摘　　要：通过卫星遥感图片解译和实地调查的技术路线,对重庆市主城建成区室外建筑材料暴露存量进行了调查,同时核算了大气中SO2和酸雨两种污染因子对建筑材料造成的直接经济损失.结果表明,2004年,重庆市主城建成区建筑材料暴露总存量为18 546.9 m2,其中陶瓷暴露存量最大,占总暴露量的49.30%;大气污染对该区域建筑材料腐蚀的经济损失价值量为8 211.80万元,对铝的腐蚀造成的经济损失最大,占总损失值的50.1%.By translating the remote sensing pictures and site visiting,the stock of building materials exposed outdoors in the main urban area of Chongqing was surveyed and the direct economic loss caused by SO2 and acid rain was estimated.The results showed that the total exposed material stock was as high as 18 546.9 square meters in 2004,of which 49.30% was ceramics.The economic loss of building material corroded by polluted air was 8.211 8 million yuan and the aluminum corrosion brought the largest loss,accounting for 50.1% of the total.
