中文摘要 从区域大气环境管理的角度出发，提出大气环境分区管理的理念.以广东省地区为例，利用空气质量数值模拟和卫星遥感反演分析相结合的方法，从气象要素模拟场、浓度要素模拟场和卫星图像解译中筛选出关键因子，形成大气环境管理分区指标体系，在此基础上，利用层次聚类分析法将广东省划分为严格控制区、持续改善区和协调发展区这3种大气环境管理分区类型.结果表明，广东省大气环境管理严格控制区、持续改善区和协调发展区分别占16.3%、28.0%和55.7%.严格控制区在珠三角、粤东、粤西和粤北所占的比例分别为27.9%、19.3%、4.4%和12.5%，区域内应实施最严格的大气环境管理政策以推动空气质量改善；持续改善区在珠三角、粤东、粤西和粤北所占的比例分别为34.4%、15.8%、7.8和34.5%，区域内应实施相对严格的大气环境管理政策以保障持续稳定达标；协调发展区在珠三角、粤东、粤西和粤北所占的比例分别为37.7%、64.9%、87.8%和53.0%，区域内应实施较为宽松的大气环境管理政策以保障相对良好的空气质量.总体而言，广东省大气环境管理压力主要集中在珠三角地区，粤北、粤东地区次之，粤西地区大气环境管理压力最小. 英文摘要 To meet the requirements of regional air quality management (AQM), the Air Quality Subarea Management (AQSM) system was proposed. A case study was conducted for Guangdong Province. By using the method of air quality numerical simulation and satellite remote sensing inversion analysis, the key factors were selected from the meteorological simulation field, the pollutant concentration simulation field, and the satellite image interpretation to form the index system for AQSM. On this basis, a hierarchical cluster analysis method was used to divide Guangdong Province into three types of AQSM:Strict Control Subarea, Continuous Improvement Subarea, and Coordinated Development Subarea. It was shown that the Strict Control Subarea, Continuous Improvement Subarea, and Coordinated Development Subarea in Guangdong Province covered 16.3%, 28.0%, and 55.7%, respectively. The Strict Control Subarea in the Pearl River Delta, Eastern Guangdong, Western Guangdong, and Northern Guangdong accounted for 27.9%, 19.3%, 4.4%, and 12.5%, respectively, and the subarea should implement the most stringent AQM policies to promote air quality improvement. The Continuous Improvement Subarea in the Pearl River Delta, Eastern Guangdong, Western Guangdong, and Northern Guangdong accounted for 34.4%, 15.8%, 7.8%, and 34.5%, respectively, and the subarea should implement relatively strict AQM policies to ensure sustained and stable standards. The Coordinated Development Subarea in the Pearl River Delta, Eastern Guangdong, Western Guangdong, and Northern Guangdong accounted for 37.7%, 64.9%, 87.8%, and 53.0%, respectively, and the subarea could implement more liberal AQM policies to ensure relatively good air quality. In general, the strict AQM policies in Guangdong Province should be mainly concentrated in the Pearl River Delta region, followed by Northern Guangdong, Eastern Guangdong, and Western Guangdong in order.
