| 摘 要： | 对常德市太阳山大气成分站GRIMM-180颗粒物监测仪2006年9～10月PM10质量浓度资料进行分析，结果得出非降水天气下质量浓度日变化呈双峰分布。主要影响因子为人类生产活动直接产生和排放的气溶胶以及影响气溶胶扩散的气象条件大气湍流，非降水有雾天气质量浓度明显比无雾天气偏高；降水天气过程对大气中气溶胶有明显湿清除作用；对比常德市环境监测站PM10观测采样资料，两者具有很高的相关性，常德市环境监测站的PM10浓度要略高于太阳山大气成分站，说明太阳山受到人为影响更弱一些，具有更加充分的区域代表性。

| Abstract: | The mass concentration data of PM10 at air composition station of Taiyang Mountain in Changde in September and October of 2006 by using GRIMM-180 particulate matter monitoring apparatus were analyzed.The results showed that the daily changes of mass concentration under the non-rainfall conditions showed the double-peak distribution.The main influencing factors included the aerosol directly produced and exhausted from the human production and living and the atmospheric turbulence of meteorologic conditions t... |
