Spatial analysis of green infrastructures in Tehran's district 22 using the principles of spatial planning

Abstract

Objective: The destruction of the life support system, also known as the green infrastructures, is one of the challenges posed by population growth and increased land consumption. Green infrastructures are as essential to modern societies as conventional forms of infrastructures and their loss imposes hidden costs on the community. Green infrastructures are of the utmost importance today since they provide various ecological services to settlements. Methods: We first review the theoretical foundation as well as the available thematic documents of the district. We then study the green infrastructures of the district using Cartosat-1(IRS-P5) satellite imagery from 2008 to 2015. Results:we apply the principles of the comparative validity of research in the area of ​​settlement classification to validate the future stages of the research. We have then attempted to detect variations using the model. In the next step, spatial planning factors including spatial distribution, expansion, neighborhood, and sufficiency have been analyzed using spatial statistics techniques in ArcMap. Conclusion: The results of this study indicate that the transformation and expansion of green infrastructures do not conform to the principles of spatial planning, which points to unbalanced spatial distribution, inconsistency, moderate adaptability, and the inadequacy of green infrastructures.
