摘 要:本文以西安市为例,借助国内外城市化及大气污染方面的研究成果,应用西安市近20年的人口、经济城市化与大气污染数据,建立城市化与大气环境污染的互动关系模型,再运用熵值法计算模型各指标的权重系数,通过分析发现西安市城市化与大气污染之间关系拟合曲线呈现特殊的"N"型结构,总结了产业结构、城市化水平和大气污染三者的相关关系。并针对近两年爆发的雾霾等严重大气污染情况,进行阶段性的分析,指出能源消耗结构,机动车尾气排放和城市扩张性建筑扬尘,可能是导致近两年大气污染的主要原因,并给予科学建议。This paper takes Xi'an as an example,calculates the comprehensive index of each indicator by using entropy evaluation method with the aid of the research results on urbanization and atmospheric pollution at home and abroad and the data on the population,economic urbanization and atmospheric pollution of Xi'an city for 20 years. It builds the model on the relationship between urbanization and atmospheric environment pollution,describes the correlation relationship among industrial structure,urbanization level and atmospheric pollution and draws the conclusion that the relationship imitation curve between the urbanization and atmospheric pollution of Xi'an city has the special N-shaped structure. It also conducts periodical analysis on the serious atmospheric pollution events like haze that broke out in recent two years and points out that the main reasons that caused the atmospheric pollution in recent two years may be the structure of energy resource consumption,the tail gas emission of vehicles and the urban expansive building dust and gives scientific suggestions.
