During the past two centuries, the world has rapidly become urban. The most important aspects and outcomes of this process is spatial development and physical extension of cities towards rural areas which is done through the joining of villages with cities and transferring rural centers into small towns. Although small cities start with a small population and range, but they rapidly take agricultural lands and rural areas. During the second half of the twentieth century, this process begun and quickly spread the number of cities, added to the urban population and many villages were converted to cities. During recent decade, the fast process of the conversion of villages into cities, resulted in the change of agricultural land use and the natural regional perspectives were degraded, although it was done with the aim of profiting rural from urban services, but in areas such as the Caspian plain; especially in cases where newly established cities are a combination of villages, the remaining population which is a range of low density, non-uniform and porous will be filled in the near future with constructions and urban instruments! To prevent this stressful process, the conversion program of centers into small rural cities can not be entirely taken for granted; but it should be considered in developing cities such as spatial and functional patterns suiting the development area. In the Caspian region, for example, tourism capabilities of rural areas could be activated, in addition to preserving agricultural lands and rural perspectives and taking use of the profits of urban services and facilities through the garden-city model.
