Assessment of the Physical Indexs of Urban Housing by Sustainable Development Approach Case Study: City of Saman

Now days housing is one of the most acute problems of developing countries، so that internal migration and problems related to land supply، lack of resources، poor economic management، lack of comprehensive planning، housing and other infrastructure deficiencies are the relate in the country's economy. on the one hand، the rapid increase in urban population as well as the providing of shelter in the country to form complex and multi-dimensional render; Therefore، this way to cause the continuing cities of development in the future and the predictions of contain of the increase in pollution، ecological degradation in urban areas. Along with these developments and concerns of sustainable development theory، its origin dates back to the last decades of the twentieth century، increase. according to the important role of cities in the development of the current instability، theory of sustainable urban development is of great importance and widespread effects on urban environments in order to fulfill the objectives of sustainable development of urban housing. So that the housing sector is an important role in this topic. Saman city is one of Bakhtiari province. Putting into the riverbank Zayanderud and also having the role of agriculture-tourism، high population growth in recent years that have migrated from neighboring villages to Saman. This migrating increased population، so، the providing of house are important for them. The purpose of this study is to investigate the physical approach to the sustainable development of urban housing in the city is Saman. Theoretical bases: The housing has a determining role in the shaping of cities. at the same time in terms of various parameters have been many problems. On the other hand، it is noteworthy that appropriate housing، welfare and psychological aspects also it is an important of role in the town. Therefore، identification of suitable housing indicators and efforts to achieve favorable habitat، it is important to discuss sustainable urban development. Martin Haydygr German philosopher with a qualitative approach to housing issues، believed that the real crisis of the housing it's not shortage، But the real crisis in search of man is to live; man must live ever before learning to learn. His live، build، growing and developing are knows synonymous. Indeed، sustainable development can be defined as a balance between ecological، economic and social protection and it development are depends on the quantity and quality of dealing with resources، skills and community housing development. In addition، can be depends on the environment and social affects، economy and culture. These are includes the development of upward economic and social change. So that urban housing is one of the most important elements in the sustainable development of the city. Mentioning is that one of the most knows aspects in the development of sustainable housing. So that today the housing is effective on change of the natural environment، culture، economy and social of problems. This will allow to the next generation for the providing a good living. Housing Sustainable is defined as a incompatibility of housing and contrary with his environment in the wider area of the world The results indicating that the city is settled in the relatively poor satiation. So that، in all four areas of the city، the materials indicator is lower than average. Region three and four are the most desirable and undesirable areas on the quality of housing indicator respectively، on the building date indicator region three and two were most desirable and most undesirable respectively، region one was most desirable and region three most undesirable in facade indicator، finally، in terms of floors number indicator region two and three were most desirable and most undesirable respectively. However، in the final housing structure indicator، region three was most desirable and region two most undesirable in Saman's housing structure. The five components of physical indicators of housing in Saman to make a decision after a review of the model are analyzed by Vykvr it was found that the three degrees of desirability، 0. 00 in the first place and the degree of compliance with 1. 000، is in last place. Also the quality grade four to grade a quality 0. 955 0. 694 in the third and fourth respectively. The housing deterioration in Saman city، in the mountainous climate conditions، is more consistent and coordinated approach to sustainable development with attention to modernization of old and destruction is necessary. In view indicators the most desirable and undesirable area، an area which is three due to the low level of acceptance of the use of aluminum storefront is low، The aim of the current study is to evaluate the structural parameters of urban housing with a sustainable development approach. This study is a descriptive analytical study. The AHP's hierarchical model was used to weighting the indices and for evaluating and rating the stability of each of the urban areas Vicor and TOPSIS decision making techniques were used. In this study five structural parameters including materials or skeleton of the building، housing quality، old buildings، facades of houses and the number of floors were examined. The results indicating that the city is settled in the relatively poor satiation. So that، in all four areas of the city، the materials indicator is lower than average. Region three and four are the most desirable and undesirable areas on the quality of housing indicator respectively، on the building date indicator region three and two were most desirable and most undesirable respectively، region one was most desirable and region three most undesirable in facade indicator، finally، in terms of floors number indicator region two and three were most desirable and most undesirable respectively. Suggestions: In the current study and according to the findings of research in the physical desirability of housing turnover the following suggestions are offered in the Saman city. 1-Use more resistant materials such as steel and concrete in the areas of housing، especially the one and two to four in order of strength and resistance to natural disasters، is essential. 2. Increase the percentage of acceptable housing and repair durable and destructive strength of the housing in the area of the city is required. 3. The modernization and improvement of housing in the area and an area for further strengthening its priority. 4. The increased use of aluminum and composite view in the two and three beautiful part of the building in the style of the times is essential. 5. Using two and three floors of housing in the short and medium term from four to five storeys in order to conserve the land and the creation of intelligent and programmable stabilization city.
