In this paper, based on the field test and long-term monitoring of indoor air quality ( IAQ ) of newly decorated residences in Shenzhen, indoor air pollution status and variation rules due to decoration were concluded. Survey results indicated that the pollution level of Shenzhen newly decorated residences was coincide with other cities, the concentrations of formaldehyde and TVOC were over the limited rate of more than 60% . Furthermore,it was found that furniture was the most important chemical pollution source, and because of its high-density use, the pollutant conditions in bedroom and kids' room were more serious than others. Besides, decoration pollution declined rapidly but had a long duration, different pollutants had different decline duration and benzene pollution decreased more rapidly than formaldehyde.%本文通过对深圳市新装修住宅室内空气质量进行现场测试和长期监测,总结了此类住宅的室内空气污染现状,对装饰装修所带来的室内空气污染规律进行了分析.调研结果显示,深圳市装修污染水平基本与全国平均水平一致,甲醛和TVOC超标率均高于60％；家具是住宅室内空气化学污染最主要的污染源,且由于其使用密度高,卧室和儿童房等功能房间污染程度最为严重；化学污染在装修后初期能够快速下降,但后期衰减缓慢,持续时间长；不同的污染物衰减过程有所差异,苯系物污染相比于甲醛污染衰减的更快一些.
