| 中文摘要: |
| 2014年7月和2015年1月分别系统监测淮南市6个功能区夏、冬季大气颗粒物（TSP、PM10、PM2.5）质量浓度并分析其时空分布特征。结果表明：采矿区和工业区污染较严重；采矿区主要受采煤、运输等人为活动的影响，工业区受工业排放影响较大，商业区主要以汽车尾气排放为主，居民区和文教区则以燃煤排放为主；夏季颗粒物浓度日变化趋势均呈现两边凸中间凹的特征，峰值分别出现在7:00和18:00，谷值出现在13:00左右，而冬季变化趋势波动较大。 |
| 英文摘要: |
| Mass concentration of TSP, PM10, PM2.5 was monitored in six functional areas including commercial area, cultural area, industrial area, residential area, mining area and control area in Huainan from July 2014 to January 2015. The results showed that: Mass concentration in mining area and industrial area were higher than that in other functional areas. Mining area was mainly affected by coal mining and transportation. Industrial area was influenced by industrial emissions. Commercial area was mainly affected by vehicle emissions, and residential area and cultural area were given priority to coal emissions. The concentration of particulate matter increased at 7:00 and 18:00 and decreased at about 13:00 in summer. The data had a large fluctuation in winter. |
