| 摘 要： | 根据天津市2003—2007年灰霾日的污染物浓度和气象资料,应用主成分分析方法得出影响灰霾的5个主要因子(SO2、相对湿度、总云量、PM10和风速)。对相对湿度、总云量和风速3个气象因子的历史资料进行频数统计分析,并建立了各气象因子的等级划分标准。利用灰色聚类法构建了天津市灰霾评价的等级指标体系,灰霾等级划分结果表明,天津市轻度灰霾和重度灰霾出现天数相对较少,均以中度灰霾为主;轻度灰霾大多出现在春季和夏季;重度灰霾主要出现在冬季,春季出现的比例最小;综合评价分析,冬季灰霾污染程度最为严重。 |

| Abstract: | Based on the history data of diurnal contaminations and meteorological conditions from 2003 to 2007 in Tianjin, we arrived at the conclusion that the main factors affecting the haze were SO2, cloudage, relative humidity, PM10 and weed speed through the method of component analysis. According to the statistical distribution of meteorological factors frequency, the haze index-classified system for Tianjin City atmosphere was established, and the haze classifies in Tianjin City was achieved by using grey clust... |
