Abstract
According to several types of research, one of the most important issues and principles of sustainable development that urban professionals pay attention to it recently is Just City. One aspect of Justice in cities, spatial justice, has particular significance by Unequal and discordant Expanding in cities regarding creating unequal areas. On the other hand, the urban spatial structure affects the equal distribution of elements and services. If this structure is devoid of justice ideology will lead to a complex social crisis and spatial issues as spatial conflict. Accordingly, this study aims to analyse the spatial justice and structure in the case of Yazd city to know how they influence each other. Spatial justice is examined from the view of "Equality of opportunity". Involved criteria are "equality", "Physical diversity", "human diversity" and "urban spaces", and spatial structure based on “Space Syntax” technique with "integration", "control", "connect" and " intelligibility " parameters. These criteria are Scored and analysed by FDAHP techniques and GIS. The result shows favourable status in the Central District, and as getting away from the disadvantaged downtown District increased. On the other hand, the spatial structure analysis reveals the most spatial coherent analogue the north-south axis with a little depth and isolated District (Spatial segregations) have located in the corners and edges of the city. Results from the superposition of these two analysis layers show a compatibility relation between the spatial structure of Yazd and the pattern of justice distribution except in the central and historical centre.

Abstract
Functional and structural changes of regional system are ongoing spatial changes that form patterns of spatial organization, depending on dominant regional forces and factors. Spatial structure of West Azerbaijan province experienced significant changes during 15 years; thus, the present research aim to investigate the manner of spatial distribution of two variables of population and activity, and correlation of these variables with spatial structure of the province during the years from 1996 to 2011. Quantitative method was employed for this aim and urban rank-size index was used to analyze settlement pattern of West Azerbaijan province; Kernel density and Moran method was used to analyze population data; general and local Moran data were used to analyze activity data; and regression method was used to see the degree of correlation between these variables. The results showed that spatial structure of west Azerbaijan was monocentric in 1996 while the of spatial distribution trend of the population and activity indicated decentralization tending toward clustered spatial pattern during 15-year period of time, due to high correlation between the given variables. In other words, some kinds of decentralized convergence took place. Such trend would change the spatial structure in West Azerbaijan province and needs to be properly oriented in the future planning of urban and regional development.

Abstract
In recent decades, remarkable changes have occurred in the spatial structure of metropolitan regions, creatingdiscontinuous, scattered and polycentric development which have significant implications for commuting patterns. This study examines the dynamics of spatial structure using interaction flow patterns in Mashhad Metropolitan Region (MMR). Four dimensions - centrality and dominance, network cohesion, interaction strength and levels and hierarchy - were used to analyse population flows in 1999, 2007 and 2012, showing that the interaction between Mashhad and other cities in the MMR increased over the time. However, the growth was inflows to the principal city grew considerably while the outflows decreased from 1999 to 2012 suggesting that the spatial structure of the MMR is monocentric despite the focus of development policies on polycentric development. Thus, it is necessary to adopt an integrated and multi-sectoral approach to develop a polycentric metropolitan region in order to protect the environment and reinforce inter-city relationships, manage travel demand, reduce unnecessary trip, and restrict sprawl. These policies lead to more convergence and polycentric development.
