英文摘要	为了研究贵阳建筑扬尘的环境影响,根据对建筑和市政施工工程的调查,估算了贵阳市区2002年建筑扬尘的PM_(10)排放量,并利用CALPUFF模型模拟了建筑扬尘对PM_(10)浓度的贡献,分析了其季节变化及影响因素.结果表明,2002年贵阳城区建筑扬尘的PM_(10)排放量为416 t,占PM_(10)排放总量的4%.建筑扬尘对贵阳市区较大范围内的PM_(10)浓度水平均有影响,对整个城区PM_(10)的年均浓度贡献接近12%.受施工强度以及风场和降水等气象因素作用,建筑扬尘排放的影响体现出明显的季节变化.; To study influences of construction fugitive in Guiyang, construction fugitive PM_(10) emission in 2002 was estimated based on an extensive survey of construction activities in Guiyang. The contribution of construction fugitive dust to ambient PM_(10) was simulated using the CALPUFF model, and the seasonal variation as well as influencing factors were addressed. The results show that fugitive PM_(10) emission from construction activities was up to 416 tons, accounting for 4% of all PM_(10) source emissions in the urban area of Guiyang. Construction fugitive dust showed great impact on the ambient PM_(10) level in Guiyang, and contributed 12% to the annual mean concentration of PM_(10) over the urban area. Significant seasonal variation of the contribution of construction fugitive dust was found due to the change of construction activities and meteorological conditions (wind and precipitation).; 联合国开发计划署(UNDP)项目; 科技部科研项目; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 0; 2; 258-264; 46
