摘　　要：针对大比例尺城市图对建筑物进行质量评估,分析了建筑物和街道之间存在相互影响、互补共存的动态关联关系及街道骨架线区别于一般骨架线的特殊性,提出借助街道进行建筑物几何质量评估的新思想,用骨架线替代街道,进一步演化为基于降维处理的质量评估新体系;给出了依据街道骨架线对建筑物轮廓化简、合并、位移和冲突处理等4个方面进行几何评估的方法、评估步骤和6个操作准则。Quality assessment to city buildings using large-scale city map is studied in this paper. The dynamic relationship between city buildings and streets is analyzed, which is that buildings and streets influence each other and join together to fill the whole area. And the skeleton-line created from area streets is provided with more particularity than others. Then, a new idea of assessing city building＇ s geometry quality by street is put forward. Furthermore, instead of street, skeleton-line is used to assess the building＇ s quality, and is evolved into the quality assessment system based on reducing-dimension processing. Particular methods, steps and six operation rules of quality assessment by street skeleton-line to building contour simplification, building mergence, building displacement, and conflicting processing are expatiated.
