The economics of Central Asian transportation are such that railroads are more economical than waterways if they run parallel, but water transport is considerably more economical than motor transport in the absence of railroads. This explains why shipping was never significant along the Syrdarya, one of the two major streams of Central Asia, which has been paralleled by a railroad (from Orenburg to Tashkent) since 1906. The situation was different in the case of the Amudarya, which was paralleled by a railroad in its lower reaches only since 1955. The significance of shipping on the Aral Sea is declining rapidly as more water is being withdrawn from its tributary streams for irrigation and the sea level is dropping. The author sees a future for water transportation on a southern east-west route made up by the upper reaches of the Amudarya and the Karakum Canal. However, such a route would require considerably additional capital investment on the canal to make it accessible to larger barges.  相似文献

The impact of industrialization and urbanization on the natural environment of Europe is analyzed and compared on the basis of regional reports submitted by 15 nations to the 1968 Unesco conference on the resources of the biosphere. For purposes of analysis, the nations of Europe have been grouped into capitalist countries, the socialist countries of Central and Eastern Europe, and the USSR. All of them are found to be affected by the same problems of increasing volumes of industrial and municipal wastes, a drift of population to the cities and growing air and water pollution. But the socialist nations are said to be distinguished from the capitalist countries in implementing systematic government control over all forms of pollution, providing recreational zones for the population at large, expanding a network of natural areas with conservation and amelioration of flora and fauna, and carrying out a broad program of transformation of nature designed to make optimal use of resources and to conserve and ameliorate the environment.  相似文献

A review article of recent Soviet futurological articles in the geographical literature, suggesting the increased activity of Soviet geographers in the prognostication of the environmental effects of human activity. Several of the papers under review appeared in Soviet Geography: Review and Translation.  相似文献

A regionalization of Moscow Oblast is derived from a physiologic-climatic evaluation for purposes of settlement and recreation. The evaluation is based on the frequency of occurrence of particular classes of weather through the year. The most common classes in Moscow Oblast are the 1C class (light negative heat balance), which is determined by global macrofactors and produces an undifferentiated background in the oblast, and the N class (comfortable condition of heat equilibrium) and 2C class (moderately negative heat balance), which reflect more localized factors and can be used for a differentiated evaluation of physiologic-climatic conditions. Eleven physiologic-climatic regions are delimited on the basis of the difference between the number of days with comfortable conditions (N class) and the number of moderately cold days (2C class). Optimal conditions for settlement and recreation are found south and southeast of Moscow; the most unfavorable in the low-lying swampy Dubna area, where the Moscow-Volga canal meets the Volga River.  相似文献

Landscape science, as a discipline concerned with the integrated investigation of natural areal complexes of different ranks, has been gaining an increasing range of practical applications in connection with optimal design of cultural landscapes. The paper focuses on the use of applied landscape maps in investigations designed to make optimal use of the ecological potential of natural landscapes and their morphological subdivisions. Five types of maps are distinguished, corresponding to successive stages in the investigation. An inventory map presents a picture of the present state of the natural complexes, with emphasis on those features that are most relevant to the stated applied purpose (recreational use, agricultural use, engineering applications, etc.). An evaluative map classifies the natural complexes in terms of their suitability for the stated purpose. A predictive map focuses on the likely future behavior of these complexes, and a recommendatory map lists measures required to enhance the potential of natural areas for particular purposes. The ultimate result is a synthesized map of the entire proposed cultural landscape.  相似文献

An important technique of economic-geographic prediction is the comparative analysis of alternative combinations of productive forces that are likely to modify the existing system of the geographical division of labor and the system of economic regions. A suggested sequence of steps is designed to locate future productive capacity to a maximum extent in already developed regions with minimum inputs into new territorial development. Only industries whose growth cannot be insured in developed regions should be located in new pioneering regions. The predictive process is illustrated with particular reference to the economic development of the USSR up to the year 2000 and beyond. The principle of uniform spatial development, once a keystone of Soviet economic planning, is found to be economically unsound. Rapid returns on investment can be obtained by more intensive use of existing developed territories.  相似文献

Spaee-time shifts are analyzed for a particular type of suburban recreational, development—the cottage, settlements and garden cooperatives around Moscow. Measurement of the appearance, stabilization and decline of this recreational function along six major rail lines radiating from Moscow shows a centrifugal shift fostefed by the development of high-speed transportation and the conversion of older recreational areas close to the city to residential and industrial uses. A characteristic feature of the expansion of the recreational zone Over time has been a leaping movement in which the centers of recreational development, after having taken shape for one or two decades, will suddenly leap outward to a more distant zone. Furthermore, suburban cities are beginning to generate their own demand for recreational space and are becoming nuclei of their own recreational zones.  相似文献

The author argues against the widespread view (stated in several articles in Soviet Geography) that labor-intensive industries should be kept out of Siberia because of the shortage of labor resources in that region. Taking the specific example of labor-intensive machinery industry such as instrument-making, as opposed to steel-intensive industry, he points out that labor-intensive plants, by virtue of their smaller size, usually have smaller labor requirements than large heavy-machinery manufacturing plants. Moreover, he argues, location must not be based on total population or total labor resources of a region, but on the availability of so-called free (nonemployed) labor resources, which consist largely of women and of young people just entering upon a career. This category of labor resources happens to be greater in the eastern regions than in the western regions of the Soviet Union. In fact, one reason for the net out-migration from Siberia, according to the author, is that second and third members of households find it difficult to obtain jobs in a regional economy that is largely oriented toward male employment (in extractive industry, timber felling, etc.). The introduction of labor-intensive industries into existing Siberian industrial complexes would thus help provide employment to other household members and eliminate one reason for out-migration.  相似文献

Large urban agglomerations, which have been viewed as undesirable by some authors, are described as legitimate and efficient forms of economic organization and settlement in a modern industrial society. A number of processes in the Soviet economy tend to foster the development of agglomerations; however, the trend toward agglomerations in the USSR is still at a very early stage compared, say, with the United States. If agglomerations are defined on the basis of a central city of 250,000 or more, the USSR had 75 agglomerations in 1970 compared with 240 standard metropolitan statistical areas in the United States. In contrast to the United States, where suburban development has outstripped central-city growth, three-fourths of the population of Soviet agglomerations is concentrated in central cities. In the author's view, control of the evolution of agglomerations should not be designed merely to curb big-city growth, but to foster the development of these urban clusters within the limitations of environmental constraints.  相似文献
