摘要
大气中的酸性物质对材料的破坏是酸沉降经济损失中的重要部分。简要说明了材料损失的计算方法,并以2001年为基准年,选择了广州市作为代表性城市,运用材料损伤函数和材料使用寿命公式对建筑材料及自行车的经济损失进行了估算,使酸沉降的破坏作用达到定量化。
The damage to materials caused by acidic matter in atmosphere is the main portion of the economic lost caused by acid deposition. The computing method for the damage is introduced briefly in this paper. The target year for the calculation is 2001 and Guangzhou is selected as a case study. By using dose-response functions and life functions to calculate the damage to the building materials and bicycles, the destructive action of acid deposition is quantified.
