The administrative centers of rayons (county-type civil divisions) are viewed as key elements in the provision of services in the USSR. The effectiveness of rayon seats as service centers is analyzed in terms of the category of places serving as rayon seats (small cities; urban-type settlements [towns]; rural places), mean rayon population, area and radius, and the mean transport accessibility of the rayon center. The existence of a small city with a high level of services in a small rayon, as in the Baltic region, Belorussia, Moldavia and parts of the Ukraine, is viewed as optimal. Particular problems arise in Siberia and Kazakhstan, where the large size of rayons, low mean rayon population, big rayon radius and low transport accessibility combine to produce a low level of services. In such regions, a system of local service centers is advocated, with rayon seats performing the role of major regional centers.  相似文献

Population changes in Cuba are analyzed on the basis of differential growth rates in provinces and urban centers. Three types of areas are distinguished: (1) those where population continues to be concentrated as a result of high growth rates exceeding the national average (notably major industrial towns and ports and rapidly developing agricultural areas); (2) areas recording absolute population increases, but at lower rates of growth than the national average; (3) areas in which population is declining.  相似文献

ABSTRACT. The paper is devoted to modeling the relationship between the density of service centers and the density of population (or on the density of demand). Several models lead to an exponential function with the exponent equal to ⅔. For a number of real systems of centers, the power is considerably different from ⅔ (more often it is nearer to 1). I describe a series of models that explain this difference.  相似文献

This article tests a model for the political economy of the Wari Empire (AD 600–1000) of Peru. This model divides the empire into core and periphery zones. In the core, Wari political economy was organized to extract surplus agricultural production to feed the capital. In the periphery, the Wari strove to extract prestige goods. We suggest that there is a strong relationship between where the empire chose to locate its centers in the periphery and the political complexity of the local population in which the center was placed. We argue that in areas of low political organization sites should be located near the geographic center of a population. These sites will tend to function as local administrative centers geared toward the organization and exploitation of the area's wealth potential. In areas with more complex political organization sites should be located on the margins of a population. These sites should have functioned as gateway centers controlling, or at least profiting from, interregional exchange. Our model was systematically tested through the use of Geographic Information Systems (GIS). The results suggest that much of the variability found in Wari site placement in the periphery can be explained by differences in local sociopolitical complexity.  相似文献

A government official outlines some of the Soviet problems of settlement to which answers are expected from population geographers. They include: restrictions on excessive growth of large cities; promotion of industrial plant location in small and medium-size cities suffering from underemployment; prediction of ultimate population of large cities; determination of the optimal size and type of rural population centers. Population geographers are called upon to study large cities with a view to determining where further concentration of industry should be prohibited, and to select small cities suitable for plant location.  相似文献

Simple arithmetical formulas are proposed for the study and analysis of urbanization processes. The formulas establish functional relationships between the urbanization level at the beginning of a particular study period, the changes in urban and rural population during the period, and the urbanization level at the end of the period. The relative share of administrative centers and of other urban places in a particular major civil division in total urban population is also considered. Different types of urbanization processes are discussed and plotted on a graphic-analytical model (nomogram). Contrary to general assumption, it is found that in the USSR it is not the very large cities (500,000 and over) that are increasingly concentrating urban population, but the next lowest size class (100,000–500,000). Further research into urbanization processes in particular spatial settlement systems is urged.  相似文献

Between the 13th and 11th centuries BCE, most Greek Bronze Age Palatial centers were destroyed and/or abandoned. The following centuries were typified by low population levels. Data from oxygen-isotope speleothems, stable carbon isotopes, alkenone-derived sea surface temperatures, and changes in warm-species dinocysts and formanifera in the Mediterranean indicate that the Early Iron Age was more arid than the preceding Bronze Age. A sharp increase in Northern Hemisphere temperatures preceded the collapse of Palatial centers, a sharp decrease occurred during their abandonment. Mediterranean Sea surface temperatures cooled rapidly during the Late Bronze Age, limiting freshwater flux into the atmosphere and thus reducing precipitation over land. These climatic changes could have affected Palatial centers that were dependent upon high levels of agricultural productivity. Declines in agricultural production would have made higher-density populations in Palatial centers unsustainable. The ‘Greek Dark Ages’ that followed occurred during prolonged arid conditions that lasted until the Roman Warm Period.  相似文献

A methodology in described to forecast the “passenger intensity” of population centers and economic regions or subregions, expressed as the ratio of passenger departures to total population. Intra-regional passenger intensity in found to be closely related to income levels and to availability of a transport net. A greater complexity of factors dictates the passenger-forming role of economic regions in inter-regional traffic.  相似文献

In the absence of Soviet census data on processes of formation of urban population, the author analyzes the origins of industrial workers in four urban centers of Moscow Oblast. He finds that the extent of the labor-supply area depends on the availability of local labor, the character of the skills required, the traditional occupations and work skills of the population, and certain aspects of a planned economy, such as the compulsory assignment of graduates to specific jobs and areas.  相似文献

Abstract

This article aims at distinguishing recurrent population movements within the territory of the Russian Federation between urban localities of different sizes and rural areas in connection to the processes of urbanization, suburbanization, and de-urbanization. Incomplete urbanization and the strong polarization of socio-economic space in Russia have resulted in two powerful contradictory population flows: centrifugal seasonal sub- and de-urbanization and centripetal labor migration from rural and small towns to large urban centers. The article discusses three forms of recurrent population mobility in Russia: (1) daily commuting of urban and rural inhabitants within metropolitan areas; (2) commuting to large cities and their suburbs for long-term employment intervals (weekly, monthly, etc.), (3) second-home commuting to countryside dachas. Unfinished urbanization in Russia not only attracts rural and small towns’ population to major cities but also keeps it within the latter. It slows down the real de-urbanization and induces specific dachas (second-home) suburbanization/de-urbanization, with these processes being closely interrelated. An opportunity to earn money in cities together with the impossibility of moving to major centers due to expensive housing encourages households to remain in small towns and rural areas. Meanwhile, inhabited rural localities (even ones distant from cities) attract seasonal population (dachniks).  相似文献

A model is developed in which the change in the population distribution of a region is linked to the employment pattern, and this latter in turn to the population distribution through the concepts of central place theory. The result is a dynamic model of interacting urban centers in which the fluctuations (the exact history) of the system play a vital role, and with which the effect of an infrastructure decision can be estimated in the long term.  相似文献

ABSTRACT. Within the framework of an existing hierarchy of shopping centers, Voronoi diagrams at each level of the hierarchy are used to define infringement on existing centers by new entrants. We distinguish four intensities of infringement—that is, four categorizations of when existing centers face new competition—and label shopping centers accordingly. Our aim is to determine empirically which type of new competition is best explained by various attributes of the incumbent centers. To accomplish this, logit analysis is used to relate the above labels to market-area population, store turnover, age, and hierarchical level of each shopping center in Edmonton, Alberta.  相似文献

A comparison of United States topographic maps with the actual terrain shows a disregard of geographical differences in the use of vegetation symbols, contour lines and population centers. This is attributed to the fact that topographic technicians lack a geographic background. The county soil surveys of the United States evoke a great deal of admiration and praise, but the lack of a uniform soil classification enabling the compilation of generalized soil maps is deplored.  相似文献

Novgorod Oblast, in northwestern Russia, has been distinguished by a high rate of rural outmigration and depletion of agricultural labor resources. One key factor in slowing the flight from the land is an improvement in the quality and range of rural services. The impact of adequate services is shown by available data on the distribution of rural population by distance from service centers. The rate of decline of rural population is generally found to be lower in places near service centers than in more remote places. Since most of the rural places are too small to support service establishments, it is recommended that services be expanded in about 200 central places that show promise of future growth.  相似文献

A variety of approaches are being recommended in regional plans for future settlements patterns in the Soviet Far East. In Magadan Oblast, the present scattered pattern of small populated places is to be superseded by greater concentration of urban population in a set of subregional service centers. In Khabarovsk Kray, different approaches are being recommended for the future development of the Khabarovsk and Komsomol'sk areas. Because limitation of the future growth of Khabarovsk is desirable, new industrial establishments are to be located in the future in nearby small towns and urban settlements of the Khabarovsk industrial district. In the Komsomol'sk area, satellite towns are to be significantly developed, giving rise to a grouped form of urban settlement, including the tin-mining center of Solnechnyy and the paper and chemical center of Amursk. In Amur Oblast, consideration is being given to the development of an iron and steel plant in the Svobodnyy area, giving rise to a city of up to 200,000 population.  相似文献

While many works have examined urban mortality rates in nineteenth-century Europe, much less attention has been placed on disease patterns in the peripheral areas surrounding these population centers. This study demonstrates that during the Swedish diphtheria epidemic of the early 1880s, mortality rates among children living in the industrial parishes on the outskirts of the town of Sundsvall exceeded those found in the town itself. The epidemic was fueled by the mass in-migration of laborers and their families from distant provinces who sought work in the region's sawmills. Thus, in contrast to the common pattern of disease entering through a port city and spreading into the interior, in this case diphtheria followed the paths of migrants through the rural parishes of the Sundsvall region to the sawmills and then finally into the town itself. This spatial pattern was reversed in the late fall when migrants returned home. Conflicts within the medical profession regarding how best to prevent or contain diphtheria, popular suspicion and distrust of local physicians, and the introduction of the disease into a population with no prior contact with it, all helped increase the number of young corpses.  相似文献
