Nowadays, unbalancing and inequality of spaces among urban and rural settlements are important subjects of economists and regional programmers. Existing economical divergence, development poles and dispersion of rural regions are the effects of this phenomenon.
So accessing to balance and consistent expansion in regional space, establishing regular and ordered sequences are major needs and pay attention to small towns is one of the ways to equilibration this situation.
This study has done to recognition the disposition pattern of residents, quality of centralization and population distribution in Yazd during 1966 to 2006. At first urban centralization models for measurement the population centralization in residents net and population elasticity model for determining importance of small towns in regional balancing are used. Then for recognition the quality of village dispersion and determining their centrality, the model of analyzing the nearest proximity, feature model and the Interaction Theory were used.
According to results, the rate of population centralization in urban network in 2006 was about 3.7 and showed polar dispersion in Yazd. Where as in the same year, only 20 percent of Yazd population lived in 1390 villages. Among them, only 30 percent had population more than 20 families. Settlemet pattern of these residents is clustery with definite spaces according to computations of the nearest proximity (0.73) leveling of rural spaces and determination of their centralization has done according to quality of dispersion and their size in region. 69 rural centers in small spaces of village and 13 small towns have connector role among rural levels and massive urban levels (urban network). Finally, suggestions are presented for balance dispersion of Yazd especially coordinated dispersion of urban network with rural network.
