摘要
当前,我国的大气环境污染形势越来越严峻,由于工业发展、生活环境不同,各城市的废气排放量和废气来源存在一定差异。为了探讨不同城市废气排放的特点,利用SPSS软件选取工业废气的三项指标进行聚类分析,可以依据各城市工业废气排放的严重情况将31个城市分为三类等级。选取工业废气和生活废气六项指标进行因子分析,综合评分最高的城市有重庆、哈尔滨、长春和武汉,说明这4个城市的综合废气排放情况最为严重。对不同排放类型的城市提供了相应的减排建议。
At present,the situation of atmospheric environmental pollution in China is becoming more and more severe.Due to industrial development and different living environments,there are certain differences in the emission volume and source of waste gas in various cities.In order to explore the characteristics of waste gas emission in different cities,using SPSS software to select three indicators of industrial waste gas for cluster analysis can divide 31 cities into three categories based on the severity of industrial waste gas emission in each city.Selecting six indicators of industrial waste gas and domestic waste gas for factor analysis,the cities with the highest comprehensive scores are Chongqing,Harbin,Changchun and Wuhan,indicating that the comprehensive waste gas emission situation in these four cities is the most serious.Recommendations for emission reduction are provided for cities with different emission types.
