| 摘 要： | 依据灰色系统理论，采用灰色变权聚类方法，根据国家环境质量标准，对南京市城区近两年的空气质量进行评估。空气质量评估采用的指标包含二氧化硫、二氧化氮以及可吸入颗粒物的浓度，并对评估结果进行了分析和讨论。结果表明，南京市城区空气环境质量呈退化的趋势，尤其是经济繁华的鼓楼区以及交通拥挤的下关区，两年内空气质量明显下降。

| Abstract: | According to the national standard of environment quality, we analyzed and assessed the atmospheric quality in the urban area of Nanjing in the recent two years. The concentration of SO2 ,NO2 ,and PM10 were chosed as assessing indicators and grey clustering method was used for evaluation. The studying area was divided into 6 administration districts. The result shows that atmospheric environment quality degenerated across the whole region. Among the 6 districts,Gulou District and Xiaguan District had the fastest declining speed due to rapidly developed economy and heavy traffic burden. |
