摘　　要：目的：分析评价眉县主要区域大气环境质量现状，并提出控制措施。方法：依据眉县人口密集的首善镇和工业密集的常兴镇2004～2005年各月份大气环境监测资料，并选取汤峪镇作为空气质量作对照区对该县的大气环境质量状况进行了分析评价。结果：结果表明造成该地区大气污染的首要污染物是可吸入颗粒物PM10，其次为SO2，NO2污染轻微；在一年中，冬春季污染强，其它季节较弱。结论：分析可知锅炉燃煤和扬尘是造成大气污染的主要原因，因此要提高该地区大气环境质量，必须改善能源结构，改变落后的燃煤方式，发展集中供热，加强污染项目环境管理，增加绿地覆盖面积。Aim To analyze and study the air quality and control measures of Meixian County, Shaanxi,China. Methods According to the average monitoring results of the air environment at Shoushan Town （impacted area） and Changxing Town （industrial area） in Meixian every month in 2004 and 2005, and compare to tour area at Tangyu in Meixian, Tangyu is referred to as an excellent district, the air quality of Meixian is evaluated. Results The results shown that PM10 is the main pollution of the area and it make the air medium pollution, SO2 is another important pollution and NO2 pollution slightly. In a year, air pollution is very serious in winter and spring. Conclusion In order to improve the air environment, it is necessary to make urban plan, change the ener- gy structure and adopt the hydro techniques of cleaning sulphur away, and choose the suitable category to increase the coverage of vegetation.
