摘　　要：以温州市区为研究区域,采用野外样方调查和实验室模拟相结合方法,研究常见绿化树种固碳能力和VOC的排放量及两者的相关性。结果表明:从单位土地面积日均固碳能力和VOC排放量上来看,灌木的VOC排放量相对较低且固碳能力较强。从整株水平上,固碳能力较好的树种VOC排放量也相对较高。植物固碳能力和VOC排放量具有种特异性,单位土地面积水平上固碳量高且VOC排放量较小的树种有:山茶、石楠、海桐、十大功劳、红花檵木、蚊母树、夹竹桃、白兰花、桂花和香叶树,可以作为城市绿化的推荐树种。Carbon fixation capacity and volatile organic compounds （VOC） emissions of common green plant species in Wenzhou city were investigated by using the methods of field sampling and laboratory simulation. The results show that the shrubs had lower VOC emissions but higher carbon fixation compared to tree species in per unit area; Taking individual plant as a unit, however, the species with higher carbon fixation had higher VOC emissions; There was a species specificity in carbon fixation and VOC emissions among the common greening trees; Measuring in per unit area, the species with higher carbon fixation and low VOC emissions were Camellia japonica, Photinia serrulata, Pittosporum tobira, Mahonia fortunei, Loropetalum chinense var. rubrum, Distylium racemosum, Nerium oleander, Michelia alba and Lindera communis. These species could be recommended for urban virescence.
