摘　　要：探讨了钢铁厂绿化植栽对空气中微粒物质及SO2的净化效果，选取19种常见绿化树种进行评估。在钢铁厂高炉作业区及污染较低的学校区分别置放试验树种，试验共为期16个月，试验结束后，通过叶片累积微粒物质含量分析其拦截粒状物效能；而通过叶片内含硫量分析推估对空气中SO2的净化效益。结果显示，对大气中微粒净化效能以兰屿肉豆蔻最佳，净化量为29．1g／m^2；其次为棱果榕与海芒果，净化量分别24.2、17．4g／m^2。试验树种吸收大气中SO2以竹柏、棱果榕及兰屿肉豆蔻较佳，单位质量叶片去除SO2量分别为0．92、0．9、0．8mg。The aim of this research was to study the purifying efficiency of plants to particles and sulfur dioxide in the steel industry air. There were 19 common greening trees were put around the blast furnace of steel mill and low air pollution school area, respectively. The total exposure period was 16 months. At the end of the experiment,the particles on leaves and sulfur content in blades were measured for the purifying efficiency assessment. The results showed that the highest particles purifying capability among all tested trees was Myristica cagayanensis, the next were Ficus septica and Cerbera rnanghas. The purify capacities of particles were 29.1, 24.2 and 17.4 g/m^2,respectively. The highest purifying efficiency for sulfur dioxide were Decussocarpus nagi, Ficus septica,and Myristica cagayanensis with the sulfur dioxide purify capacities 0.92,0.9,0.8 mg/g respectively.
