度区域分析方法,以昆明市建成区为研究对象,基于ArcView3.3和CITYgreen5.0模型,利用QUICKBird影像图,对昆明市建成区内的官渡区、盘龙区、五华区和西山区的园林绿地系统进行了生态效益分析,主要包括碳储存和吸收、清除大气污染物、释放氧气等方面的效益,并将这些效益转化为相应的经济价值。结果表明:昆明市建成区园林绿地系统2008年碳储存总量为788.92万t,当年碳吸收总量为6.04万t,折合人民币95.394 8亿元;清除大气污染物总量为2 398.864t,折合人民币7 767.45万元;释放氧气总量16.04万t,折合人民币5 945.90万元。Based on ArcView3.3 and ClTYgreen 5.0 model, some ecological benefits including carbon storage, carbon sequestration, air pollutants removal, oxygen release by the green spaces in the built-up area of Kunming, i. e. , Guandu District, Panlong District, Wuhua District and Xishan District was evaluated by applying large-scale regional analysis methodology and with the help of the QuickBird image, and the ecological benefit values were eventually converted into economic value. The analysis results showed that the eco-benefits generated by the green spaces in the built-up urban areas of Kunming in the year of 2008 were as follows： the total carbon storage by the green-spaces was 7 889 200 tons, whereas the annual carbon sequestration in 2008 was 60 400 tons, equivalent to economic value as RMB ￥95. 394 8 billion. The yearly air pollutants removal quantity was 2 398. 864 tons, with economic value of RMB ￥ 2 767.45 million. The yearly oxygen release quantity was 60 400 tons, with economic value of RMB ￥5 945.90 million.
