为了解城市绿化常见树种枫香释放的挥发性有机物种类、月动态及日动态变化，于2010年5—11月，采用动态顶空吸附法和热脱附－气相色谱－质谱联用法（TCT －GC／MS），在南京紫金山国家森林公园灵谷寺景区，对枫香日释放的挥发性有机物进行测定分析，探讨释放量与环境因子的关系。结果表明：枫香花期共释放出43种挥发性有机物，以烯类化合物为主，其量占化合物总含量的94.19％，主要是柠檬烯、β－蒎烯和α－蒎烯。烯类化合物月平均释放量占挥发性有机物总释放量的87.04％，8月最高，其季节规律是夏季＞秋季＞春季。烯类化合物日变化是先升后降，其变化趋势与温度的日变化呈正相关。

In order to understand the types of volatile organic compounds as well as common monthly and daily dynamic changes of urban green trees sweet gums (Liquidambar formosan)released,we used a dynamic headspace adsorption and thermal desorption-gas chromatography-mass spectrometry (TCT-GC /MS),to investigate VOCs re-leased of sweet gums in Spirit Valley area on Purple Mountain National Forest Park in October,and discussed the relationship between emissions and environmental factors.The results showed that the flowering sweet gums totally released 43 kinds of VOCs.With vinyl compounds based,accounting for 94.19% of the compound content,they were mainly limonene,β-pinene and α-pinene.Liquidambar formosana released mainly vinyl compounds monthly and the average amounted to 87.04%,the highest in August.The release amount of vinyl and aldehydes were sum-mer >autumn >spring.Vinyl compounds increased firstly and then decreased.Vinyl compounds diurnal variation and temperature trend were positively correlated.
