The present study applies quantitative-survey method and secondary data to evaluate and spatial analysis of urban physical sustainability in Chaharmahal and Bakhtiari province. First, 22 objective indicators of physical sustainability were selected using CVI and CVR methods. Then, the Principal Component Analysis (PCA) method was applied to evaluate the physical sustainability of the cities. Also, for spatial analysis of the distribution pattern of urban physical sustainability in the province, spatial autocorrelation (Morans I) and inverse distance weighting interpolation (IDW) method were used. Based on PCA method, findings indicated that four principal components (namely; urban landuse, worn textures, intra-urban accesses, infrastructures and communication technologies) with a cumulative variance of 64.548% explained the correlation between research variables to measure and evaluate urban physical sustainability in the province. Based on spatial pattern analysis method, results showed that there is a cluster pattern of sustainability around the whole province as well as a rather concentration of physical sustainability in cities closer to Shahrekord (the province center).

The present study, using spatial analysis models and in the framework of the "spatial diffusion" approach, has evaluated the position of the central core of Torqabeh city from the perspective of population groups. This evaluation includes two periods: 1- Slow growth (before 2006) and 2- Rapid growth (after 2006). Research variables include population, number of women, elderly, youth, employed, unemployed and illiterate. The scale of analysis comprises 1476 urban blocks and three periods of 1996, 2006 and 2016. For this purpose, a spatial database including the population characteristics of Torqabeh city and its central core was created and then data were analyzed using spatial statistical tools and techniques such as Getis-Ord Gi and Grouping Analysis. The results of this evaluation showed that before 2006, the central core was the origin of all population groups and was different from other urban areas. But after 2006, population groups with the dominant pattern of "continuous spatial diffusion" move out from the central core and settle around it. Spatial analysis models show that as a result of these changes, the central core of Torqabeh does not lose its position compared to other urban areas. Rather, this process causes some areas to become more similar to the central nucleus and the population characteristics of the central nucleus to be multiplied in other regions. The spread of population groups around the central nucleus and its adjacent areas, on the one hand, indicates the desire of individuals to be present in this area and show spatial cohesion, and on the other hand indicates the existence of a distinct pattern of central nucleus changes in physical growth which is different from common patterns in large cities.

In housing category, preparation of plans and programs for social and physical dimensions of housing can prevent gaps and inequalities of resident’s well-being and the city’s unplanned growth. Accordingly, the aims of the present study are: the spatial analysis of social and physical dimensions of housing, showing the imbalance proportion of supply and demand for housing, and showing the relationship of housing shortage with horizontal expansion of Ahwaz city. Based on type the present study is an "applied-developmental" and based on method it is a "descriptive-analytical" research. Required data was collected using a library-documentary method. A total number of 20 social and physical indicators were applied for leveling the regions of Ahwaz city. Data analysis was done based on several methods such as; Superiority and Inferiority Ranking (SIR), Holdren, Shannon's Entropy, Pearson Correlation Coefficients, and Visual PROMETHEE software. Findings of the present study indicated that regions 2, 3, 4 and 8 are in a favorable situation in terms of social and physical indicators, whereas, regions 1, 6 and 7 possess a different social and physical situation. It shows an imbalance distribution of affordable housing across the city of Ahwaz. The Pearson correlation coefficient with a sig of two-sided 0.501 confirmed the imbalance supply and demand of housing in Ahwaz. Also, the results of Holdren and Shannon’s entropy methods represented an unplanned expansion of residential areas during 2006 to 2011, but such development was not coincident with housing demand and has taken place in regions where housing shortages have not been severe. This can be considered as an indicator of unsustainable growth of Ahvaz city in the housing sector.

Urban green space is one of the land uses that its distribution across the city is crucially important. Ardabil can be considered as a city with an inappropriate distribution of green space. The allocated green space per capita in Ardabil is 7.3 square meters. This figure is quite far from the indices determined by the United Nations Environment Organization which considers 20 to 25 square meters for each person. The present study was aimed at analyzing 44 neighborhoods of Ardabil city based on 11 selected indicators of green space availability set by experts. Based on type, the present study is an applied research with a descriptive-analytical method. The required data was obtained from the parks and green space organization of Ardabil in 2015 as well as through a field study. Then, in order to rank all 44 neighborhoods of Ardabil city according to their existing green spaces we have applied the Copeland model to integrate several multi-criteria decision-making models including TOPSIS, VIKOR, ELECTERE, and SAW. As a result, all neighborhoods of Ardabil were grouped into four categories namely: enjoyed, semi-enjoyed, deprived, and very deprived. As seven neighborhoods of the city lacked any kinds of green space, and most of the other neighborhoods fall in the deprived category, it can be said that the distribution of urban green space in Ardabil is an unbalanced distribution.

Based on the definition of social happiness advocated by veenhoven, it can be posited that he considers happiness as the type of behavior that leads to desirable quality of life. The purpose of this paper is to define and analyze social happiness at urban areas. First of all, it should be noted that one who drives happiness by spreading joy through energetic behaviors and expressions, charm, humors and passions in friendly and intimate circles is considered as belonging to the warm-type happiness promotion category. Further, one who conveys a good sense to others belongs to the cold-type happiness promotion category. After interviewing the happiness promoters in this study, we came across people who were the opposite of the former group. We labeled them as happiness reception, who absorbed joy and happiness in the intimate circles. Based on this classification, it should be stated that as far as social vitality in cities is concerned, the social happiness variable and its components play a significant role in the life of individuals and urban planning. Based on this process, in the present paper a mixed research methods was used. The first step involved a qualitative study (collective case study). The second step was a quantitative analysis (survey) and the last step was the point interpolation. Based on these three steps, a random and spatial-regional based sampling was conducted. The research area was the city of Mashhad and its districts during the second half of 2018. The data collection instrument was a semi-structured interview, an interview-based questionnaire, and a spatial distribution mapping of the findings on the urban areas. The results showed that the social vitality of citizens was at the average level. Meanwhile, districts (1-2-4-5) were lower than average; district 9 was at the average level and districts (3-6-7-8-10-11-12 and Samen area) were higher than average. In terms of the social happiness, districts 10-11-12 had the highest and districts 1-4-5 had the lowest social vitality. In the urban areas of Mashhad, districts 10 and 5 had the highest and lowest social vitality among the 13 urban districts of the city, respectively.

The aim of the present study is to analyze the spatial distribution and to show the spatial patterns of advanced producer services (APS) in Ardabil; one of the middle-sized cities in Iran. Sample of the study comprises 2100 activity units in four groups of advanced services, including banking and financial services, healthcare and remedial, real estate, and insurance services. Documentary and field methods are applied for collecting and processing the data. Spatial statistical techniques such as Kernel Density, Average Nearest Neighbor, the local Moran statistics, Cluster and Outlier spatial analysis, Hot Spots and Geographically Weighted Regression (GWR) methods have been used in GIS environment for data analysis, density estimation, distribution pattern analysis and conceptualization of spatial relationships. The results show that, insurance and real estate consulting services are enjoying the highest levels of coverage around the city. The highest densities of ASPs belong to center and south parts of the city. The spatial pattern of the advanced services is spread in type. Spatial pattern and spatial distribution of insurance services and real estate consulting are dispersed around the city, but the spatial pattern of banking, health and remedial services are clustered. The gravity or central point of advanced services locates at the geographical center of the city and the movement path of the advanced services follows a north-south route. There is a significant relationship between population density and some kinds of advanced services. Finally, some recommendations are presented based on the findings of the study.

Today, natural disasters and damages caused by these accidents in different parts of the world have made making cities safer to become a long-term and achievable challenge so that urban communities are looking for conditions to reduce the damage so they can get to pre-crisis situation as soon as possible. Meanwhile, viability is an important way to strengthen communities and cities by using their capacities. In this regard, the present study uses a descriptive-analytic method to investigate the viability of Babol area against environmental hazards that’s questionnaire was arranged with four dimensions, 16 indicators and 31 sub-indicators and total of 383 questionnaires were distributed randomly among the statistical population of the study, based on the Cochran model. To investigate the research issues and data analysis has been used from the multi-variable decision-making model "VIKOR" and the standard weights of each of the indicators have been calculated using Chanol Entropy method. The results of the research data were analyzed using SPSS, GIS and Excel software it is shown that among different dimensions of urban vibration in 12 areas of Babol, physical dimensions (with a mean of 3.54) and then social (with an average of 3.14) are more appropriate but in general, about 50% of the studied areas in Babol have low glare and irregularity and only 25% of the regions are quite viable in terms of indicators.
