Introduction
Housing is more than a mere physical shelter and be included all public facilities and services necessary to live better human being and be sure to provide a relatively long tenure. In Persian Housing means place of peace and quiet. Residential space in underlying a safe and healthy family environment. Today, despite the development of technology and communication, environmental and climatic conditions in human are effective to create the proper environment and affordable housing. Housing is considered as the most basic human needs of the smallest settlements and leading constituent element of geographic phenomena. The Rapid process of urbanization in developing countries and the housing crisis in cities cuse the spreading slums and informal settlements in most of these cities. Currently providing adequate shelter, services and municipal facilities are the major problems of the urban population that is increasing in countries. The more extensive housing are studied the plan has caused from different perspectives including architecture, construction techniques, residential facilities, buildings, land and building costs, housing credits, etc.
Iran's policy is planned based on two factors: demand and supply of housing. Countries that are faced with housing shortages public housing units in terms of quantity and quality are very important. But gradually the housing problem is reduced. Private ownership of manufactured housing by the private sector is flourishing. Therefore, the main residential use of space to provide the most basic needs of the people that have varying the human In the Urban Spaces. For more than a sense of public space transfer the social and economic dimensions. Thus the main problem that Bonab is facing with, Underdevelopment of quality and quantity of housing. The purpose present study is analysis of indicators, factors causing. Thus the development of Bonab and grading of each of the districts has been done.
Methodology
This research is applied research in which the researcher observed and analysis the districts in different ways along with the identification of capacity development of constraints or obstacles as well as it looks. In the meantime to achieve the necessary information for housing needs study and review of documents and information in relevant organizations such as Municipality, the Roads and urbanism organization and Statistical centers is paid. In this paper, cluster analysis is used to evaluate studies. Cluster analysis is a statistical method to identify homogeneous groups or clusters and includes an extensive set of techniques is designed to find a group of similar items in the data set. Cluster analysis or clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense or another) to each other than to those in other groups (clusters). It is a main task of exploratory data mining, and a common technique for statistical data analysis, used in many fields, including machine learning, pattern recognition, image analysis, information retrieval, and bioinformatics. Cluster analysis itself is not one specific algorithm, but the general task to be solved. It can be achieved by various algorithms that differ significantly in their notion of what constitutes a cluster and how to efficiently find them. Popular notions of clusters include groups with small distances among the cluster members, dense areas of the data space, intervals or particular statistical distributions.
Results and discussion
It can be seen that the land allocations hasty in recent decades in Bonab. Loss of management in land allocations has caused vast dimensions of urban land in the marginal zone, which entrusted to various species. In addition to ensuring the exploitation of urban land, followed a lot of targets. Based on this inconsistency today are seeing the development of city with surrounding villages which results in many problems in the housing sector In new towns and neighborhoods. The housing sector in Bonab has numerous weaknesses and shortcomings, that both related the quantity and the quality. What is certain the housing situation in our country due to urban development in the last century. Wrong policies Planning, Liquidation shortages, Unwillingness of the private sector In financing for housing low-income groups, Lack of policies and laws limiting recurrent transactions of land and housing, High percentage of low-quality housing and standard cause and difficulties in this section. Therefore, planning should be done in such a way that these threats can be turned into opportunities.
Conclusion
What results from this analysis are based on cluster analysis revealed in assessing housing conditions in Bonab several significant point is very impressive:
The first: Maintain the social context and of features rural and urban In terms of ethnic proximity and family ties in the neighborhood, Where most houses have been constructed as a single unit.
Second: The growth and development by increasing the number of residential units to be connected in the same situation occurs.
Third: Environmental factors, natural and unnatural elements in BONAB particularly, access and communication status as a focal point at the junction of North West Tabriz At the entrance of the provincial capital. With creating interest in the field of housing for residents in parts of low slope and plain to the East and North, it has been effective. Calculating the area of each residential neighborhoods and prioritize them based on cluster analysis was attempted. The analysis results indicate that most neighborhoods in the first cluster housing have the highest status utility (developed), quarters of 2, 14 and 15 in the rankings heading the second the relatively favorable relatively poor in the third and fourth quarters cluster, quarters 8 in the fourth are relatively poor. Also the quarter 4 and 8 are not in good condition, this can cause the development of Bonab from the north to Tabriz, in recent decades due to uneven expansion and sprawl of Bonab neighborhoods are not in good condition
