"The related topics of regional net migration and ethnic Russian population redistribution and change in the USSR are investigated for the intercensal period 1970-79 in comparison to 1959-70 by economic regions and subdivisions. The results reveal that the main migration and Russian shifts continued to be from internal to peripheral regions. However, compared with the 1959-70 period, regional rates for 1970-79 were more equalized, and a south-to-north shift seemed to be occurring in both cases." The author notes that "aggregate measures...suggest that the traditional eastward movement of Russians is slowing. Correlation analysis indicates that migration and ethnic Russian change patterns are associated with selected indices of modernization. The south-to-north shift, in particular, has been fairly strong in relation to changes in capital investment. Prospects of a northward migration of Turkic Moslems from Central Asia are also discussed." 相似文献

Using the preliminary results of the 1979 census, the authors analyze trends in the distribution of the population of the USSR. Topics considered include the role of natural increase in the redistribution of the population, the relationship between economic development and the rate of population growth in Siberia, the effects of increasing rural-urban migration, and changes in the number and distribution of large cities. 相似文献

"Data from the preliminary results of the 1989 census and Naseleniye SSSR 1987 permit analyses of age-sex structures of the Soviet population and distributions by civil divisions of natural growth rates, total population growth, urban growth, rural growth, percent urbanization, and growths of cities. The paper complements the treatment of census results by macroregions appearing in the November 1989 issue of Soviet Geography...by summarizing trends emerging at a finer scale of analysis and providing recent background information on demographic components of population change." 相似文献

"This article examines union republic migration trends in the USSR between 1979 and 1987 and prospects for indigenous out-migration from rural areas in Central Asia. The study is based on migration data derived by the residual technique and migration data from the 1985 microcensus. Results indicate that a south-to-north and probably Russian-dominated migration trend emerged in the 1980s, one which marks an almost complete reversal from earlier periods, especially 1959-70. Although Central Asia continues to have low levels of indigenous out-migration, labor surpluses and relatively waning capital investment in Central Asia may change this situation." 相似文献

"The primary purpose of this paper is to assess very broadly the regional growth and redistribution of the total, urban and rural populations of the USSR, as well as aggregate, regional and city size patterns of urbanization for the 1979-84 period. In order to investigate the continuity or reversal of trends, comparisons with preceding intercensal periods will also be undertaken, particularly with the 1970-79 period." It is found that "regional rates of population change between 1979 and 1984 were generally lower than those of 1970-79, primarily due to a general decline in natural increase rates. In addition, regional variations in rates of population change for the 1979-84 period were similar to those of the 1970-79 period.... The USSR has apparently reversed its long-term trend of deconcentration in the sense that the population as a whole is becoming more concentrated again, but this time in a new area of concentration, Central Asia, which is now the most populous economic region." 相似文献

"This article investigates economic region net migration patterns in the USSR during the 1979-89 intercensal period. Net in-migration and net migration rate increases (compared to 1970-79) occurred in both the western and eastern portions of the Northern USSR region, while net out-migration and rate declines occurred throughout the Southern USSR. Net in-migration again occurred to Siberia, especially Tyumen' Oblast, and there was a reduced rate of net out-migration from the Nonchernozem Zone and Central Chernozem Region of European RSFSR." 相似文献

"Patterns of population distribution revealed from 1989 census data are used to assess how future population movements could be affected by current political, social, and economic changes. Much migration in the USSR has reflected central planning decisions as much as the spontaneous decisions of individuals. To the extent that the influence of the command economy diminishes and a market economy emerges, major new directions of migration flows can be expected. The return of ethnic 'expatriates' to home republics can be expected to increase, as can economic migration to areas with favorably perceived economic prospects, and migration to Central and Western Europe." 相似文献

"Interregional migration results in a regional redistribution of labor, essential under the current mismatch between the locations of labor and of natural resources and industrial capacity in the USSR. This study focuses on economic and geographical determinants of destination choice of migrants from 1968 through 1985. Particular emphasis is placed upon the relative effects of economic variables and quality of life factors and on the effect of gravity variables (i.e., distance and population size). The statistically significant results for the economic and gravity variables indicate the appropriateness of using Western theories to analyze migration in the Soviet context." 相似文献

"An overview of the dynamics of Soviet cities of over 100,000 population for the period 1979-1989 is presented, based largely on maps and tables depicting five key 'subsets' or city groupings: (a) cities increasing by over 100,000 inhabitants; (b) the fastest growing cities in percentage terms; (c) their comparison with fastest growing cities, 1959-1979; (d) the slowest growing cities in percentage terms; and (e) their comparison with slowest growing cities, 1959-1979. The paper, by focusing on these parameters and utilizing extensively graphic and cartographic methods of data presentation, provides...insights into city growth trends...." 相似文献

The authors comment on an article by Bond and Lydolph (see 46: Title 1088) concerning population growth in the USSR during the inter-censal period 1970-1979. In the present article, the authors use a more detailed analysis of the preliminary results of the 1979 census in order to illustrate other major developments 相似文献

Time-domain electromagnetic (TDEM) migration is based on downward extrapolation of the observed field in reverse time. In fact, the migrated EM field is the solution of the boundary-value problem for the adjoint Maxwell's equations. The important question is how this imaging technique can be related to the solution of the geoelectrical inverse problem. In this paper we introduce a new formulation of the inverse problem, based on the minimization of the residual-field energy flow through the surface or profile of observations. We demonstrate that TDEM migration can be interpreted as the first step in the solution of this specially formulated TDEM inverse problem. However, in many practical situations this first step produces a very efficient approximation to the geoelectrical model, which makes electromagnetic migration so attractive for practical applications. We demonstrate the effectiveness of this approach in inverting synthetic and practical TDEM data. 相似文献

清初,伊犁地区人口稀少、边防空虚,清政府为了充实伊犁地区的防务力量,采取了人口迁移的方式,移民固边。移民的群体主要来自两个地方,一是南疆地区的维吾尔族民众,迁入伊犁河谷从事农业生产,是迁入的高峰时期乾隆年间到道光年间,迁入人口的总数在一万人以上。光绪年间,伊犁地区部分维吾尔移民被迫迁入俄罗斯;二是来自东北盛京地区的锡伯族,迁移人口为四千零三十人,迁入的主要目的是永久性的驻守边防,减少政府的军费开支。经过移民的建设,到新疆建省时,伊犁地区已经成为新疆的政治、军事中心。 相似文献

改革开放以来中国国内人口迁移及其研究 总被引:25,自引:7,他引:25
从人口迁移进程的变化、人口迁移的主要原因与迁移选择和迁移方式、迁移人口对城市社会经济活动的参与及影响等方面,综述中国改革开放以来的人口迁移进程及研究成果。大量的实证研究,使人们对中国国内人口迁移有了日益清晰的认识,但多数仍停留在国外人口迁移理论的框架之内。在人口迁移与加快户籍制度改革、与城市居民就业和产业结构调整的关系,及迁移人口对区域社会经济发展差异分析比较的影响等方面还需进行深入研究。 相似文献

Due to rapid socio-economic development and urban-rural integration, the rural population is increasingly moving away from the primary industry, leading to a noticeable transformation of rural farmland use. This paper analyzed the changes in farmland use and the mechanisms in 213 villages of Longxi county, China in 2020, using multiple linear regression models, based on the aforementioned situation. Analysis revealed main findings:(1) Male and young and middle-aged emigration levels are concentr... 相似文献
