摘　　要：以新建建筑产生的固体废弃物为研究对象,将改进的材料跟踪法、基于R语言的算法和数据挖掘技术相结合,合理规避了传统方法中数据提取粗糙与数据获取主观性强的问题.同时,通过现场调研获取全国不同区域新建居住建筑的基础数据,进行实证分析.结果表明,施工现场废弃混凝土、废弃钢筋、废弃砌块产生率的典型值分别为3.28%,2.88%,3.33%,代表区间分别为(0.6144%,5.9456%),(0.622%,5.138%),(0.6103%,6.02%).与已有数据对比发现,我国新建建筑中固体废弃物产生率高于定额损耗率,固废管理水平存在区域性差异,呈"沿海高、内地低"的态势,且整体减量化水平亟待提高.An innovative approach was proposed, in which integrated the improved material tracking method, R-based algorithms with data-mining techniques to overcome the problem of rough and subjective data-obtaining in traditional methods. Then, an empirical analysis on the OSW data was collected from new residential buildings located at multiple regions cross China. The results showed that for the common wastes: concreate, steel, and masonry, the typical waste generation rates were 3.28%, 2.88%, and 3.33%, and the representative intervals were from 0.6144% to 5.9456%, 0.622% to 5.138%, 0.6103% to 6.02%, respectively. Comparing with the previous data, the rate of OSW's generation was higher than that of normal loss in new constructions. Furthermore, the regional differences in solid waste management in which the management performance in coastal cities was better than that in inland cities.
