| 摘要: |
| 通过测试，找出柳州市主城区吸收SO2、NO2能力强的植物，为今后城市生态修复和功能型园林绿化提供素材。以广西柳州市主城区内61种绿化植物为对象，采用HNO3-HClO4、H2SO4-H2O2消煮法，对其叶片的全硫、全氮含量进行测定。结果表明，所选61种绿化植物的全硫含量为0.024%-0.711%，全氮含量为0.007%-0.207%。根据硫含量，可将61种绿化植物分为3个等级，其中一级（≥ 0.55%）有1个种，二级（0.15%-0.55%）26个种，三级（≤ 0.15%）34个种。根据全氮含量，可将61种绿化植物分为3个等级，其中一级（≥ 0.14%）有10个种，二级（0.06%-0.14%）38个种，三级（≤ 0.06%）13个种。61种绿化植物全硫、全氮含量均较高的为文殊兰、洋紫荆、秋枫、合果芋、鸢尾、荷花玉兰、朱槿、红花羊蹄甲、木槿、针葵、冷水花、红叶李、鸡冠刺桐、吊钟、吊竹梅、紫色梅、山杜英、银海枣、毛杜鹃，这些植物吸收SO2、NO2能力强，在治理城市空气污染方面具有较好的应用前景。 |

| Abstract: |
| Through the test, plants with strong ability to absorb SO2 and NO2 in the main urban district of Liuzhou City were found out to provide materials for future urban ecological restoration and functional landscaping. Taking 61 species of green plants in the main urban district of Liuzhou City, Guangxi as the object, the sulfur and nitrogen content of their leaves were determined by the HNO3-HClO4 and H2SO4-H2O2 digestion method. The results show that the sulfur content of the selected 61 species of green plants was between 0.024% and 0.711%, and the nitrogen content was between 0.007% and 0.207%. According to the content of sulfur, the 61 kinds of green plants can be divided into 3 levels, of which there are 1 species at the first level (≥ 0.55%), 26 species at the second level (0.15%-0.55%), and 34 species at the third level (≤ 0.15%). According to the content of nitrogen, 61 species of green plants can be divided into 3 levels, among which there are 10 species at the first level (≥ 0.14%), 38 species at the second level (0.06%-0.14%), and 13 at the third level (≤ 0.06%). Among the 61 species of green plants, the plants below have strong ability in absorbing SO2 and NO2:Crinum asiaticum, Bauhinia variegata, Bischofia javanica, Syngonium podophyllum, Iris tectorum, Magnolia grandiflora, Hibiscus rosa-sinensis, Bauhinia blakeana, Hibiscus syriacus, Phoenix roebelenii, Pilea notata, Prunus cerasifera Ehrhar f, Erythrina crista-galli, Ibiscus schizopetalus, Tradescantia zebrine Bosse, Lantana camara, Elaeocarpus sylvestris(Lour.), Phoenix sylvestris and Rhododendron pulchrum Sweet, which have good application prospect in the treatment of urban air pollution. |
