The existence of spatial interactions of border areas in all countries has made these areas sensitive centers. The border areas of Kurdistan Province have been able to establish extensive connections with the Iraqi border areas in the shadow of comparative and competitive advantages. In this regard, the study of interaction between settlements, spatial pattern of interactions and its development effects at the level of these areas can provide the necessary framework for sustainable spatial development planning. The present study seeks to identify and analyze the pattern governing spatial interactions in the border areas of Kurdistan province. This research is descriptive-analytical based on method, and fundamental based on purpose. Its statistical population consists of households in 207 villages and 8 border towns. Determination of sample size for rural settlements was obtained using Cochran's formula of 135 villages. For some reason such as (inaccessibility of some villages, security issues and restrictions in border areas the final sample size was confined to 46 villages. Samples were selected using two stratified and quota random methods. In relation to urban areas, in this study, all cities in the border areas of Kurdistan province were studied by full counting method. The results indicated that there is an inequality in distribution of facilities and services. This situation indicates the lack of network pattern formation and mutual flows in the area. The results showed that the flow of goods and capital in a trans-regional form and in relation to the national cross-border points of the west of the country such as (Sulaimaniyah and Erbil) and capital points (Tehran), have the greatest effects on the formation of spatial pattern of border interactions in the study area. It can be compared to a rhombus pattern (center-periphery-center). Also, service and information flows within the region have had the greatest impact on the formation of the polar or center-peripheral pattern in the study area.

Some factors such as the lack of strong urban management and lack of property control have prevented the urban body from expanding in a balanced way and has many adverse economic, physical and environmental consequences for cities. The aim of this study was to model the functional dimensions of urban management affecting the process of spatial dispersion in Yasuj. The research is applied in terms of purpose and descriptive-analytical in terms of nature and method. In the data preparation stage, the functional dimensions of urban management affecting the dispersal trend of Yasuj city were identified using the opinions of various experts through the Delphi method. For the Delphi team and the ISM team, 20 experts were selected by purposive sampling. Data analysis was performed by structural-interpretive modeling (ISM). The results showed that in terms of penetration power among the 16 identified indicators, the highest stimulus belonged to the agents monitoring the implementation of laws related to land use change and determining and monitoring the privacy and legal boundaries of the city with 16 and 15 penetration powers, respectively. The model of the present study also included 11 levels that the factor of monitoring the implementation of land use change rules (C2) was recognized as level eleven and the most effective factor. Based on the output of MicMac analysis; determining the legal boundaries of the city (C3), factors of construction supervision (C6), more access to municipal services (C1), monitoring the implementation of laws related to land use change (C2) are among the key independent and highly influential variables that affect the dispersal of Yasuj city. Therefore, urban management, as the main trustee in this field, should pay more attention to key independent components of physical performance.

The issue of rural housing is an institutional-structural process and is very sensitive and important. Success of the issue necessarily depends on the participation and interaction of all stakeholders, which includes three groups of attendees, observers and officials. The present study seeks to explain and analyze the role of rural development actors in organizing rural housing in Zanjan Township with a descriptive-analytical method. Data collection was done by two methods: field and documentary. The statistical population includes 13 sample villages in Zanjan Township with a population of 14075 people, of which 374 persons were selected as a sample according to Cochran's formula. For data analysis, factor analysis, structural equation model and multi-subject-multiplayer model were used with the help of SPSS, Lisrel and Mactor software. Findings showed that land price indices (0.665); ease of receiving infrastructure facilities (0.743); type of construction materials (0.764); and regarding the standard of facade design and layout (0.747) are among the most important factors of improving the quality of rural housing. Based on the structural equation model, actors had the most caus-effect relationships with the managerial index (5.01) and the physical index (4.82). Based on a multi-theme multi-player model, the activists of the Islamic Revolution Housing Foundation; Dehyari of the village and the inhabitants of the village "with the impetus of" residential strength; administrative costs and construction license; adherence to the standard of facade design and layout; house price; issuance of manufacturing license; resolving common housing disputes and ease of obtaining infrastructure facilities are the main factors in rural housing developments. Therefore, for the development of rural housing, some attempts need to be done, such as physical improvement; empowering the weak sections of the villages and facilitating the legal acquisition of land for the villagers.

Tehran's population has increased twenty times over the last century. One of the consequences of this increase in population is traffic problems on most days of the year. One of the requirements of reducing traffic is to reduce the share of intercity travel by private car and change it to other modes of transportation. This model is used in public transport-based development (TOD) as a solution. The TOD model has been welcomed as a new model for changing the behavior and changing the physical geometric context of cities by using technology related to the population and residents of the city since 1993 in many countries to reduce some of the urban traffic problems. In fact, the TOD model is a dense development with the right combination of land-uses in the vicinity of public transportation stations. The immediate proximity of housing, places of activity and services in buildings, neighborhoods and urban areas has become an important principle for the good shape of the city in the 21st century. The purpose of this study is to evaluate the development of density and land use mixing in the operating radius of Moniriyeh metro station in order to implement the TOD. Bbased on an applied method, first the criteria of the principle of mixing and density with the focus on public transportation were identified. Then, the specifications of the area were evaluated with the standards of the Institute for Development and Transportation Policy (ITDP). Findings show that Moniriyeh station has not met the required standards of these two indicators in order to implement the model (TOD). Also, the city is planned for a car-centric direction and needs to review its detailed plan. The results of the present study can be used to enrich the TOD literature and assist planners in evaluating the measures taken in urban development.

Among the dimensions of sustainable development, the social dimension is recognized as one of the main dimensions that is mostly associated with quality of life. Mehr buildings are built either within new cities as urban neighborhoods or separately from small towns and metropolitan satellite towns. In the metropolis of Karaj, a number of Mehr houses have been formed in the new city of Hashtgerd and the towns of Abrisham and Mahdasht separately on the outskirts of the satellite cities of Kianshahr and Mahdasht. The main question of the present study is whether Mehr housing estates in metropolitan areas have the necessary qualities to provide sustainable housing and the formation of livable settlements? Or, what is the situation of social stability in these settlements in terms of sustainable development? The research method is descriptive-analytical. Field data are collected and analyzed based on the theoretical model of social sustainability. The sample size for completing the questionnaire included 720 households in the three settlements that were selected using the Cochran's formula. The results indicate that the situation of sustainability in the three studied towns is not the same. In terms of basic needs, only the realization of housing and shelter in Hashtgerd town with a score of 3.37 and in Abrisham and Mahdasht with an average of 3.17 has been successful and other sustainability indicators in all three areas are below average and in an unfavorable situation. Also, employment and economic situation with an average of 1.46 in all three towns is unfavorable. In terms of intermediate needs, the quality of the neighborhood is better with an average of 2.16 and 2.23, and in terms of final needs, the status of capital indicators and social mixing in Hashtgerd with an average of 2.16 and in Abrisham and Mahdasht with an average of 2.23 is somehow more suitable. In all the studied samples, other six necessary dimensions for the creation of livable settlements, especially in the field of migration and population movements and the provision of social infrastructure, have been unsuccessful or very unsuccessful.

Despite the many capabilities of spatial statistics in modeling and explaining various environmental features and identifying the patterns governing their distribution, the previous studies have considerably neglected these capabilities, especially in the field of water studies. The present study aims to model the patterns governing the distribution of water wells in the Mahidasht watershed in Kermanshah province using spatial statistics. The bases used to identify these patterns are the "Locations" and "Attributes" of the wells, which are performed using five common techniques in spatial statistics, including: Average Nearest neighbor, Getis-Ord General G, Spatial Autocorrelation (Moran I), Cluster and outlier analysis, and Hot spot analysis. Required data were obtained from the Kermanshah Regional Water Company. The results of the present study showed that the pattern governing the dispersion of agricultural wells and the pattern governing the dispersion of high values (high depth of wells) in the Mahidasht watershed do not confirm the null hypothesis and follow the cluster pattern. The general pattern of dispersion of wells in the study area since 1950s to 2000s has changed from a random pattern to the cluster one. Cluster and outlier analyses as well as hotspot analysis indicated that the northern and northeastern parts of the watershed are critical in terms of uncontrolled abstraction of groundwater resources.

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).

In recent decades, with the significant increase in the occurrence of natural hazards in the world, the need for resilient cities has increased. The resilient city must have the capacity to withstand any impact, including crises and environmental disasters. According to the UNESCAP report on events related to tectonic hazards, Iran is among the top ten countries in the world and in terms of mortality due to these hazards is ranked between first and third in the world. The city of Zanjan is no exception and is one of the most vulnerable cities in the country to earthquakes due to its location next to three faults and the presence of dense and worn tissues. This raises the need to address the issue of resilience more than ever. In the present study, using a descriptive-analytical method and inorde to compare the patterns of neighborhoods of Zanjan after the Islamic Revolutionas well as prioritizing them in terms of compliance with resilience criteria, the criteria and indicators of physical resilience were extracted. Then, the criteria and indicators were prioritized using the non-structural fuzzy decision support model and examined in post-revolutionary patterns to date in Zanjan neighborhoods. The results showed that the preparation model neighborhoods have the highest resilience and the accelerated and unplanned development model neighborhoods have the lowest resilience.
