The author views British Columbia as a typical newly developed industrial region of the advanced capitalist countries, in which stress is placed on the development of raw materials and semi-finished goods for the export market. The region's transportation, electric power, metallurgical and forest industries are reviewed in detail. High labor productivity and advanced technology are found to be typical of the development of British Columbia, whose experience is found applicable to parts of Siberia.  相似文献

A review of broad research problems leading to ultimate transformation of the Central Asian environment for the purpose of expanding irrigated agriculture and desert grazing. The problems are: land resources and reclamation needs for irrigation purposes; the water and salt regime of irrigated fields, regional types and methods of control; the water and salt budget of irrigated areas and means of determining and regulating it; the hydrologic cycle of Central Asia and ways of transforming it for irrigation purposes; and the use of forage and water resources for expanding the desert grazing economy.  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 In Magadan Oblast, the present scattered pattern of small populated places is to be superseded by greater concentration of urban population in a set of subregional service centers.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

The paper discusses, mainly from a programmatic point of view, the need for research into the relationships between climate and vegetation. Four lines of research are proposed: (1) the correlation between the distribution of vegetation and climate indices; (2) relationships between the distribution of vegetation and seasonal types of climate; (3) seasonal and annual changes in plant communities related to corresponding changes in the surface layer of the atmosphere and the soil and subsoil; (4) the exchange of matter and energy within an ecological system.  相似文献

The security dimension of regionalism and regional structures in Central Asia and Azerbaijan has been limited by Russia's influence as a regional hegemon, aswell as by various other constraints specific to the region and the local states. Moreover, as a peripheral zone in the world system, Central Eurasia has not shown much evidence of regionalization as a process. But in response to the proximity of hegemonic power the smaller states have tried to adopt bandwagoning and balancing strategies in regional formats. Although their fixation on 'regime security' has encouraged them to accommodate Russia through CIS structures, this is changing as new bilateral security relationships develop with the United States. The Russian-sponsored Collective Security Treaty Organization is unable to address the most serious challenges for regional security management in Central Asia. Yet the local states have been unable on their own to establish a regional security consensus and to institutionalize cooperation on that basis. The diffuse GUUAM grouping (Georgia, Ukraine, Uzbekistan, Azerbaijan and Moldova) has not offered a basis for selfsustaining regional security cooperation. The Shanghai Cooperation Organization has created a venue to engage China in the security dialogue on Central Asia, particularly over counterterrorism, but has otherwise failed to tackle security challenges among and within the Central Asian states. Overall, the current focus of these states and their sponsors on bilateral relations to provide security assistance continues to displace security-related regionalism.  相似文献

A pair of Hong Kong and U.S. specialists on China examines the dynamic international environment China's new leadership now faces, focusing on East Asia. They first examine the complex balance the leadership seeks to strike between: (1) China's projection of increasing economic, military, and political power internationally; (2) the primary domestic goals of economic growth and stability; and (3) rising public awareness, demand for information access, and (in some quarters) nationalism among the Chinese people. The authors then proceed, in successive sections of the paper, to assess in greater detail China's international and regional security environment, Sino-American relations, China's relations with its East Asian neighbors, and the complex interconnections between the country's domestic and foreign policy. They conclude that Sino-American relations will continue to be pivotal to Beijing's foreign relations in general and its relations with countries in the East Asian region more specifically.  相似文献

Over the last decade there has been a proliferation of discourses on Asia-Pacific regional security. An analysis of the predominant discourses of regional security suggests that a new orthodoxy is emerging. This orthodoxy is characterised by attempts to create a 'fusion' between the dominant security and strategic concepts of neo-realism, neoliberalism and an 'Asian way' of security. Yet the way in which the difference of an Asian way of security is constructed in relation to the 'West' remains essentialist. Despite its regional focus, the new orthodoxy does not disturb the sanctity of the principle of sovereign statehood, nor does it unsettle the status quo of political communities within the nationstate. As a result, significant differences between and below the level of states in the region are not recognised.  相似文献

The author finds conventional physical-geographic regionalization inadequate for economic-geographic purposes, and proposes instead a “natural regionalization” or regionalization of natural resources. Such a regionalization would reflect the economic assessment of the natural environment of a given area and would be more appropriate in economic-geographic research. The principles underlying natural-resource regionalization are illustrated with a regional scheme for the Sudan, an area to which the author has devoted special study.  相似文献

This paper examines the distribution of water and the location of physical and political boundaries in Central Asia, identifies indicators of the susceptibility of its various regions to resource and water-related conflict, and then applies those indicators to discover the potential for future water-based regional conflict. The dimensions of the problem are addressed not only in terms of the physical availability of water (or lack of same), but also water quality and regional social unrest as a consequence of migration from regions of environmental deterioration. 5 figures, 4 tables, 45 references.  相似文献

This paper presents regional sequences of production, consumption and social relations in southern Spain from the beginning of the Neolithic to the Early Bronze Age (c. 5600–1550 BC). The regions studied are southeast Spain, Valencia, the southern Meseta and central/western Andalucía. The details presented for each region and period vary in quality but show how much our knowledge of the archaeological record of southern Spain has changed during the last four decades. Among the surprises are the rapidity of agricultural adoption, the emergence of regional centres of aggregated population in enclosed/fortified settlements of up to 400 hectares in the fourth and third millennia BC, the use of copper objects as instruments of production, rather than as items with a purely symbolic or ‘prestige’ value, large-scale copper production in western Andalucía in the third millennium BC (as opposed to the usual domestic production model), and the inference of societies based on relations of class.  相似文献

A review of the use of energy and mass budget studies of natural landscapes discusses some limitations of the approach, related partly to a lack of detailed knowledge about the structure of landscape and the inadequacy of the balance technique for describing indirect linkages within the landscape and the impact of outside regulatory influences. The various balance equations for describing the mass and energy exchange in landscape are described and systematized. The use of heat-balance and plant-mass balance relationships for a classification of natural areal complexes is illustrated with reference to the north-facing and south-facing sides of a gully, the gully bottom and the surrounding watershed area in a meadow-steppe landscape of the Central Chenozem Region. Other possible applications of the balance technique in mass and energy research are suggested.
