安徽马鞍山市是一座新兴的产业结构单一的钢铁工业城市,城市空气污染物主要来源于钢铁工业的矿石冶炼、煤炭焦化及工业锅炉等点源污染。以该市近年来(1991～2001)空气环境例行监测数据为依据,从城市能源结构、气象特征、空气污染物浓度变化规律、各污染物污染状况及周边大城市之影响等方面对该市空气环境质量进行综合分析、评价。结果表明,对于产业结构单一钢铁工业小城市来说,其空气污染主要来自于工业点源污染,点源是空气污染控制、治理的重点。

Ma'anshan is a newer city in Anhui province, which has a singular structure-iron & steel industry. The pollutants in the city are point source pollution, which mainly comes from ore melting, coal coking and coal burning. Based on the data of total SO_2 emission, the concentration of pollutants, the frequency of acid rain and concentration of sulfation etc. , the paper analyses the variable characteristics of pollutants concentration in the city. As to the main air pollutants are derived from point source pollution, we should emphasis on the control and treatment of it. It is concluded that the air pollution in Ma'anshan city not only connecting with itself, but also having relationship with its neighbor city Nanjing.
