摘　　要：选择福州4种主要的行道树作为研究对象，比较空气污染较为严重的道路区域和相对清新的城市（郊）公园区域树种吸收S02能力的差异，进而推算出不同树种吸收SO2的价值．研究结果表明：首先不同树种叶片的吸硫强度在0．234—1．557mg·g-1间变化，不同树种差异明显，樟树吸硫强度最大，其次为芒果、榕树和洋紫荆；其次，按单株计，樟树单株年净化SO2最大，分别是芒果、榕树和洋紫荆的3．21、3．69和40．89倍．最后，采用投资替代法评估，福州市单位面积城市森林年净化SO2的经济价值达0．344元·m-2·a-1．This study selected four main street tree species of Fuzhou city as ours research objects, compare the different of absorbing sulfur ability between polluted streets and non-polluted urban parks environment, and then estimated that different tree species absorb sulfur value. The research showed that the intensity absorbing sulfur among different tree species was 0.234 - 1. 557 mg g-1. Among which, the maximum of intensity absorbing sulfur occurred in C. camphora, followed by Mangifera in- dica, F. microcarpa and Bauhinia blakeana ; C. camphora also have the maximum of annum sulfur di- oxide purification, which were 3.21,3.69 and 40.89 times as many as pa and Bauhinia blakeana; By investment substitute method, the unit green space area economic value of annual purification sulfur in Fuzhou urban forestry was estimated 0.344 yuan m-2 a-1.
