Investigation on modern history of urban planning in Iran shows that there are three approaches in the subject under discussion: “Modernism and Westernism”, “Traditionalism and anti-Westernism”, and “Adopt and Adapt”. Proponents of the first approach believe in encouraging methods to use the external concepts. The second, is the idea about ​​cultural and religious values, ​​thereby everything with nontraditional orientation is rejected. In the third approach the thinkers believe that if the parts of tradition are synthesized by modernity, culture and religion can adapt themselves with the development. The purpose of this study is to evaluate the adaptation of traditional urban design patterns of Islamic-Iranian cities in incompatible district of new Iranian cities (spontaneous settlements) and to focus on the application of the third approach in the current situation of Iranian cities. On this basis, the method of comparative analysis has been applied to survey the differences and similarities between historical districts and spontaneous settlements. Studies show that there are rather similarities among physical - spatial parameters (such as structural and environmental criteria) between the two types of districts; because both of these residential districts formed as organic structures that are unstable against unexpected risks and earthquake. However, there are the differences between these two types of districts in organized and formed periods. Despite historical districts that have been consolidated and organized during hundreds of years, spontaneous urban textures formed quickly and without any plan and planning. Meanwhile, the historical districts have usually integrated townscapes and unique materials such as clay, bricks or stone, while this character (integrated townscape and unique materials) never have been seen in the spontaneous settlements. There are similarities in economic and socio- cultural characteristics between residents in the two the types of districts. The residents living in poor economic condition, but under a very strong socio-capital and traditional beliefs; There can be seen several socio-cultural and particularly religious characteristics in people of historical residential districts that are similar with the spontaneous residential places, such as “strong relationship among families, friends”, “hospitality”, “mutual relationship among family members”, strong religious beliefs and the needs for privacy and security. However, these communities are different in some principles such as quality of life and spatial and physical qualities especially in favorable and beautiful urban landscapes. So it can be extracted and adopted excellent principles from traditional and historical districts and adapt them to the inappropriate modern urban districts. With regard to the existence of these similarities, we explain applicable principles of the spatial characteristics and designing quality in the historical district of Yazd to apply in Baghshater District in Tehran as a spontaneous settlement. Findings show that we can use several solutions to reconstruct this zone included: 1) land readjustment as the suitable solution in Baghshater District with regard to the familial residential pattern in historical zone of Yazd such as Fahadan District. 2) Focusing on the traditional concept of mutual relationship in residential houses. 3) Emphasizing on the hierarchy of The entrances and exits of the residential units.

the purpose of this research is to prioritize the indexes of discretion, Heterogeny and Autogeny factors in order to analyze and evaluate their readiness for ideal situation of Central bank of the Islamic Republic of Iran (CBI). This research is an exploratory kind and in terms of method is a survey kind. The data collection tool is questionnaire. After two Delphi cycles, in final questionnaire the detachment variable was eliminated and for Autogeny variable 10 questions, Heterogeny 11 questions and discretion 17 questions were regulated, therefore it can be said the ostensible and content validity of the questionnaire was confirmed. Also since Cronbach's alpha coefficient of the questionnaire was higher than 0.7, it indicates acceptable reliability of the questionnaire. In order to analyze the data, Friedman test with applying SPSS software was used. The results showed, the structural dimension with average grade of 1.83 had higher average than contextual dimension which means in Discretion factor, the structural dimension has more readiness for ideal situation. Also the structural dimension with average grade of 2 had higher average than contextual dimension which means in Heterogeny factor, structural dimension has more readiness for ideal situation. And finally, the contextual tent dimension with average grade of 1.91 had higher average than structural dimension which means in Autogeny factor, the contextual dimension has more readiness for ideal situation.

In last decades, the skillful planning of land resources has become a major issue for rural development. The development of cultivated areas becomes gradually impossible due to ever increasing population growth and urban development. Fuzzy logic is preferred to Boolean logic for land evaluation, because fuzzy techniques lead to estimate for land use suitability on a continuous scale and can therefore, be more informative than the Boolean technique. The objective of this study is to apply fuzzy set methodology in the context of a decision making process known as the Analytic Hierarchy Process (AHP) to land evaluation for irrigated wheat. The results revealed that the results obtained with fuzzy AHP method are in better agreement (R2=0.911) with the observed yield as compared to those obtained with parametric method (R2=0.804). Although, the fuzzy AHP provided more efficient and accurate results than parametric method, the choice of membership functions, width of the transition zones and weight values are determinant to achieve its realistic results in land suitability assessment.

Sustainability creates solutions that solve the economic, social and environmental challenges. It has been studied and managed over many scales of time and space and in many contexts. The paper reviews the definitions of sustainability respecting the ecologic concept as well the need for balanced sustainability within its three pillars on equal way, then it goes throw Ecologic Architecture with its core requirements and how it’s important to work within the framework of Ecologic Architecture. In the aftermath of climate changes there has been an increase of overall interest in sustainability of Environment material. Sustainable development in living environment is not only a trend. Similarly sustainable development in modern bathroom is not a fad. Contemporary societies are not able to function without water, energy, heat, electricity and fuel. It is obvious that the precious natural resources are not available in unlimited quantities. Therefore is absolutely no alternative to necessity of sustainable development. Man must learn to be more careful with using of natural resources; in this paper describe the Livable eco- architecture that have been explained the interaction between sustainable house and urban conditions in analytical approach.
