摘要
2004年起，中国气象局在北京上甸子、浙江临安和黑龙江龙凤山区域本底站先后开展了包括大气气溶胶、反应性气体等在内的业务观测。2006年初中国气象局充分利用已有站网，结合国家大气成分本底台站的建设以及大气成分预报业务的发展急需，在全国14个关键区域布设了包括7个大气本底台站在内的30个大气成分观测站，形成了全国大气成分观测网（图1）。
The operation observation of aerosols, reactive gases, etc., has been conducted at atmospheric background stations at Lin＇an in Zhejiang Province, Shangdianzi in Beijing and Longfengshan in Heilongjiang Province since 2004. The nationwide atmospheric composition observation network consisting of 30 observing stations, 7 background stations over 14 key observation areas was established in the early 2006 by the China Meteorological Administration based on the existing observation stations according to the needs of national atmospheric composition service development （Fig. 1）.
