摘要
应用地理信息系统(GIS)技术分析了焦作市城区大气降尘污染状况。根据1995年城区降尘实测数据,绘制了降尘量等值线图.分析了城区降尘污染的空间分布特征,引入降尘污染指数,将降尘污染程度做了六级划分,并利用ARC/INFO软件进行图像处理,生成拓扑关系,从而对焦作城区降尘污染程度进行了分区和评价。
The geography information system (GIS) technology was applied to deal with the pollution state of atmospheric dust fall in Jiaozuo City of Henan Province. According to the actual data measured in 1995, isogram of dustfall quantities was drawn and distributional feature of the dust fall in space of the area was analysed. Based on the index of dustfall pollution, 6 kind levels of the dust fall were classified and picture treatment was made by ARC/INFO software, and from this, topological relation was generated and the space division and assessment of dust fall pollution of this area were made.
