Analyzing the Spatial Expansion Pattern and Causes of Abdanan City

Nowadays the discussion on Physical- Spatial Expansion of cities is one of the problems of developing countries, especially Iran. The growth causes and pattern of a city is the most critical matters of the recent century. So, recognition of spatial growth causes and pattern of main cities of regions and countries such as Abdanan City is necessary for drawing up suitable policies and achieving sustainable development. In this regard, in the framework of sustainable development and urban smart growth theories, the causes and quality of spatial growth pattern of Abdanan City were evaluated in the framework of the analytical-descriptive research method. In this framework, for analyzing the population and employment distribution used Gini and Entropy's indexes. For analyzing the development pattern we used Moran and General G indexes, and Holdren model and Shanon Entropy's. The necessary data was collect by librarian method. The necessary data was collect by librarian method. The results showed that there are imbalance in population and employment distribution. The results also showed that the Abdanan City have had a random development pattern tending to Clustered pattern by forming a hot spot in its south part and a cold spot in its north part and because of low density, the results indicated in the ascendancy of the dispersed pattern. The results showed that Abdanan City despite dispersed growth in most periods, during 1385-1390, have had a sprawl growth of 97 percent and less than 3 percent of that is because of population growth and the real needs of the land. Finally, the results showed that management and economical parameters have high role in growth pattern of Abdanan city.
