摘　　要：利用广东省86个气象观测站1961—2013年记录霾日资料和1981—2013年统计霾日资料,采用线性趋势分析、计算气候趋势系数等统计诊断方法,分析了广东记录霾日和统计霾日的气候特征并进行比较。结果表明：广东统计霾日与记录霾日的年平均分布非常相似,但是统计霾日数比记录霾日数明显增加10-80d。广东霾分布可划分为三个区：（1）多霾区：包括珠江三角洲、北部的南雄、东南部的汕头,年统计霾日40.0-144.5d;（2）一般霾区：包括广东中部偏北的部分地区,年统计霾日20.0-39.9d;（3）少霾区：广东西南部和东部大部分地区,年统计霾日1.0-19.9d。广东年记录霾日和统计霾日均以11d（10a）的速率明显上升,1990年后显著增加,特别是2003年以来上升非常明显,2007年达到最大,但2008年以来逐年波动下降。广东年霾日数增加最明显的区域在珠三角、汕头、南雄等地。1980—2013年的广东平均年记录霾日序列与统计霾日序列的相关系数达0.78,显著相关。分析表明统计霾日比记录霾日总体上更客观合理,并对两者存在差异的原因进行了分析与讨论。Based on the recording haze days during stations in Guangdong, the climatic characteristics 1961-2013 and statistical haze days of 86 meteorological and comparison of recording and statistical haze days in Guangdong were studied by using statistical diagnostic methods, such as linear regression analysis, the computation of trend coefficients. The results indicate that the distribution of annual mean haze days for recording and statistical were quite similar, but statistical haze days were more than recording haze days from 10 to 80 d. The distribution of annual mean haze days in Guangdong can be divided into three areas ： （ 1 ） more haze regions ： including the Pearl River delta area, Nanxiong in the north and Shantou in the southeast of Guangdong, the an- nual statistical haze days were 40. 0 - 144.5 d. （2） general haze regions： including the north of middle area of Guangdong, the annual statistical haze days were 20.0 - 39.9 d. （3） less haze regions ： including the southwest area of Guangdong, the most east part of Guangdong, the annual statistical haze days were 1.0 - 19. 9 d. The annual recording and statistical hazes days in Guangdong increased obviously at a mean rate of 11 d/（ 10 a）, increased significantly since 1990, especially had rapid growth after 2003 and the top was at 2007, it decreased with fluctuation after 2008. The increasing trends of haze days of Guangdong were obvious in the Pearl River Delta area, Shantou, Nanxiong and so on. Correlation coefficient was 0. 78 between the annual mean recording hazes days and statistical hazes days during 1981-2013 in Guangdong and correlated significantly with each other, but statistical hazes days was more objective and reasonable than recording hazes days, and analysis and discussion for the cause of the two difference.
