以2005～2010年粤港珠三角空气质量等级嘲格化数据为基础，基于回归分析和标准差加权修正的方法，探索性地建立珠三角空气质量评价方法。该方法综合考虑了年度空气质量变化和年度问变化趋势。利用该方法对珠三角12月份空气质量进行综合评价，结果表明：12月份评价高值中心位于佛山、中山、广卅l南部及东莞等地交界处，空气质量较差：惠州、深圳、香港及广州的从化、花都等地，空气质量评价等级为优良水平。分别用回归值、平均值跟评价值作对比以检验评价方法，结果表明，该方法所划分的评价分区与RAQI值实际情况相匹配，能基本客观地反映珠江三角洲的空气质量现状。%Based on the grid air quality levels data from 2005 to 2010 in the Pearl River Delta, regression and standard deviation weighted correction were used to evaluate and classify the air quality of PRD. The method consider the change of annual air quality, and the trend from 2006 to 2010.This method was used to evaluate the air quality of November from 2006 to 2010 in PRD. The results indicate that the high center of level of air quality located in Foshan, Zhongshan, south of Guangzhou and Dongguan. The cleanest areas were Huizhou, Shenzhen, Hongkong, Conghua and Huadu in Guangzhou, and the air quality was good in these areas. Regression values and average were compared with the value from the evaluate method. The results shows that evaluation partition of this method is match the RAQI value. The evaluate method objectively reflect the situation of air quality in PRD.
