A review of potential local fresh-water sources in the deserts for the use of livestock herds, herders' settlements, and extractive and other industrial enterprises. One of the most promising approaches is held to be the use of takyrs [clay pans] as catchment areas for ephemeral runoff of precipitation, which is then directed into natural aquifers or artificial underground storage cisterns. Another potential source of water is large perched ground-water lenses that could be tapped by paired wells to prevent the intrusion of salt water from below. Artesian waters in the desert which are far from areas of recharge are found to be largely saline.  相似文献

A water-management regionalization and determination of marginal cost estimates of water resources over the next three decades (to about 2000) outlines a set of priorities for the construction of dams and interbasin diversion projects. The predicted water requirements are based on the assumption that irrigation needs will increase at a moderate rate (30 million hectares by the end of the forecast period). The resulting marginal cost estimates are expected to affect long-term plans for the location of water-intensive activities (irrigation, water transport, thermal power generation, chemicals, pulp and paper) for which water costs may represent 40 to 50 percent of the total cost difference between alternate locations.  相似文献

试析苏联犹太移民问题的形成及影响   总被引:3,自引:0,他引:3  
白玉广  宋正 《史学月刊》2002,98(4):90-97
苏联犹太移民问题是苏联历史和政治、经济发展的产物。由于受多种因素的影响,苏联对犹太移民的意愿采取限制性的政策。由此产生了苏联政治生活中移民申请被拒绝这一特殊的政治群体。他们以移居苏联国外为其主要的政治目标。苏联犹太人的移民意愿及移民申请被拒绝的活动引起西方社会尤其是美国的关注,并在一段时期内成为影响美苏经济贸易关系的一项重要因素。戈尔巴乔夫实行的改革开放政策在一定程度上缓解了这一问题,此后苏联的解体使这一问题的性质和重要性均有所转变。  相似文献

Surfaced roads, including gravel roads, total 510,000 km, or 37.5 percent of the Soviet Union's motor-road net of 1.4 million kilometers, the rest consisting of dirt roads. Only about 260,000 km, or less than one-fifth, consists of blacktop or cement or asphalt concrete highways. The lack of roads tends to cause considerable losses to the Soviet economy, particularly in agriculture. An accelerated road-building program is therefore under way, with the current five-year plan (1971–75) calling for the construction or reconstruction of 110,000 km of improved surfaced roads (blacktop and cement or asphalt-concrete) compared with 75,000 km added in the preceding five-year period (1966–70). The densest road nets in the USSR are found in the Baltic republics, in Transcaucasia, Moldavia, the Ukraine and Belorussia. The lowest road-density indices apply to the Russian republic and to Kazakhstan.  相似文献

美国特殊利益集团对全球霸权主义的追求、根深蒂固的反共主义,以及为维护世界资本主义的一统天下,决定了美国对苏联意识形态进攻的必然性。在苏联存在的几十年间,美国从未放弃消灭或西化苏联的图谋。在苏联基本坚持马克思主义的指导和社会主义道路的情况下,这种图谋难以实现。但是,当苏联把马克思主义教条化和僵化,并在西方和美国意识形态进攻面前逐步西化,就潜伏了巨大危险。一旦苏联领导彻底抛弃马克思主义意识形态,而以美国等西方国家宣扬的所谓"全人类价值观"作为指导时,苏联的解体和西化也就变得不可避免。  相似文献

A survey of the recent history of development, shifts in locational patterns and changes in organizational structure of the craft industries of Gor'kiy Oblast, one of the principal craft-industry areas of the Soviet Union. The authors map changes in the distribution of crafts and analyze economic-geographic factors in locational changes. Recommendations are made to preserve some of the crafts within the pattern of the Soviet economic system.  相似文献

A detailed survey of the location and scope of radionuclide contamination in the former USSR examines the character and spatial patterns of such contamination by source—e.g., commercial and military reactor operation (including reactors on submarines and icebreakers); uranium mining and enrichment; plutonium production; nuclear waste storage and disposal; and “peaceful” nuclear explosions and nuclear weapons tests. Attention also is focused on updating the situation at sites known to have sustained some of the most severe radionuclide contamination—e.g., Chornobyl' (Chernobyl') and adjacent areas; Mayak, Tomsk-7, and Krasnoyarsk-26; Novaya Zemlya; the Barents and Kara Seas; Lake Ladoga; and Semipalatinsk in Kazakhstan. 5 figures, 8 tables, 60 references.  相似文献

A review of the present state of Soviet medical geography based on an analysis of papers presented at the Second National Medical Geography Conference held in Leningrad in November, 1965. The authors, representing four departments of the Geography Faculty of Moscow University, stress geophysical and geochemical causative factors of human disease and the contributions being made by medical landscape science in relating environmental prerequisites to particular diseases.  相似文献

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

The economic development of the eastern regions, including Siberia and the Far East, Kazakhstan and Central Asia, has been hampered by manpower shortages (except in Central Asia) and the high cost of construction. However the generally more favorable conditions for resource development are viewed as a sound basis for further industrialization of the Eastern regions, focusing on fossil fuels and electric power and on industries consuming large amounts of fuel and power (nonferrous and ferrous metals, some chemicals, and forest products). In view of the need for integrated regional development, primary resource-based industries should be supplemented by some manufacturing, particularly heavy machinery industries and pulp and paper. Savings in construction could be achieved by investing in territorial-production complexes with interrelated industries and common engineering and transport systems.  相似文献

Food Deserts: Towards the Development of a Classification   总被引:1,自引:0,他引:1  
Many people in developed countries fail to consume a healthy diet. This phenomenon has been linked to the contested existence of ‘food deserts’ in the UK, and the occurrence of ‘food insecurity’ in the USA and elsewhere. ‘Food deserts’ remain contested theoretical territory at least partly because no firm definition has been proposed. This paper argues that the barriers to consumption of a healthy diet may be classified according to whether such barriers are financial, physical, or derive from the mental attitude and knowledge of the consumer. The perception of ‘unsupportive food environments’ by some consumers is contrasted with the geographical existence of multiple sources of fresh fruit and vegetables in certain locations. Using a total of 234 semi—structured interviews in various UK locations, qualitative evidence is gathered for the existence of at least ten different types of ‘food desert’. The paper then goes on to show how such a three fold classification may be developed, using a modified ternary diagram, to assess the most appropriate initiatives to tackle ‘food deserts’ and to monitor progress in alleviating their effects.  相似文献

The predominance of individual migration and a lack of coordination among government agencies result in a situation in which migration in the USSR often works at counter-purposes, with people moving away from areas suffering from a labor shortage and into areas with a labor surplus. A system of economic measures is advocated to optimize Soviet migration patterns. Since differences in living conditions are the basic motive between migration, an effort should be made to establish relationships between region al living standards that would attract migrants to regions with a labor shortage and induce them to settle permanently, instead of taking temporary advantage of high wage rates.  相似文献
