摘　　要：依据汉中市环保局自动监测系统对汉中市区大气环境质量的监测数据,统计分析了汉中市区大气气溶胶的分布特征及形成原因,并以2008—2009年的监测数据为例给出了汉中市区3个监测点监测的PM10和含S型气溶胶粒子质量平均浓度的月分布曲线,结果显示:市区中心PM10月平均质量浓度最大,离市区中心越远,PM10月平均质量浓度越小;一年当中汉中市区的大气环境质量1月和12月最差,6—8月最好。Using the monitoring data of the environmental air quality of Hanzhong urban by automatic monitoring system of Hanzhong Environmental Protection Bureau, the distribution characteristics and formation reason of atmospheric aerosol in Hanzhong urban are statistically analyzed, and the month distribution curve of PMlo and with S type of aerosol particle mass average concentration of three monitoring sites in Hanzhong urban are given based on monitoring data of 2008 and 2009 year. The results show that the monthly mean mass con- centration of PMIo is maximum in urban center, and the farther from the urban,the smaller the monthly mean mass concentration of PM10, and that the environmental air quality of Hanzhong urban is the worst in January and December, and the best from June to Augest.
