| 摘 要： | 根据可吸入颗粒污染物对NOAA卫星可见光和近红外通道大气透过率影响的差异,通过构造卫星差值植被指数IDV,建立了该指数与地面环境监测站的颗粒物污染指数IPM10的相关关系.在卫星污染测值的定量反演基础上,结合绿地分布、绿地统计以及气象等资料,通过GIS多因子要素综合分析,对上海中心城区的颗粒物污染状况进行了动态监测和研究.

| Abstract: | Due to the different influence of inhalable particle pollutant upon the transmissivity between visible channel and near infrared channel of NOAA satellite, a difference vegetation index I_(DV) is built. And the relationship between I_(DV) and particulate pollution index I_(PM10) observed by the ground environment monitoring station is found. On the basis of quantitative reversion of pollution measurements by satellite, combining with green land distribution, green land statistics and meteorological data, a dynamic monitoring and research has been done to the particle pollution of the central urb in Shanghai by using GIS multifactor integrated analysis. |
