| 摘 要： | 通过大气污染物浓度年均值和排放总量等指标,简要分析了沈阳市大气质量,应用生态足迹方法量化了大气污染物的综合环境压力.结果表明:过去10年间,沈阳市SO2排放总量显著下降,但CO2排放量增长迅速.以生态足迹表征的大气污染物对生态环境的综合压力主要来自二氧化碳和二氧化硫,1990~1994年二者足迹在大气污染总足迹中所占比例约为各50%;1995~2000年间,CO2足迹所占份额有所增加,但增幅不大;2000年以后增加迅速,2005年达到90%.以单位GDP的大气污染物排放量和生态足迹表征的沈阳市经济发展环境效率,在研究期有较显著的上升,说明经济系统创造单位GDP对大气质量的影响和对生态环境的压力...

| Abstract: | Based on such indices as the annual mean values of pollutant concentration in atmosphere and the total emissivity of pollutants,the air quality in Shenyang was analyzed briefly with the comprehensive environmental pressure due to air pollutants quantified by ecological footprint.The results showed that the total amount of SO2 was reduced significantly during the past 10 years.However,the total amount of CO2 emission increased rapidly.Characterized by ecological footprints,the comprehensive environmental pre... |
