摘　　要：文章以辽宁省大连市中心城区为例,基于卫星遥感影像、百度街景数据及图像语义分析和线上调查,提取街道植被覆盖率、绿视率及绿化配置数据,进行绿化质量测度与评价。结果显示:(1)研究区域整体的街道绿化质量一般,植被覆盖率均值为32.84%,绿视率均值为22.40%,绿化配置简单占比61.53%;(2)商业型街区的3项绿化指标表现最差,景观休闲型街区的街道绿视率与绿化配置水平最高;(3)行道树冠幅、街道和路幅宽度、乔灌草的搭配,以及街旁绿地的布置均是影响街道绿化质量的因素。Taking the central urban area of Dalian as an example,based on satellite remote sensing images,Baidu Street View data,image semantic analysis and online survey,this paper extracted street vegetation coverage rate,green view index and greenery configuration data to measure and evaluate green quality.The results showed as follows:The overall street greening quality in the study area was general.The average vegetation coverage rate was 32.84%,the average green view index was 22.40%,and the simple green configuration accounted for 61.53%.②Commercial blocks had the worst performance in three greenery indicators,while landscape leisure blocks had the highest street green view index and greenery configuration level.@The factors affecting the quality of street greenery include crown width of sidewalk trees,street and road width,collocation of trees,shrubs and grasses,and arrangement of roadsidegreen space.
