character of the formation of cities
Studies related to the study of trends and the extent of redistribution of urban growth, their economic profile, the impact of these redeployments on the structural organization of planning and communication of settlement, actively carried out in the U.S.. Particular attention should explore opportunities to regulate urban development that can be solved with the help of cost-oriented concepts, due to the formation of qualitatively new urban phenomena as mega-cities. There is increasing recognition point of view according to which Megalopolis is an integral functional-planning education and regulate its development is only possible by controlling them as a unified whole. Thus, the parameters and nature of the formation of cities, especially large ones, over time, may become increasingly dependent on obschemegalopolisnyh objectives and strategies of socio-economic and urban development.
Considering the folding now mega-cities around the globe, experts determine their minimum value of 25 million people. In the world there are six such mega-cities: the Northeast and Great Lakes in America, the Tokaido in Japan, South Britain, in the north-western Europe (between Amsterdam and the Ruhr industrial area of вЂ‹вЂ‹northern France) and poorly researched Megalopolis in the Shanghai-Nanjing China.
Reduction in the maximum population of mega-cities, for example, up to 10 million people, as suggested in several works, would, according to experts, the loss of a number of specific properties that characterize the Megalopolis compared to agglomerations and other clusters of settlements. Then, as the mega-cities could be seen many monocentric urban agglomerations with a population of about 10 million people. At the same time could be justified in breaking the larger urban systems, and consideration of the individual parts of them as independent urban units. Thus, the Greater New York as well as London, Tokyo-Yokohama and others, could also be treated as separate mega-cities.
