Green Space Site Selection in Tabriz County by Using Geographic Information System (GIS)

Increment of soil carbon is an appropriate method for reducing atmosphere dioxide carbon density resulted from foresting in the unutilized and destroyed lands and its optimal management due to increase of concern about universal heating and changing of climate. According to universal heating and expansion of urban industries issue in the air pollution; capacity of Tabriz Province lands in establishing of parks has been investigated by employing AHP. The data were collected by available basic maps and spot 2005 satellite images and also field studies. The zone digits of maps were converted to criterion maps (slope، direction، height، land usage، geology، soil، city، communication network، village and rivers) by using spatial information techniques and they were valuated for paired comparison. The value of each scale was considered according to capacity of each unit. The paired comparison of the spatial information techniques criteriawas conducted by using Marionian attached program in GIS and the studied criterion weight were calculated. Then the final map in raster format was extracted by using each weight and was categorized in five classes range from very weak to very good and the best location was extracted with an area about four percent of the whole Province.
