The...Urbanization is a complex process that covers a wide range of topics, of which population, industry and land urbanization are three important aspects. Jilin Province is an important agricultural province in China. The contradiction between population, industry and land urbanization is especially prominent here, and its coupling development is of great practical significance. In this paper, the coupling degree of population-industry-land urbanization in Jilin Province in 1990, 2000 and 2010 is measured by coupling mode. The spatial pattern of the coupling degree is analyzed by trend surface analysis and global and local spatial autocorrelation. The influence factors and their spatial differentiation are discussed using multiple linear regression(MLR) model and geographic weighted regression(GWR) model. The results show that: 1) the coupling degree of population-industry-land urbanization in Jilin Province is at a low level. Judging from the change of time scale, the urbanization of most research units is becoming more and more coordinated. From the comparison of spatial scales, there is significant spatial difference in the research units of different administrative levels. 2) Judging from the global change trend, the coupling degree of population-industry-land urbanization in the central region is higher than that in western and eastern regions. The coordination of urbanization in the central region is relatively good, and the distribution of the cold and hot spots is basically the same as that overall. 3) The spatial pattern of the coupling degree is related to the cold and hot spot distribution of the influence coefficient of urban population density and per capita urban construction land. The variation of the coupling degree spatial pattern is synchronous with the spatial change of the urban population density influence coefficient. 4) The degree of agglomeration of the urban population is the main factor promoting the coupling pattern of population-industry-land urbanization in Jilin Province, and the extent of its influence is gradually increasing. In addition, the level of city administrative, the efficiency of urban expansion and the capacity of market consumption also have an important influence on the coupling pattern.展开更多

It was carried out by Benito Mussolini, called II Duce, who governed Italy by a regime with an absolute and conservative approach for 20 years since 1922. According to this plan, there were some rural villages (with a school, a church, a police station and a doctor's surgery) and a number of rural homes, spread in the landscape, that formed one of the most important achievements of the agrarian reform in Italy. The author has been conducting scientific research on this topic for several years. He started with the archive "Ente per la Colonizzazione del Latifondo Siciliano" (now called Ente Sviluppo Agricolo) to review the original designs and contracts with companies, ledgers and other administrative documents. Lately, he has been reviewing the personal archives of designers involved in the building program, where he has found original drawings, letters, sketches, etc.. He has also conducted some architectonic and technical surveys of the sites. We have to consider that nowadays the mentioned rural villages are a strategic resource for the development of the neighboring areas, as it may become a network for the sustainable tourism and the promotion of the local agro food specialties. On this purpose, the local authority is going to promote some plans for the requalification of these sites. The particular achievement of this article is to show a number of possibilities for the reuse of these places.展开更多

We trace its gradual evolvement from a backwater town into a 21th century capital to piece the picture of our town together from separate puzzles in names and events. The history of our town with its colonial, soviet and post-soviet periods is impetuously losing its two original contexts. The new city was not built anew, from scratch, but was further constructed, extended and novelized. However the first two periods are effaced and pushed to the background, becoming an apophasis. The questions to puzzle out are: Why the town was renamed so many times into Akmolinsk, Tselinograd, Akmola, and Astana; why it had a few emblems on its record; and from which year starts settlement of the territory this modern city currently takes up. Then comes another moot point: How many times was our town's status put to question? Of special interest is street renaming and monuments' relocation and the town's demographic constituent is no less a serious subject of research. Our town formed through permanent movement of the rural population to it, which concurred with the governmental campaigns in the epoch in question. Urban environment certainly told on inter-relations, and brought about problems. One of them is the problem of tolerance, inevitably arising in any big city. The problem of misunderstanding between the residents of former Tselinograd and present Astana is generation gap. For permanent population's rotation practically no urban life traditions have taken on a definite shape among majority of the residents, paradoxical as it is. The population's intent to cast off all the colonial and soviet past ended in the loss of representative opportunities of the "old" town.展开更多

Recently, super-aging in old suburbs is remarkable. Recently, Japanese old suburban housing estates are declining. They are facing several serious problems. Most serious problems are aging of residents and decreasing population, and these are caused by long-term dwelling. Because many Japanese think that "Japanese Dream" is occupancy of detached house in suburb. Japanese suburban residents tend to stay after child rearing. And another severe problem is the increasing vacant houses. In this study, the authors try to clarify the conditions of shrinking suburbs in Japanese cities and will introduce some activities for revitalization in suburbs. As for aging of suburban residents, in old housing estates, the first generation of migrants grew older and continued to live in their own house in suburban areas. Furthermore, their children grew up and moved out. These are caused by the failure of town planning, which supplied the same type of houses in short term. Furthermore, increases in vacant houses are seen throughout every old suburban housing estate, and it induces new uneasiness and social troubles and drop in housing price.展开更多

No casualties have been reported,with only slight damage. The disaster level of this event is the slightest on the M4.9~5.1 events record tally since the CCDSN (China Center of Digital Seismic Network) was built in 1999. The epicenter intensity of this earthquake was low,while in areas like Beijing,which is 100km far away,abnormal high intensity zones appeared. This article discusses the reasons behind this abnormal phenomenon,with the diagrams of intensity isolines drawn by the intense seismic stations and networks in the capital circle area as references,as well as the seismogenic mechanism in the source,the seismic histories,the geological structures and the ray pathways of seismic waves in areas within 150km around the epicenter. It was concluded that the special dynamic and geological situations were the main causes for the lower intensity degree and slight damage in the epicenter area,but higher intensity in the surrounding areas.展开更多

But it is especially a city that currently polarizes a huge interest from public authorities, researchers, as well as citizens represented by associations that are militating to safeguard and promote the city. Making Constantine "a regional capital, a metropolis" is the ambitious urban project of this city authorities. It is a prestigious project, but at the same time, a double-edged sword. With the emergence of this project, a new conception of the city and its image is induced, the one that conjures new canons of urban modernity, with the whole discourse that sustains it and indicators that materialize it. A new attitude toward the current city of Constantine has emerged, from both the authorities and citizens. The inhabitants are continuing in spite of all to invest their city and do not accept that the natural process of appropriation of space may be stopped indefinitely. The author will try to expose the conflict situationof a changing city inside numerous and varied issues, as well as stakes and challenges.展开更多

Based on field research conducted intermittently between 1999 and 2007, it probes the local grounding of the ongoing place-making processes in terms of the "lower/higher quarter" dichotomy reminiscent of Shanghai's semi--colonial past and the apparent contradictions in the politics of planning. By way of mapping "Shanghai nostalgia" in time and space, attempts are made to locate the cultural symbols in actual sites so that upper quarters and lower quarters as imagined communities come to be attached to imagined places. From the intimate perspectives provided by ethnographic fieldwork, the author explores the significance of locality power embedded in the dichotomy-the ways in which it is exploited, the memories to which it is linked, and more importantly, the explanations it provides for present-day reconfigurations of social space and redistributions of cultural resource in China's most cosmopolitan city.展开更多

The results reveal the following: First, in 2015, the majority of Belt and Road countries in Europe, South Asia and Southeast Asia had high population densities, whereas most countries in Central Asia, North Africa and West Asia, as well as Russia and Mongolia, had low population densities; the majority of countries in South Asia, Southeast Asia, Central Asia, West Asia and North Africa had rapid population growth, whereas many countries in Europe had negative population growth; and five Belt and Road countries are in the initial stage of urbanization, 44 countries are in the acceleration stage of urbanization, and 26 are in the terminal stage of urbanization. Second, in the century from 1950 to 2050, the mean center of the study area's population is consistently located in the border region between India and China. Prior to 2000, the trajectory of the mean center was from northwest to southeast, but from 2000 it is on a southward trajectory, as the population of the study area becomes more concentrated. Future population growth hotspots are predicted to be in South Asia, West Asia and Southeast Asia, and hotspot countries for the period 2015-2030 include India, China, Pakistan and Indonesia, though China will move into nega- tive population growth after 2030. Third, the overall urban population of Belt and Road coun- tries increased from 22% in 1950 to 49% in 2015, and it is expected to gradually catch up with the world average, reaching 64% in 2050. The different levels of urbanization in different countries display significant spatial dependency, and in the hundred-year period under con-sideration, this dependency increases before eventually weakening. Fourth, between 2015 and 2030, urban population hotspots will include Thailand, China, Laos and Albania, while Kuwait, Cyprus, Qatar and Estonia will be urban "coldspots." Fifth, there were 293 cities with populations over 1 million located along the Belt and Road in 2015, but that number Js ex- pected to increase to 377 by 2030. Of those, 43 will be in China, with many of the others located in India, Indonesia and the eastern Mediterranean.展开更多
