摘　　要：以QuickBird卫星影像数据为基础数据源,结合RS、GIS技术,采用计算机监督分类结合目视解译获取城市绿地类型信息的方法,调查北碚城区绿地状况,并利用模糊评判模型对北碚城区不同类型绿地的生态效益进行评分。结果表明,北碚城区绿地覆盖率为37.34%,附属绿地、其他绿地的生态效益最高,生产绿地次之,公园绿地和防护绿地最低。With satellite images data as the underlying data source,and by using the RS and GIS technology,the computer supervised classification and visual interpretation were adopted to obtain the urban green space information and investigate the urban green space status of Beibei,the fuzzy evaluation model was used to evaluate the ecological benefit of different types of green space in urban Beibei.Results showed that the green space coverage in urban Beibei was 37.34%,the ecological benefits of the attached green space and other green lands were the highest,then followed by productive green land,at last park green land and protective greenland.
