چکیده
از نقطه نظر جغرافیایی عدالت فضایی شهر مترادف با توزیع فضایی عادلانه امکانات و منابع بین مناطق مختلف شهری و دستیابی متناسب شهروندان به آنها است، زیرا عدم توزیع عادلانه آنها به بحران‌های اجتماعی و مشکلات پیچیده فضایی خواهد انجامید. منطقه 6 از جمله مناطق شهر تهران میباشد که به علت غلبه نسبی فضاها و کاربری‌های فرامنطقه‌ای با کمبودهای شدید خدمات شهری و سرانه‌های کاربری فضای سبز، بهداشتی درمانی، ورزشی و فرهنگی در سطح محلات مواجه است. از این رو در این مقاله ابعاد عدالت فضایی در منطقه 6 کلانشهر تهران مورد بررسی قرار گرفته است. روش تحقیق مقاله حاضر توصیفی - تحلیلی و نوع آن کاربردی است که در آن اطلاعات به صورت اسنادی و کتابخانه‌ای گردآوری شده‌اند. در این مطالعه، جهت سنجش شاخص‌های عدالت فضایی اعم از اقتصادی، اجتماعی و کالبدی، از داده‌ها و اطلاعات بلوک‌های آماری سرشماری 1395 کلانشهر تهران استفاده شد. به منظور بررسی عدالت فضایی در منطقه 6 شهر تهران، از تحلیل لکه‌های داغ و خود همبستگی فضایی در محیط نرمافزار آرک جی.ای. اس استفاده گردید. نتایج پژوهش نشان می‌دهد که محلات آرژانتین – ساعی (3527 خانوار) و ولیعصر (3272 خانوار) بیشترین برخورداری را از شاخص‌های موجود به خود اختصاص داده‌اند. همچنین، محلات فاطمی (9309 خانوار) و وصال (2664 خانوار) کمترین میزان برخورداری از تعداد شاخص‌های موجود را دارند. همچنین براساس بررسی‌های انجام شده مشخص گردید که محلات منطقه 6 تهران از نظر توزیع شاخص‌های عدالت فضایی در وضعیت مطلوب قرار ندارند.

چکیده [English]
Introduction
The city's spatial justice is synonymous with the fair spatial distribution of facilities and resources between different urban areas and the adequate access of citizens to them from a geographical point of view. Because their lack of fair distribution will lead to social crises and complex spatial problems. District 6 is one of the areas of Tehran that due to the relative dominance of spaces and trans-regional uses, faces severe shortages of urban services and per capita green space, health, sports and cultural facilities at the neighborhood level. Therefore, in this article, the dimensions of spatial justice in District 6 of Tehran metropolis have been studied. District 6 is geographically located in the central part of Tehran, which is limited to district 3 from the north, district 7 from the east, district 10, 11 and 12 from the south, and district 2 from the west. This district with an area of 2138.45 hectares includes about 3.3% of the city. The largest area within it is area 4 with an area of 79.470 hectares and the smallest of which is area 3 with an area of 7.242 hectares. This district is one of the relatively old areas of Tehran, which is located in the city center. The most important administrative-service uses with urban, trans-regional and even national performance scale are located in this region. Also, one of the oldest and largest north-south axes of Tehran, Valiasr Street, passes through the center of gravity of this area.
Materials and methods
According to the nature of the subject and objectives of the research, the research method is descriptive-analytical. The information has been collected in the form of documents and library studies. In this study, first, economic, social and physical indicators were selected. The source of citing the indicators and quantities used are data and information of the statistical blocks of the 2016 general population and housing census of Tehran. After the studies, 12 items of economic, social and physical indicators, which could be accessed in the district 6 of Tehran, were extracted for spatial analysis of the mentioned indicators. Then, based on these indicators, using hot spot analysis and spatial autocorrelation in the Ark GAS software environment, spatial analysis was performed in District 6 of Tehran. Finally, Moran's statistic was used to determine the type of distribution pattern or distribution of inequality in District 6.
Results and discussion
Findings show that in general, the neighborhoods of Argentina- Saei and Valiasr Square have the most indicators. Also, Fatemi and Ghezel Qaleh neighborhoods have the lowest number of available indicators. While Fatemi and Ghezel Qaleh neighborhoods are among the most populous neighborhoods in Region 6. Also, according to surveys, only 5% of the district is in desirable conditions in terms of spatial distribution, while 45% of the area is in undesirable conditions.
Conclusion
Based on the results of the present study, the neighborhoods of District 6 of Tehran are not in a desirable situation in terms of the distribution of spatial justice indicators.
