| Abstract | ||
| Urban systems exposed to dynamics continuously by the effect of external and internal factors. This appears through urban growth of these systems, their elements and their relationships. Dynamics is the main concept for understanding the continuity and survival of urban systems , which show type of random behavior. It expresses structural and morphological changes within cities, to reach a state of balance and self – regulation. So there is a need to understand the city as dynamics system. This system swinging ,as a result of tension, which is caused by emergence and decay of cities. So research problem is that, "there is no obvious image about the role of emergence in the dynamics of urban growth". The paper aims to study the local urban system, and to discover its dynamics behavior, which is caused by the effect of external and internal factors. The research hypothesis is that "the city growth dynamically by the effect of emergence of new urban agglomerations, the degree of emergence of these agglomerations in one dynamics level (whither it is micro or macro) depend on the relation ship between urban dynamic and population size over time". This paper study, on macro level, the Iraqi urban system (the eighteen provinces), as well as, (Najaf city) on micro level, between (1947-2007). The research findings was that the Iraqi urban system, changes its spatial behavior each (5.4) year during the above mentioned period. There was three types of cities, the main cities, the religious one, and those which are emerged by political decisions, and are differed in their urban growth style. The research found that Najaf city grows gradually, with a state of un –regularity on micro level. The large cities enter within the urban system and moved toward the center, while the small cities moved toward the periphery and latter on toward the center over time. | ||
