A network of 484 economic microregions designed by the Central Urban Planning Institute is used as units of analysis to determine trends in the concentration of population in some parts of the Russian Republic. The analysis is carried out over time and on two levels: the area that contains 50 percent of the total population of the RSFSR, and the area that contains 75 percent of the population. In 1973, at the end of the study period, 50 percent of the population was accommodated in 4.3 percent of the area of the RSFSR, and 75 percent of the population was settled in 11 percent of the area. At the same time, one-fourth of the area of the RSFSR was found to be losing population.  相似文献

Fresh, weathered, archaeological and fossilized bones were subjected to a series of abrasion experiments using fine sand in an annular flume in order to link bone-surface abrasion to flow regimes and sediment transport modes, compare these effects on bones of different states, and quantify the extent and types of wear occurring. Flow velocities were chosen to replicate the predominant transport modes of bedload, saltation and suspension.Comparative scanning electron microscopic image analysis was performed to assess the degree and type of wear occurring on each bone type for the different transport modes over a range of exposure periods from 24 to 72 h.These preliminary investigations have shown that both the amount and type of wear experienced was related to the bone type, duration of exposure and the mode of sediment transport with wear being the result of deformation, rather than cutting wear.The formation of scour pits in the sand bed on the upstream side of the bone samples significantly reduced wear, and appears to be an important control mechanism for impact related wear that has been overlooked until now.  相似文献

Mountain regions represent a substantial part of Soviet territory, a total of 652 million hectares, which is 29.5 percent of the total area, or 21 percent of the usable agricultural area (including livestock range), but only 3.8 percent of the arable land. Soviet policy toward mountain development has varied over time. At first, mountain areas were considered a symbol of backwardness, and were not allocated a role in the Soviet modernization program. In recent decades, attitudes have been changing, but solutions have differed. The author, focusing on the eastern portion of the Greater Caucasus, shows on the basis of the literature and personal observations how the policy in Dagestan and in Azerbaijan, by allocating lowland activities to mountain populations, differs from Georgian policy, which since 1976 has actively sought to foster a revival of mountain economies.  相似文献

An analysis of recreation uses in the Moscow region shows a generalized radial pattern focused on the city of Moscow as the center of demand and an outward diffusion with distance from the city combined with clustering along railroad lines. This overall pattern is deformed by landscape differences, with higher density of recreation use in well drained wooded areas and lower density in swampy areas. The locational patterns of recreational use are further broken down by groups of users.

Starch grains from 31 modern samples of millets derived from the seeds of 7 species within the genus Setaria and 2 species within the genus Panicum were analyzed to determine diagnostic morphological characteristics. Ancient starch grains recovered from a sample of broomcorn millet (Panicum miliaceum) excavated from the Cishan site (10.0-7.6 cal yr BP) in the North China Plain were then subjected to the same analyses to determine the differences in morphologies, if any, between modern and ancient samples. The data indicate that morphological features, and particularly surface and fissure features, will allow for solid identifications of ancient millet starches, while size classes will be helpful, but will not be dependable taxonomic indicators.  相似文献

Past Soviet attempts to define settlement areas have focused either on urban or on rural population areas. An attempt is made here to define combined urban and rural settlement areas, with particular reference to the Northwest Region, centered on Leningrad. A regional settlement area (centered on Leningrad) and a number of local settlement areas, centered on major cities, are differentiated, with so-called zones of disseminated settlement situated outside the limits of the local areas. The local settlement area of Pskov is discussed in detail, with a breakdown into three concentric zones based on the intensity of linkages with the central city.  相似文献

A low rate of natural increase, deriving from a disrupted age-sex structure, and net out-migration combine to account for a steady depopulation of Pskov Oblast. The introduction of industries providing additional male employment is recommended in the two principal cities—Pskov and Velikiye Luki—to correct the present predominance of women in industrial towns. Several measures (modernization of the countryside, promotion of truck-produce farming around the major urban centers) are suggested to keep more young people in rural areas and thus correct the lop-sided age structure there. Economic decision-making is viewed as a key factor in improving the demographic situation of a region.  相似文献

The distinctive aspects of settlement of the Far Northern regions of the Soviet Union are reviewed with particular reference to the Aldan district, a gold and mica mining area in southern Yakutia. The main source of population has been net in-migration, with two-thirds of the labor force consisting of persons who move to the area temporarily, usually for one to three years. The permanent segment of the population represents only about one-third of the total. Working ages predominate among the migrants, and there has been traditionally a predominance of males, especially in the early stages of area development. However the sex ratio tends to become balanced as an area matures and the economy becomes more diversified. Indigneous ethnic groups represent only 9 percent of the Aldan population, with Russians predominating among the migrants and representing 78 percent of the population.  相似文献

There is an increasing use of palynological data to infer prehistoric agricultural activity. The uncritical acceptance of the technique of pollen analysis by archaeologists and palynologists is questioned. Attention is focussed upon the nature of clearance activity and problems of its inference from pollen spectra; the spatial distribution of palaeoenvironmental sites; and the proximity of such sites to those of prehistoric activity. The resolution apparent in peat and lake sediment pollen profiles together with problems of dating and temporal inference, are examined. In response to a perceived lack of formalization in palynological research, some simple models of clearance activity are presented. The complexity involved in environmental reconstruction is emphasized by reference to the use of supplementary data to augment the orthodox pollen record.  相似文献

In the first attempt in the Soviet literature to investigate the activity spaces of urban residents, the author analyzes the movements of five groups of 10th-graders from schools in five parts of Moscow. The activity spaces display a general regularity of extending along radial subway lines from the outlying place of residence (and school) to the city center, demonstrating two basic characteristics: (1) the sectoral orientation of activity spaces; (2) the inclusion of the city center. In some cases where industrial districts intervene between place of residence and city center, the activity space becomes discontinuous. It is suggested that urban planners can effect any improvements in urban living conditions most efficiently through the medium of the activity spaces of urban residents.  相似文献

Opaline phytoliths are important microfossils used in archaeological and ecological research. Relatively little is known about the stability of phytoliths after burial. Under alkaline pH conditions they can dissolve, and mechanical disturbances can cause a loss of their more delicate appendages. Here we present an experimental study of phytolith stability (combination of solubility and abrasion). Modern and fossil phytoliths were extracted from wheat using new methods to minimize dissolution, and by burning in an oven. These assemblages were placed in a solution buffered to pH 10 and maintained under constant temperature and shaking conditions. The silicon concentrations in the solution were monitored once a week for 5 weeks. The phytolith morphologies in each assemblage were determined at the outset of the experiment and after 5 weeks. The results show that there are differences in stability between various assemblages. Modern inflorescence wheat phytolith assemblages are more unstable than those from leaves/stems. Burnt assemblages are less stable than unburnt assemblages, and a fossil phytolith assemblage about 3000 years old is more stable than the modern wheat assemblages. The results also show that individual phytolith morphotypes have different stabilities, and as a result of dissolution and abrasion, some morphotypes may resemble others. This study further shows that archaeological and/or paleo-environmental interpretation of phytolith assemblages may change with the assemblage’s state of preservation.  相似文献

It is widely recognized that folk beliefs flourished in early modern Finland which had formally been Christianized for centuries. These folk beliefs seem to propose, in the modern view, that people in the past believed in the existence of non-human beings, such as trolls and spirits, and considered a variety of material things from artefacts to landscape elements to have special properties, such as agency, consciousness, and personality. Folk beliefs, however, may have been misrepresented due to the assumption that they originate in religious-like thinking. This paper reconsiders the nature of folk beliefs, their relationship with religion, and their significance to archaeological interpretation both theoretically and through a case study. It is argued that folk beliefs in early modern northern Finland – and in other similar contexts – can be understood in terms of local perception and engagement with the material world. Folk beliefs, in this view, were embedded in the dynamics of everyday life, and they are, at least in the specific case discussed in this paper, indicative of two-way relatedness between people and various constituents of the material world. The archaeological implications of this view are discussed in the context of the 17th-century town of Tornio on the northern Gulf of Bothnia.  相似文献

On the basis of a number of socio-economic and physical requisites, the prospects of future development are examined for all 28 urban places of Smolensk Oblast as of early 1973. The requisites are the economic-geographic (transport) situation, availability of water resources, labor resources, economic base, industrial terrain and housing. The urban places are assigned point scales combining these factors and are assigned to three categories (with very favorable, favorable and unfavorable prospects of development). The allocation of places to particular development classes is then tested statistically by association with two additional variables: population size and functional characteristics, and the corrections introduced by the procedure are analyzed. The prospects for further development are found to be most favorable for the six largest towns—Smolensk, Roslavl', Vyaz'ma, Safonovo, Yartsevo and Gagarin. (The study was completed before the founding in 1973–74 of two new urban places that are associated with major power stations under construction and are thus endowed with growth prospects: Desnogorsk, on the site of the Smolensk nuclear power station, and Ozernyy, on the site of the Smolensk peat-fired power station.)  相似文献
