In this study texture and variance information are used in some cases but extraction of data from variorum is less carried out and its time changes has not been noticed enough. Multitemporal satellite images of SPOT and ASTER are used in this study for mapping land use/cover of Dehgolan in Kordestan region. The extracted set of indices from variorum is introduced and a new series of indices was extracted and classified by using SVM method. The whole process was accomplished in two stages: 1) classification of spectral band, 2) classification of spectral band along with the parameters extracted from the variorum. After accuracy assessment and their comparison, appropriate indices were suggested. Some indices increase the accuracy of most classes while may have no impact on other classes; these can be considered public indices. Moreover, some indices which are called included specialty indices increase the accuracy of some classes and reduce the accuracy of others. The performed studies, demonstrated that using the indices derived from variorum increases the overall accuracy by 4 to 9 percent in some classes and the overall accuracy is enhanced from 88.98% to 92.744%.

Importance of the environmental quality for other aspects of life, the specific nature of residential environments, the increasing role of urban residential environments as the main habitat of humans, and the numberof people adversely affected by the prevailing condition of their urban residential environment, explained the necessity of investigation of urban environmental quality. This paper has been designated with the goal of assessing the urban environmental quality and presenting a pattern in order to assess environmental quality and recognize the influential criteria. This research tries to describe and explain the concept of environmental quality, as well as examines the influential criteria and their assessment in urban environments. The basis for assessment of environmental quality in Hashtgerd new town is satisfaction index of urban environmental quality from the habitant's viewpoints. The methodology of the assessing the urban quality is set upon the multi-attribute decision methods (Confirmatory Factorial Analysis Method), and also the used model is upon the exiting experiences and the case study of Hashtgerd new town. Based on research findings, new town Hashtgerd's urban environmental quality from the habitants’ viewpoints is in a low level. OF course, conditions in two levels of 1) urban environmental quality and 2) habitat environmental quality of new town Hashtgerd are different, so that, habitat environmental quality in Hashtgerd new town is better than the urban environmental quality. Also, Examination of different attributes shows that only satisfaction of access and roads network, home size, home facilities and current costs attributes exist.

Oil-based cities appeared and started to develop by oil exploration, and development relied on oil exportation, made them modern and wealthy cities, but by terminating of this non-revival resource, downfall part of life cycle of these cities, commence. Masjed Soleyman is a best sample of these cities that was a modern city with sufficient infrastructures in national scale, but by terminating of oil-resources, socio-economical aspect of city has been faced with many different problems. Therefore it is necessary to take economic sustainability of Oil-based cities into consideration and create a multi-purpose economy based on appropriate approach and urban development pattern. The main goal in this paper is to formulate optimum strategies to create variety of alternatives for the economy of sample city in the case study (Dogonbadan). This goal is set up in regards of urban sustainable development vision and based of strategic approach. The other purposes of current paper include literature development in the field of resource-based cities (especially oil-based cities) and formulating quantitative strategies and guidelines for urban planners and managers of these cities. Research methodology in this study is compilation of quantitative and qualitative methods and research has been done by profound interview, document studies and making strategic factors quantitative. Research process includes 5 steps; step 1: after data collection, the research team classifies them for using in next step; step 2: profound interviews are done with experts, managers in oil section and municipal section and experienced planners in organizations in Dogonbadan; step 3: SWOT (Strength, Weakness, Opportunity and Threat) matrix formulated by collecting data through interviews and documents studies and evaluated by analysis model; step 4: after determining the best strategies for the city, strategies converted to quantitative forms by QSPM Matrix; And finally, step 5: strategies for urban sustainable development in the city of Dogonbadan ranked. The result shows that Dogonbadan faces with strategic challenges between costs and benefits. Nevertheless the city encounters with weaknesses and threats, it has strengths and opportunities for sustainable urban development. Sustainable urban development in this city cannot be done unless by using its opportunities and taking an appropriate approach to urban planning and management. So it is necessary for Dogonbadan to take opportunities and decline the threats.

One of the important aspects of sustainable development is directing and determining the physical growth of a city. As regards the lands around cities, especially in Iran, are considered as support environments. A significant proportion of Iranian cities have been located in agricultural hinterlands, therefore it is important to determine the direction of physical growth of the cities with the least damages to agricultural land. Considering other parameters like faults and the geological structure, wind, water levels is essential in environmental planning literature. The aims of this article are to review and determine the best physical growth direction of Babolsar city based on natural parameters such as underground water levels, faults and geological structure, land, wind, and waterways ranges. To determine the optimum physical growth direction of Babolsar the AHP and ELECTRE method has been used. Based on five indicators, the west, east, south, southeast and southwest vectorial have been studied. According to the paper results, the eastern and western vectorial have the highest priority to direct physical growth of Babolsar city.

One of the most important inheritances of climate quaternary is glacier geomorphology evidence in Iran. Identifying and demarcation of glacial landforms in highlands are the best evidences to recognize morphoclimatic and morphodynamic territories. The study aimed to determine the morphoclimatic and morphodynamic zones in the last glacier period and current boundaries in the Jajroud basin, and compare results with previous theories. Hence, by using satellite imageries, topographic maps, GIS geology software and field observations, the locations of cirques were identified and then by using Peltier method morphoclimatic and morphodynamic boundaries in quaternary, were determined. Method and data used in this study were mainly obtained from topographic maps, geology, satellite images, climate data temperature and monthly precipitation. Results show that low level of glacier areas already existed at height of 5220 meter, and levels of solifluction, pluvial and pediment are at 4000 meter height, fluvial at, 3400 meter, and pediment at 1565 meter respectively. Also in the last glacier period, the lowest level of glacial was respectively at 3900 meter, Solifluction at 3000 meter, and fluvial at 2000 meter. The results show that morphodynamic and morphoclimatic levels were higher than former results attained by "Alborz Mountain researches".

One of the issues that nowadays urban and rural settlements are faced with is inappropriate distribution of social services and facilities that cause inequality in access rate of different groups to that facilities and services. This paper by considering this social challenge which resulted from poor development management, pursue the status of people enjoyment by considering three levels of political division of east Azerbaijan province including city, county, rural district, and determine investment priorities by recognizing deprived city, county, rural districts and offer strategies and policies to make appropriate access. Research method and analyses technique is factor analyses and numerical taxonomy. 28 indicators have been defined in different dimensions to classify different levels. The results show high rate of deprivation in northeast and southeast of the province, and the rural districts that have facilities are mainly located around southwest and middle zone of the province. Analysis shows the eastern half of province has more deprivation than western half of the province. It’s necessary that development managers of the province give priority to investment in cities, rural district in eastern half of the province. The study also shows significant direct relationship (99%) between center distance rate of each political division to province center and deprivation rate. By increasing distance from province center, the deprivation rate increases.

Geographical study of Iran and feasibility of economic investment and opportunities in free trade zones, indicate that these zones can be regarded as exceptional investable economic resources. Hence this study considers the industrial, commercial and tourism potentials of Aras free zone, adopting a regional developmental approach by using descriptive-analytical method. Results show that Aras free zone enjoys comprehensive regional development potential because of its geostrategic position, neighboring C.I.S countries, being locating in international transportation corridors (6 corridors) as well as the Silk Road, the closest zone to Turkey as the Europe gateway, having capability of serving as the shortest road and rail link between Iran and other Persian Gulf countries, having Aras river as a natural link, enjoying the support of the metropolis of Tabriz, tourist attractions, etc.
