摘　　要：采集遥感影像信息,利用最大似然分类法,分类影像信息,校正遥感影像采集的信息,建立被校正影像与参考图之间的关系。在此基础上,利用GIS技术模拟大气污染扩散,考量大气污染指标与种类,得到空气质量综合指数,以此实现区域大气污染监测。以监测PM2.5和PM10污染指标值为实验对象,实验对比结果表明,此次设计的区域大气监测方法监测到的PM2.5和PM10指标与实际值相差小,传统方法测得的值与实际值相差较大,证明此次设计的基于卫星遥感和GIS技术的区域大气污染监测方法比传统方法监测精度高,具备实际应用意义。Aiming at the low precision of traditional regional air pollution monitoring methods,a regional air pollution monitoring method based on satellite remote sensing and GIS technology is designed.This study collected remote sensing image information,used maximum likelihood classification,classified image information,corrected the information collected by remote sensing image,and established the relationship between corrected image and reference.On this basis,using GIS technology to simulate the air pollution diffusion,it considered the air pollution indicators and types,while obtained the comprehensive air quality index in order to achieve regional air pollution monitoring.Taking PM 2.5 and PM 10 pollution indicators as experimental objects,the experimental comparison results show that the PM 2.5 and PM 10 pollution indicators monitored by the designed regional air monitoring method differ little from the actual values.The values measured by the traditional method differ greatly from the actual values,which proves that the regional air pollution based on satellite remote sensing and GIS Technology is designed.The monitoring method has higher accuracy than the traditional method,and has practical application significance.
