【摘要】 随着社会经济与城市化的快速发展,大气污染日益加剧,空气质量问题已引起人们的密切关注和重视。本文选取长三角地区典型三大城市十年空气质量相关数据,运用系统聚类方法,对三大城市空气质量进行对比分析,结果表明:上海的空气质量相对杭州和南京较好,南京市的PM₁₀及NO₂浓度均有相对较高的现象,而杭州PM₁₀浓度在2003至2008年相对偏高。根据研究结果,提出控制工业废气排放、调整能源结构、开发清洁能源、加强汽车尾气排放控制、淘汰老旧机动车等政策建议。更多还原

【Abstract】 With the rapid development of social economy and urbanization,air pollution is becoming more and more intensified,and the air quality has caused people to pay close attention and attention. This paper selected air quality data of ten years of the Yangtze River Delta city. By using system clustering method,it carries on the contrast analysis of the three urban air quality. The results showed that the air quality in Shanghai was better than Hangzhou and Nanjing,PM₁₀ and NO₂concentrations in Nanjing were relatively higher,and PM₁₀ concentration in Hangzhou in 2003- 2008 was relatively high. According to the research results,it puts forward suggestions such as industrial waste gas emission control,adjusting the energy structure,the development of clean energy,improve the control of automobile exhaust emissions,to phase out old vehicles.更多还原
