Social and economic inequalities in the world today affecting the differences of geographical, spatial patterns of crowds to create special activities that affect the development of data. The spatial distribution of population and activities in the field of formed networks of settlement, which are listed due to the differences in the resources available to it, the game development a key role. In this context, the main objective of this thesis is to investigate the role of urban network on regional development in different environments, coastal and mountainous. In this paper, according to the study (cross-sectional) of two groups of; research techniques (regression analysis, graphical techniques, and indicates math) and specialized techniques (index primary city, rank-size model, the rank-size adjustment model, the model of breaking-point and the model of urbanization and employment) is used. In this research, the urban network in the Zagros region and the northern coast of connection with nature, this region has been analyzed, and the urban network in different regions of the prime indicators of urban population in this network were analyzed. To determine the regional development of different regions, economic sectors and L.Q as urbanization, urban networks of these regions were compared with each other. After determining the type of regional development, functional poles of zones of influence and urbanization and economic regression analysis was performed. The last step proportion of regional of urban network of network Zagros region and the northern coast by Ranke-size model, the rank-size adjustment model and entropy index in the demographic categories this region for providing a model of urban networks that facilitate regional development in these regions, was determined. In general, the hypothesis test, the important role of regional networks in mountainous regions and coastal city in terms of how the use of resources (human and natural) for the analyzes, and urban networks in regions where resources were concentrated in a small space like a shoreline, low impact on regional development knows, for cities of network in the coastlines of shared resources they consume. But the networks of cities in mountainous regions due to natural features and greater dispersion of resources, each with their own resources. That s why urban network in mountain region can have more power and have more impact on the regional development of regions.Social and economic inequalities in the world today affecting the differences of geographical, spatial patterns of crowds to create special activities that affect the development of data.
