migration and quality of redistribution of population across country is one of the main factors that planners take into account to control population and guide its movements to economic poles. scientific recognition of migration phenomenon is important for managing and policy making in the country. these movements change migration pattern, in a way that along with increase in population and the...
Rural heritage includes architecture and its special landscapes. The architectural structure of rural settlements is the result of a set of human activities related to the natural and cultural environment. The salient illustration of this type of architecture can be founded in local architecture, which is the main element of rural texture. The spatial organization, establishment and physical st...

one of the most visible aspects of a forest stand structure is the spatial patterns of trees. competition affects on forest structure and its understanding is important, when the purpose of forest management is to imitate the dynamic of natural ecosystems. for this purpose, an unmanaged intact forest was selected with 26 hectares area. all chestnut leaf oak (quercus castaneifolia) trees with a ...
spatial organizations of each region are evolved through the activity of its settlement network. the formation procedure of settlement network is affected by the natural environment, social and economical structure, political and historical events. natural environment, social and economical structure of the city of talesh, have not permitted the permanent settlement and urbanism in this region....
Issues related to environment are one of the most important issues that confront communities in recent decades. Resource scarcity and the necessity of development for Iran and other similar countries requires us to deal with carbon dioxide emissions as a manifestation of environmental crisis. In this study, we assess the relationship between carbon dioxide emissions as a dependent variable wi...
The House as a social- cultural unit is the product of the interaction between housing patterns and patterns of human habitation, is expressed in the form of behavioral patterns and physical spatial patterns. The present study seeks to explore how these patterns are embedded in the structure of vernacular houses. Therefore, 15 middle class houses in Ardabil who were left from the late Qajar and...
determining the promising area for ore deposits is one of the most important steps of prospecting in regional scales. there are many different methods for identifying these areas including geochemical and geophysical methods, remote sensing and sophisticated statistical methods. based on the theory of spatial relations between the dispersion pattern of ore deposits and metallogenic provinces, m...
spatial pattern of trees is an important characteristic of plant communities. generating hypotheses relating to the structure of ecological communities is the aim of spatial pattern recognition. stands spatial patterns are measured and mapped by measuring tree locations in the stand and entering each coordinates into analytical frameworks. the spatial pattern of plant populations observed at an...
Assessment of forest structure and their spatial patterns are essential for managing and evaluation of forest ecosystems. This study was conducted at the Zagros forests in Kermanshah to evaluate the forest structural characteristics and their spatial distribution. Data was collected from 25 plots (400 m2) in a 100 m × 100 m systematic sampling grid. The spacing between plots was 50 m. In each p...
