摘要
本文利用焦作城区大气降尘实测数据,应用地理信息系统(GIS)技术对其空间污染状况进行了分区评价,并根据分区原则建立了降尘动态变化分类系统,在此基础上,对1994、1995年城区降尘污染分区图进行复合处理,得到1994～1995年城区降尘污染,得到1994～1995年间焦作城区降尘污染类型动态转化数据信息,并以此为依据对降尘污染的动态变化规律进行了深入的分析。
This paper applies the Geography Information System (GIS) technology to study the pollu tion state of atmospheric dustfall in Jiaozuo city of Henan province. Through buiding the classified system, the changing information of atmospheric dustfall pollution in this area is earned by apply ing ARC/INFO software to dealing with the polluted maps of 1994 and 1995. And then,a deeply analysis on the developing regularity of atmospheric dustfall in this city is made.
