Assessment and Evaluation the Spatial Structure and Urban Creep (Case Study: Yazd City)

Abstract

Abstract The growth of the city as a dual process of spatial and physical development. Each of these two methods can be different and separate from the body of another cause. The urban population growth, urbanization and increased attention to urban issues for urban planners and personnel is essential. This research is descriptive and analytical the subject is discussed. To study the subject in statistical methods Holdern and Shannon entropy analysis of the distribution and density of the urban population has been used in different periods in order to analyze the and mapping of the software GIS, SPSS, Grafer and Excel use. The results show that the basic structure of city of Yazd in the northern part of the neighborhood has been Fahadan. Space systems are not organized grouping of cities and urban spaces on the first floor and top floor, there is no point matrix Even with the entropy index, Yazd province in the years 1996-2011 shows that the balance of cities in the urban middle classes, so that the entropy index has fluctuated in 1996 (-0.37) and in 2011 (-0.23) is obtained. Finally, the model was determined Holdern. The city is only 8/54 of the growth in population growth between the years 1966 to 2006 and 45% of physical development and physical growth of the city.
