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.

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.

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.

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.

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.
