TY - Jour T1 - 使用逆向和GIS的环境空气污染预防区的识别：A模型研究Y1 - 2011-11-21 N2 - 本研究已经进行了九个曼大尔的空气污染活动的空气污染区和风险区域地图Nakkapalli，Elamanchilli，S。Rayavaram，Achchutapuram，Rambilli，Anakapalle，Munagapaka，Visakhapatnam区的Paravada Kasimkota，占地面积1355平方米。The study area is located between north latitudes 17° 19’ and 17° 46’”and east longitudes 82°35’ and 83°10’ and is covered in the survey of India topographical map numbers 56H65 K/10,11,13,14,15M 65 O/1, 65O/2.The IRS-P6, LISS-IV geo coded Remote sensing Satellite data and the above top sheets from Survey of India (SOI) are acquired for primary analysis. Using Visual Interpretation technique different thematic maps are prepared like base map, drainage map, Geomorphology map. These thematic maps were scanned and digitized using AutoCAD and converted into GIS. Air samples are collected from sampling stations were established in the study area using this sampling analysis was carried out as per the national ambient air quality standards (NAAQS), with respect to RSPM, TSPM, NOx, Sox. Based on the above data Topology is created by linking the spatial data file and attribute data file. GIS overlay analysis derived maps has been developed like Air pollution sensitivity map, Air quality map, Dispersion sensitivity map,Aerial sensitivity Mapwas carried out to find out the above parameters pollution lodes in the study area, Finally integrating of the all the above maps based on this maps Risk area map for Air pollution activities maps has developed. This kind of studies is very useful for Pollution Prevention in industrial areas and also useful for the planners decision makers for management and monitoring of industrial areas.
