摘　　要：目前我国大中小型城市的重金属污染情况都较为严重,其中本文将以金昌市为例,利用收集到的2014年到2016年的金昌城市PM10数值变化和铜、铬、铅、锌、砷这五项重金属污染特征进行分析。研究在这四年的当中,城市的污染水平和重金属污染元素的变化特征。并且对这四年间不同季节下的金昌污染环境进行数据收集和分析,研究季节对污染产生的影响效果。最后利用化学手段研究出人为因素是目前金昌重金属污染的主要来源,其中砷元素污染最为严重需要多加重视。At present, the heavy metal pollution situation is more serious in small and medium-sized cities of China. This article will take Jinchang city as an example, to analyze the data, characteristics of heavy metal pollution and PM10 numerical changes in copper, chromium, lead, zinc, and arsenic, which were collected from 2014 to 2015 in this city. This article refers to the pollution levels and the characteristics of heavy metal pollution elements during these four years in Jinchang. In the meauwhile, the studies on the effect of seasonal pollution have been done by collecting and analyzing the data of the pollution in Jinchang in different seasons in these four years. At last, with chemical methods, the researcher can draw a conclusion that the main source of heavy metal pollution in Jinchang mainly comes from human factors, anaong which arsenic pollution is the nlo~t serious.
