Spatial justice refers to the rule of conditions in which resources, benefits, power, and wealth of society are distributed in a balanced manner. This can be seen in the relatively balanced distribution of development indicators at national and local scales. The aim of the present study is to reduce regional inequalities and strengthen spatial justice in Zanjan province using land planning. This study is applied in terms of its purpose and descriptive-analytical in terms of its nature of collecting information, and 28 sub-criteria have been used based on documentary-field studies and surveys in relation to the subject and purpose of the research. For analysis, the data were standardized and the Shannon entropy method was used to weight each of the indicators. Then, using the Electra model, spatial justice was ranked for each of the cities of Zanjan province. The results of this study indicate that Abhar, Khorramdareh and Mahneshan counties are the most prosperous and Tarom, Soltanieh and Khodabandeh counties are the least prosperous. Counties such as Zanjan and Ejrud are always below the development threshold in terms of spatial justice components compared to the prosperous counties of the province, so that they are classified as disadvantaged counties. Zanjan county was identified as one of the most disadvantaged counties due to its high population growth and the mismatch between the growth of spatial justice indicators and population growth. Given the central role of this county in Zanjan province, it is necessary to make the necessary plans in this regard.
