摘　　要：简要介绍了材料大气腐蚀经济损失的估算方法,并以2002年为基准年,选择了重庆市主城中心的6个功能区作为代表性区域,运用腐蚀破坏剂量响应函数和使用寿命计算公式对锌材料的腐蚀经济损失进行了定量估算。结果表明,由大气污染腐蚀破坏锌材料造成的年直接经济损失约为4061．7万元,约为同期GDP的0．1%。其中,干沉降对经济损失总量的贡献率在71%～99%之间,均值为92%。The calculation method for the economic loss caused by material corrosion was introduced. Six urban areas of Chongqing were selected as a case study for the economic loss estimation of corrosion damage on the base of 2002. By using the doseresponse functions and life functions, the economic loss of zinc corrosion was quantified, The results showed that economic loss of zinc corrosion is about 40.6 million Yuan per year, which accounts for about 0.1 percent of contemporary GDP. The contribution of eco- nomic loss caused by dry deposition to the total loss is in a range of 71%～99% , with a mean value of 92%.
