The main purpose of this paper is to study resilience in urban housing area of Saqqez city. The statistical population of the study includes residents of 22 neighborhoods of Saqqez that according to the results of the 2016 census, their number was 165.258 people. The research method is descriptive-analytical with emphasis on the practical aspects. That is a data collection tool through a library, field studies, urban land use map, use of statistics and censuses in 2016. First, the radius of performance of the outer physical criterion is determined by the network analysis in the GIS to perform the necessary analysis. Data on other criteria were collected using field surveys and statistical data and they were then weighted to prioritize the importance and needs of citizens in the AHP and finally we did the analysis in the Todim. The research results show that according to the resilience evaluation criteria in the housing area of the formal neighborhoods of 22 Saqqez city, neighborhoods 16, 17, 6, 19, 18 and 12, located in the southwest, part of the northeast and west of the city, have unbearable resilience. Improving the space and proper distribution of revenues is one of the most important proposals, along with greater cohesion and sense of belonging, monitoring of construction rules and regulations, access to the main thoroughfares network and creating financial incentives. The novelty of this study is in using network analysis software, builder and Todim to determine the radius of performance and ranking the resilience in urban housing area and in the neighborhoods of Saqqez city.

This article attempts to examine the appropriate time for tourism in the cities of Sistan and Baluchestan province, based on the physiologic equivalent temperature index (PET). The PET index is one of Rayman's software outputs, which is used to explain the tourism climate in Zahedan, Khash, Saravan, Zabol, Iranshahr and Chabahar cities. First, daily data (10957 days), air temperature, cloudiness, water vapor pressure, wind speed and relative humidity of meteorological stations of these cities were collected (1986-2015). The results of RayMan inferred in the form of daily climatic calendars. According to the monthly percentage of non-stress days (thermal comfort), the results showed in Apr (Zabol and Iranshahr, 67%), May, June, Jul and Sept (Zahedan, 28-90%), Oct (Saravan 87%), Nov (Iranshahr 87%), Des, Jan, Feb and Mar (Chabahar, 42-95%) have the best conditions for the presence of tourists. The best conditions for tourism in Zahedan (May and Sept), Khash (May, Sept and Oct), Saravan (Apr and Oct), Zabul (Apr and Sept), Iranshahr (Apr and Nov) and Chabahar (Dec, Jan, Feb, Mar and Apr) are estimated to have the highest percentage of non-stress temperature days.

his article deals with the identification of effective factors on attracting and increasing the length of stay and permanence of tourists in Kashan city. The research tool is a researcher-made questionnaire that was answered by tourists visiting Kashan. The sample size was calculated by using sample power software to 200 people and was randomly distributed among tourists in Kashan. The research in terms of purpose is applied and in term of nature it is one of the descriptive analytical researches based on field studies. This research has been done for the first time with a comprehensive and systematic approach in the region. The results of the T-test indicate that 5 components of historical, religious-cultural, natural, shopping, location and accessibility attractions are effective. Classifying the effective factors has been performed by structural equation modeling. The factor loading of 0.78 for components of religious-cultural attractions demonstrates that this factor is the most effective issue which motivates traveling to Kashan and it is more effective than other factors. Identifying effective factors in increasing tourists’ inhabitancy duration by factor analysis indicates tourists’ services and facility in Kashan, among the 6 identified factors, has 15.46% of the general variance of the analyzed collection. In other words, the improvement of services and facilities could be more effective in the rise of the tourists’ inhabitancy duration in Kashan.

This article has tried to identify and cluster the effective requirements on the design of biophilic architecture of interurban spaces in the first phase of Ekbatan settlement of Tehran, using the method of structural analysis. Theoretical data has been prepared by documentary method and experimental data by survey method based on Delphi technique. The statistical samples were 20 urban experts and specialists who were selected by snowball sampling method. 55 primary drivers in 6 statistical categories and identified by structural interaction analysis method were processed in MICMAC software. According to the results of the general dispersion pattern of the studied requirements, in terms of mutual effects analysis, it indicates the state of an unstable environmental system in which the design requirements of biophilic interspaces are complex and intermediate in terms of effectiveness and effectiveness, and the requirements are more concentrated in the cluster of independent factors. General patterns, composition of components and habitats and ecosystems have been ranked first to third by obtaining the direct influence of 311, 296 and 278, respectively, and as the most key requirements for the design of biophilic interspaces in the phase 1 residential complex of Ekbatan settlement, Tehran. were chosen. General patterns, composition of components, habitats and ecosystems, inspiration from nature, geographical connection to the place, ecological connection to the place, building form, space as shape and form, coordinating factor of shape and spatial form, natural light, defining spaces. Inside and outside, light and shade, and growth and effectiveness were selected as 13 key requirements for the design of biophilic interspaces in the residential complex of phase 1 of Ekbatan. Key forces in terms of system performance in the design system environment have a role of high effectiveness and low effectiveness. As a result, as stable requirements, it controls the macro state of the system and its changes; The key requirements of the entrance effect of the design system of biophilic spaces in the residential complex of phase 1 of Ekbatan town of Tehran are considered.

In most of the old cities of Iran, the tissues with historical value are seen in abundance, which are recognized by various characteristics such as smallness, access problems and instability. Taking into account problems such as negative population growth, lack of access within the necessary neighborhoods, and the ever-increasing expansion of space is therefore important. In ruined and abandoned tissues, not having the necessary facilities, action should be taken to solve these problems. This research was conducted with the aim of analyzing the effects of social, economic and physical factors on the regeneration of the neighborhoods of the central fabric of Kashan city (including seven neighborhoods) and the descriptive, analytical research method and the desired information was collected in the form of a survey. There were about 44,000 people in the area. The size of the research sample was estimated to be 385 people using Cochran's formula. SPSS and AMOS software were used to analyze the research data. The findings of the research showed that access to services and facilities, identity and social capital, housing ownership, and income were factors influencing the regeneration of dilapidated structures, and in the neighborhoods of Soltan Mirahamd and Darb of Esfahan, which enjoyed the mentioned privileges, residents were more inclined to re-create dilapidated structures.

The aim of the current research is the feasibility study and development of pocket parks in Iranian cities with the approach of citizen participation in Elahieh and Kooie Farhang neighborhoods of Zanjan city in response to the fact that the factors affecting citizen participation in the feasibility and creation of pocket park development in Zanjan city neighborhoods and effective strategies for development. What is the partnership of pocket parks? The present research is in accordance with the descriptive-analytical method in terms of its applied type and nature. The method of collection, library and field observation (interview with questionnaire tool), and sampling of probability type by simple random method. So far, no important studies have been done in the area of the feasibility of creating and developing park envelopes with the citizen participation approach, and the practical value of the research will be in changing, improving and modifying the methods and patterns of dealing with planning for the sustainability of cities in Iran. The results showed that trust played an important role in the development of pocket parks and increasing neighborhood dynamics, trust in each other and urban management was the basis for creating such desirable spaces. Also, the situation of the components of NGOs and feeling of security in the two neighborhoods of Elahieh and Kooie Farhang are not the same, and the conditions of Kooie Farhang are more unfavorable than Elahieh. Finally, for the development of such spaces, the sense of security variable will have the greatest impact on the development of pocket parks in these neighborhoods.

Consumer satisfaction in tourism is strongly influenced by the provision of services, the appearance of the product and the personality and reputation of the tourist destination. In this regard, the present article was compiled with the aim of identifying and prioritizing the requirements of tourists' satisfaction with urban facilities and services and in a descriptive-analytical method. Data collection was done in a library and field method through a questionnaire. The statistical population of the research included the tourists of Shahrood city that due to the unlimited statistical population of the research, 114 people were selected as a statistical sample and the questionnaires were randomly distributed among them. Cronbach's alpha coefficient was calculated to be 0.81 for positive questions and 0.72 for negative questions. Kano model was used to analyze the data. The results indicate that among the basic requirements, the factor of safety of tourism environments make greatest dissatisfaction and the factor of parks and natural spaces make least dissatisfaction if they don’t supply. Also among the functional requirements, the factor of cleanliness of urban areas and tourism make greatest dissatisfaction and the factor of Lighting engineering of urban areas and tourism make least dissatisfaction if they don’t supply. In this regard, among the motivational requirements, the factor of cultural services and facilities make greatest satisfaction and and the factor of tourism companies and tour guides make least satisfaction if they supply.

The goal of this survey is the analysis of the influence of the city spatial oraganization and the study of the city commercial functioning in relation of eachother. The mono centrality and the poly centerality of the cities have an important influence on the trip distances, preventing the waste of time and energy in the cities. The vehicles produce the greenhouse gases and increase the earth warming in a long run. The recognition of these factors can decrease the amount of greenhouse gasses and prevent the global warming.The type of research is practical and the analysis method is analytical descriptive. This research has been done after the scientific studies in order to estimate the greenhoause gases on the suggested Clean Development of CDM. The Mashhad metropolis spatial organization has been studied in two scenarioes. The first scenario, namely the mono centrality of the existing city and the other scenario, alongwith triple centrality spatial organization,along the city structure have been considered. The Mashhad metropolis balanced spatial organization has decreased the green houase gas emission up to 43 percent for the private cars . The average trip distance, traveled by the private cars in balanced spatial organizition is decreased about 4 kilometers. The decrease of the greenhouse emission rate for each passenger is 7.9 kilogram CO2 . The distinction and innovation of this research is to examine the relationship between the centrality index in the spatial organization of metropolises and the amount of greenhouse gas emissions.
