Qualitative Changes in Green Space of District 1 of Tabriz City within the Period 1989-2010 Using Remote Sensing Techniques

The current study aims to investigate the changes in green space of District 1 of Tabriz City in a 21-year time period (1989 to 2010) using remote sensing techniques. In this research, multi-temporal images of LANDSAT Satellite, sensors TM and ETM쇪 used to model physical development and changes in green space of the district during the years 1989 to 2010. Destructive role of expansion of urban areas and transport network have been so significant in dramatic loss of green space in District 1 of Tabriz City. The obtained results revealed that during the studied period (1989 to 2010), the green space area of the district has been decreased from 255.61 ha in 1989 to 180.45 ha in 2010 representing approximate 30% loss of green space area. At the same time, built-up areas have been expanded from 702.19 ha in 1989 to 958.14 ha in 2010 while urban transport network area of the district has been developed from 101.61 ha in 1989 to 291.24 ha in 2010. Finally, some management sterategies were recommended towards taking advantage of available opportunities for developing the green space of the District 1 of Tabriz City of which the most important is "compilation of comprehensive green space management plan".
