摘　　要：用Daniel检验法对2001—2010年兰州市大气、水、噪声和固体废物污染的变化趋势进行了定量分析.结果表明,治污措施起到了明显的作用,大气污染状况有所改善,优良天数比例显著增多,SO2,PM10年均浓度显著减小.粉尘排放量和沙尘天气次数是PM10污染的主因,相关系数分别为0.836和0.816.85.69%的排放比重、仅40%的处理率和较差的水质表明生活污水已成为水污染的主因.显著好转的区域噪声仍属轻度污染,治理重点是生活方面;交通噪声有加重趋势.工业固体废物的治理无实质性进展,剩余量的大量贮存存在着污染隐患.The Daniel test method is used to do quantitative analysis to the change of the pollution of air,water,noise,solid waste in Lanzhou City from 2001 to 2010,the result is that the effect of measure is obvious and air pollution is better：fine days are more and more,the concentration of SO2 and PM10 have reduced.Dust emissions and dust times are the main cause of PM10 pollution,their correlation coefficient are 0.836 and 0.816.85.69% of emissions proportion,40% of processing rate and poor water quality show that sanitary sewage is the main cause of water pollution.The obviously improved regional noise still belongs to light pollution,the key management is in living aspect;the trend of traffic noise will be worse.The management of industrial solid have little improvement,its surplus largely stored is a hidden danger.
