两种标准下西安市环境空气质量的定量研究

针对新旧空气质量标准差异、西安市空气质量影响因素和预测西安市未来空气质量,通过模糊综合评价、主成分分析和三次指数平滑等方法,建立模糊综合评价、主成分分析和三次指数平滑等模型,综合评价两种空气质量标准(API、AQI),分析出西安市空气质量的影响因素包括季节和能源消耗结构等以及预测出西安市未来一周空气质量为中度污染。

Study of Xi'an City Ambient Air Quality Based on the Two Standards

The paper is aimed at the difference between old and new air quality standards, the impact factors on air quality in Xi'an city and the prediction of Xi'an city future air quality. According to fuzzy comprehensive evaluation, principal component analysis and the three exponential smoothing methods, we have established fuzzy comprehensive evaluation, principal component analysis and the three exponential smoothing models. Besides we also evaluate the two kinds of air quality standard (API, AQI) comprehensively, analyze the impact of air quality in Xi'an city factors including seasonal and energy consumption structure and predict the Xi'an city next week for air quality pollution.
