Social patterns in open space organizations have a key role in shaping most of 20th urban theories. This paper identifies the formal and social patterns in planning the residential open spaces in famous theories and projects of urbanization during 20th century and compares them with experiences of Iranian urban organizations in an analytic manner from the past to present. Historical – interpretative method established in this research was combined with case studies. From the formal viewpoint in the early 20th century theories, 4 categories of open space organizations could be identified: "grid organization", "linear", "central" and "complex" patterns, which have been tended towards complex patterns during the second half of the century. Moreover, try to remove social hierarchy, providing class equality and common ownership of open spaces seen in the first half of the century has been replaced by social stability, social equality and simultaneous attention to both public and private open spaces. However, the modern construction in country is almost the continuation of the early century proven strategies that mainly use the central and grid patterns and lack of certain social patterns in their designs. Hence, considering current world conditions and national experiences and achievements and belief principles, it is suggested to pay attention to the social concepts like social capital social interaction along with suitable patterns of open space organization (for example, complex) while particular separating and dividing public-private fields and measuring public priorities.

Natural tourism planning is the first step in tourism approach natural resource management in which prone areas for recreational planning is zoned. Aimed to identify the different forms of tourism zoning in Abidar natural forest park in Sanandaj City, a systematic analysis method was used. We produced a recreational potential map using systematic analysis model in GIS. The results of this evaluation indicated that the study area lacks first class concentrated recreation potentiality and the maximum surface area of the study area has been consisted of the second class potentiality. To evaluate the impact of factors affecting tourists, 450 questionnaires were distributed among the tourists. The survey results indicated that most tourists have selected the area because of the access to water resources. The buffer map of water resource was prepared to promote the systematic analysis model and to assess the effect of water resources on different recreation classes of the model and it was integrated into a recreational potentiality map of system model and the final map of the recreational potentiality was prepared. The evaluation results showed that 6% of the area has first class concentrated recreational potentiality, 28 percent of the area has second class concentrated recreational potentiality, 35 percent of the area has first class discrete recreational potentiality, and the rest 31% of the area has second class discrete recreational potentiality. Comparing two recreation potentiality maps showed hat in systematic analysis model, the region does not have first class concentrated recreation place. However, scoring the water resources factor made 6% of the region earn first class concentrated recreation potentiality. The results of this survey indicated that water resources, herbal coverage, accessibility ways, and physical factors (gradient and direction) have the most effect on the evaluation process of recreation potentiality in the region as they are mentioned in order of effectiveness. While the effective parameters in recreation potentiality evaluation in systematic analysis model are gradient, soil, direction, water, plant, and climate. Based on our findings, it was found that recreational activities expected in broad zones include things like walking, trekking, visiting landscapes and snow skating, etc., which do not need to deploy and service of recreational trails, except in designing walking routes in certain circumstances. But, in areas having concentrated recreation zone, activities such as camping, family picnics, etc., require suitable facilities for establishment of tourism.

In this methodology, sampling was done in subjective and snowball manner, and coding method was used for analyzing results obtained. Our results showed that there is no possibility for comprehensive and complete assigning environment management to municipality. However, on the other hand, the abovementioned management duties can be assigned to municipality in a relative manner, and environmental management can be done in integrated cooperation with other related organizations. Moreover, it requires some capacities be made in three structural, lawful, and cultural scopes in municipality organization in order to make municipality able in doing assigned duties.

Supply of suitable housing depends on market conditions, demand rate for it and government policies for allocation of space and facilities. In the worldwide, housing is an important determinant of quality of life.

Based on our results and findings, First Plan has considered density of household in housing unit but has not cared about the organizing of informal settlements, worn tissues and increasing of building density. The Second Plan was concerned with worn tissues, increase of density and its main problem was increasing the individual housing. The Third plan has given special attention to low-income groups and its main challenge was paying not enough attention to the relationship between public and private purposes. The Fourth Plan has considered organizing of worn tissues and low-income housing (Mehr housing) that was an effective step towards social justice and supply of housing for low-income households.

The paper tries to describe the role of municipal toll on house price in Mashhad City. The methodology adopted was analytical-descriptive to study the impact of municipality toll with emphasis on the effect of excess density franchising toll on house price. The study area is district 11 of Mashhad municipality zones. The data required were gathered through literature survey, obtaining information from the district municipality, referring to websites and real estate centers, Mashhad City Urban Integrated System website, field works, and sampling. 250 samples were selected and analyzed using linear regression model through SPSS (Version 18). Our findings indicated that surplus density tax increases the price of new houses through increasing the cost of housing by 10 percent. Pearson correlation coefficient (r = 0.882) confirms that there is a positive and significant relation between price of new houses and surplus density tax. Therefore, it is proposed that the revenue system of municipality be based on stable financial resources. Moreover, it is necessary to reduce the tax on house construction and mutually the tax on house taking should be raised.

According to the world tourism organization, tourism industry is one of the most important economic activities around the world. Although world tourism industry has grown considerably compared with other industries, but nowadays it is faced different touristic region competition. The objective of this study was to evaluate the attractiveness and competitiveness of Mashhad Koohsangi Touristic Park using Tourism Destination Competitiveness and Attractiveness (TDCA) model. This park has many historical and cultural heritages, where many recreational facilities have been established recently. Data required were collected by means of filling questionnaire based on TDCA model. 241 tourists were randomly selected suring September 2009 as the sample population. Validity of data was confirmed by Chronbakh alpha value, which was 0.88. Data collected were analyzed based on the model using linear regression. Our findings shows that the area has suitable conditions from the viewpoint of attractiveness but it is faced with lack of competitiveness, which is the result of low attention to this issue in tourism planning in the area. It is obvious that authorities are not so free providing more attractive services to increase the competitiveness of site. They are faced to some limitations due to urban and residential situation of site. Therefore, at the moment in addition to the protection of existing attractiveness, applying incentive factors to increase competitiveness of area is the central requirement of tourism development planning in the area.
