【摘要】 通过统计大量实测数据,对北京市建筑工地施工扬尘大气污染指标DF与TSP的相关性进行了研究.结果表明,建筑施工扬尘所产生的DF与TSP有较好的线性关系,建筑工地边界处DF与TSP的关系可以用cTSP=11.6×cDF表示.监测点与污染源的距离对相关系数影响较大,相关系数与距离成正比例;施工阶段对相关系数影响较小.更多还原

【Abstract】 This paper studied the correlation between dust fall and TSP from construction sites in Beijing by statistically analyzing a large number of field measurement data.The results show that there are better linear correlations between dust fall and TSP from construction fugitive dust,and the correlation between dust fall and TSP at construction sites’ boundary can be expressed by the function:c_TSP=11.6×c_DF.The distance between monitoring site and fugitive dust source performs a considerable influence on the correlation coefficients that is proportional to the distance.However,construction phases’ influence is lesser.更多还原
