93 Thermal Monitoring of Land Use Cover Due to Developing the South Pars Energy Zone Using Satellite Images Aliakbar Malekizadeh aa maleki@na iut ac ir Date of Submission 2014 12 29 Department of Natural Resources Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor Hossein Moradi hossein moradi@cc iut ac irAbstractPars Special Economic Energy Zone PSEEZ was established in 1998 for the utilization of South ars oil and Pgas resources The gas resources of PSEEZ is about 9 of all gas reservoirs explored in the world Since 2002 the operation at the PSEEZ is active It is planned that the PSEEZ will have about 28 phases of refineries andpetrochemical plants Before coming oil and gas activities to the region there was a unique landscape asmangrove forests muddy coasts wetlands rangelands farm lands etc Although all the phases are not operatingbut the landscape totally has been changed Usually the industrial activities cause an increasing in the localtemperature directly e g stacks and flares or indirectly landuse cover changes In this paper we studied thelanduse cover changes as well as the changed in local temperature from 1998 to 2013 To do this we used theLandsat5 TM and Landsat8 OLI satellite images between May 1998 and May 2013 We made the temperaturemaps from Infrared thermal bands i e TM 6 and OLI 10 using Artis method Our results showed that a 100 increase in industrial zones and flares areas a decrease of 34 11ha in mangroves cover mostly in Basatin Bay and a decrease of 12864 ha in natural rangelands mostly in mountains toward industrial zones are the majorchanges However the wastewater releases from Phases 9 and 10 could be a reason to destroy the mangroves Marine watercourses in our study area have been decreased by 1761 7 ha where 1509 ha has been changed tobare lands and 119 ha to industrial zones This decrease is because of filling the shallow waters and drying theMohr River Moreover the wet lands have changed from 6683 ha in 1998 to 418 ha in 2013 Comparing thelanduse cover changes with the temperature map revealed a positive correlation The results showed that themean temperature increase by 2 86 C from May 1998 to May 2013 The findings showed that temperatureranges are different in two dates where in 1998 is between 24 C 55 C and for 2013 is between 25 C 61 C Moreover in 1998 temperature class 26 C had covered the most area of the studied area by 34224 ha where thishas decreased to 24416 ha in 2013 In 1998 in overall only 7400 ha had the temperature lower than 26 C but in2013 only 5 ha In 1998 the area of the temperature class 37 44 C was 58366 ha which is decreased to 18852 hain 2013 The area of temperature class of 45 C 49 C I this time period did not changed and was about 60000 ha Therefore the major changes in area of temperature class happened in 50 C 55 C which increased from 10569 hain 1998 to 56760 ha in 2013 In 1998 the latest temperature which is observed in the study area is 55 C with 25ha but in 2013 we observed a new class of temperature 55 C 61 C with 3824 ha If we have a closer look at thelanduse cover changes map and temperature map we could found that changing the shallow waters to bare landsand industrial lands caused an increase of about 17 C in the filled areas Moreover making dry the wet lands forindustrial lands has been caused an increase of about 5 C to 6 C where this increase because of the Mohr River isabout 14 C Our results revealed that although the industrial development and its activities has a direct impacts onlocal temperature but the landuse cover changes coming by the development has also a major impacts Keywords Landsat images Industrial developments landuse cover changes Temperature changes South Pars Energy Economic Zone
