| 摘 要： | 对西安市近10年空气污染指数(API)进行研究分析,结果显示西安市大气环境质量正向良好的趋势发展。利用最小二乘法拟合三次曲线揭示出西安市年内空气污染呈现出"污染-良好-污染"的周期性变化规律。大气污染与自然气象因素的相关性分析显示,西安市大气污染与温度、降水量有显著的负相关关系,与气压有显著的正相关关系。通过变异系数法进一步分析得出能源结构调整和节能减排是促使西安市大气环境质量改善的主要因素。 |

| Abstract: | The air pollution index(API) of Xi'an city in last nearly 10 years was researched and analyzed.The results showed that PM10 was the main pollutant but the quality of atmospheric environment in Xi'an was developing to a good trend.Using least square method to simulate cubic curve,the result revealed that yearly air pollution in Xi'an had the periodic changeable law of "pollution-good-pollution".The correlation analysis between atmospheric pollution and natural weather factors showed that air pollution had a significantly negative correlation with temperature and precipitation,and had a significantly positive correlation with air pressure.Coefficient of variation method showed that the major factors of improving air quality in Xi'an city were the adjustment of energy structure and saving of the energy. |
