The delta of the Volga River on the Caspian Sea is a highly dynamic form, whose growth has been affected by a combination of physical and human factors. Rapid delta growth in recent years has resulted in a deterioration of both physical and economic conditions (navigation problems, inadequate moisture supply, overgrowing of shallows with vegetation, loss of spawning grounds). Regression analysis yields a number of relationships between the inflow of water and suspended sediments, on the one hand, and delta growth, on the other hand, with a distinction between periods of a lowering of the Caspian Sea level and relative stability. The regression equations are used to project the likely future evolution of the delta. The only combination of conditions that is likely to limit further delta growth by the year 2000 is the stability of the Caspian Sea level and a period of average moisture supply. In all other cases, the delta is likely to continue its undesirable advance.  相似文献

Recent discoveries in different parts of the Near East have led the authors to reconsider the early history of metal driving bits. These now seem to go back into the third millennium BC, which is much earlier that the evidence previously indicated. The paper also includes a brief discussion of the links – if these existed at all – with early bridle bits made of organic materials from the southern Urals–Volga area.  相似文献

The water requirements of the Moscow region, now estimated at 6 cubic kilometers a year, are expected to increase by a factor of 2.5 to 3 over the long term in connection with higher water use rates for households and municipal uses, industrial expansion and the proposed development of perennial pasture lands for livestock. Over the short term, Moscow's additional needs are to be met from two major sources: (a) additional transfer of water from the Ivan'kovo Reservoir on the Volga River north of Moscow; (b) development of a water-transfer system from the Ugra River (a left tributary of the Oka River), southwest of Moscow. Over the long term, the region's water resources may have to be replenished from Lake Ladoga or from the Volga River's Rybinsk Reservoir, which may by then also be receiving additional water from northern streams.  相似文献

The reports of Arab geographers and numismatic data are combined in a review of the literature on two major transit trade routes in Eastern Europe: the Baltic-Caspian trade route and the route “from the Varangians [Scandinavians] to the Greeks [Byzantium].” Hoards of Arab silver coins, known as dirhems, along major water routes clearly point to the direction of the Baltic-Caspian route along the Volga, and date the earliest use of the route from the late 8th century. Trade along the route involved mainly the Volga Bulgars, Ugro-Finnic and Letto-Lithuanian tribes, but not the Slavs, as had earlier been supposed. The existence of the route from the Baltic to the Black Sea along the Dnieper River (“from the Varangians to the Greeks”) was reported by two 11th-century historians—an unidentified Russian chronicler and Adam of Bremen. The author rebuts recent suggestions that the Dnieper route was not as significant as commonly assumed.  相似文献

A noted investigator of Russia's ethnic and geopolitical affairs presents case studies of six regions (in aggregate home to ca. 5.8 million Muslims, or over one-third of Russia's total) within the Volga and North Caucasus districts in an effort to demonstrate the importance of the regional context in which Russia's Muslims reside. Drawing upon field interviews (through March 2006) and information from local media, the author shows how the milieu in which Islam is practiced diverges markedly across regional boundaries. The diversities are traced to location, history, ethnocultural affiliation, number of adherents, educational resources, and relations between Islamic leaders and government officials. Also analyzed is the role of the two major competing spiritual centers of Islam in Russia, and the sense of regional self-identity.

土尔扈特蒙古西迁至伏尔加河流域后,其经济状况可以概括为:传统游牧经济由盛而衰;以互通有无为基础的对俄贸易往来不断;为俄国军事战役出兵助战获得战利品和报酬成为特殊的收入来源;突袭其他民族和控制贸易路线是增加财富的渠道之一;捕鱼成为相当一部分生活贫困的土尔扈特人赖以维持生计的重要方式。作者认为经济状况恶化是促使土尔扈特蒙古东归的原因之一。  相似文献

According to the general modern view the steppes of the northern Black Sea region, from the Danube to the Ural valleys, in the period from the third century BC to the mid‐third century AD, were inhabited by Sarmatian tribes using a burial mound rite. Several consecutive waves of Sarmatian peoples came to this territory from the East, conquering the local population. This view is based on the paradigmatic explanatory model, which has its roots in the history of the Russian Empire. However, the archaeological culture of the Volga–Don and Ural steppes, known as the ‘Sarmatian Motherland’, is apparently not related to the Sarmatians of the written sources. In addition, the culture of the northern Black Sea region features various kinds of archaeological monuments (settlements, votive depositions, kurgans, flat necropolises), which are characteristic of different cultural‐economic types. This demonstrates the complexity and diversity of the culture in the region, which could be influenced by many factors: the presence of Greek settlers on the northern shore of the Black Sea, the expansion of the Roman Empire, the pressure of nomadic tribes from the East, the advance of the CelticThracian peoples from the West, changing environmental conditions, etc.  相似文献

The article describes the traditional spring festival of Aka?ka celebrated by the Southern Udmurts. The content and form of the festival indicate that some elements were borrowed from the Turkic world. While some borrowed elements have their counterparts in the ritual practices of the Turkic-speaking peoples of the Middle Volga region and the Urals, the sources of other borrowed elements can be found in the Turko-Mongolian environment of southern Siberia and the Altai.  相似文献

The Volga region, which owes its economic development in considerable measure to its favorable transport situation, is expected to continue as a major transit region, as fuels and energy [oil, gas, electric power] are transmitted from newly developed Siberian areas to the manufacturing centers of European Russia. Because of the importance of the east-west routes, railroads will continue to play a key role in the regional transport picture, but pipelines and waterways are planned to become more important.  相似文献

On the basis of early chronicles, statutes, and maps, as well as toponyms, the author retraces the river routes and portages used by Novgorodian and Rostov-Suzdalian tribute collectors, traders, and soldiers travelling from the upper reaches of the Volga to the White Sea slope in the 12th-14th centuries. He also indirectly assesses the negative and positive impact of these waterways on the physical environment on the basis of artifacts and logic. (The translation was prepared by James R. Gibson of York University, Toronto).  相似文献

The author tries to show that the level of the Caspian Sea could be stabilized at relatively low cost at its present low level without further damage to the coastal economy. He denies the need for costly projects designed to increase the inflow into the Caspian or to separate the shallow northern section from the main body of the sea. He maintains that water gained by diverting the northern streams into the Volga basin should be used to irrigate the arid Southeast rather than to replenish the water supply of the Caspian Sea.  相似文献

The author of an economic geography of the Komi ASSR (1959) attempts to show that the present plan for the diversion of the Vychegda and Pechora rivers to the Volga basin would have an adverse effect on the economy of the Komi ASSR, particularly by flooding the limited amount of agricultural land available in the northern republic. Fisheries and shipping on the Pechora River would also suffer, in the opinion of the author. He proposes certain changes in the engineering aspects of the project to safeguard the northern economy. The changes would admittedly double the cost of the project.  相似文献

This article offers a historical retrospective of the interactions between Russia and the Islamic world in all their diversity, beginning from the first trade contacts of Medieval Rus with the Arabs and Persians of the Abbasid era, as well as with the Turkic-speaking residents of Volga Bulgaria. The author concludes that except for the initial sporadic period, the connections between Russian and Muslim worlds have been stable and close throughout all the following periods. Moreover, with time, these two civilizational communities turned into communicating vessels because of the growing number of Muslims within the Russian State and in Russian society. Special attention is paid to Russian-Turkish relations across several centuries. A complete comprehension of the relations between Russia and the Islamic world through an example of the historical retrospective of Russian interactions with the Ottoman Empire and the Republic of Turkey helps to provide a full appreciation of the importance of joint efforts to secure a bridge connecting East and West and the oriental civilizations with Russia.  相似文献

Using the example of the Soviet Union's principal oil-producing region between the Middle Volga and the Urals, the authors identify systems of urban settlement and classify urban places in terms of their situation within systems of settlement. The situation of a place within a system is used as a criterion for determining whether future industrial growth of that place should be stimulated or restricted. A related article by one of the authors, F. M. Listengurt, appeared in Soviet Geography, October 1965.  相似文献

The period between the 1959 and 1970 Soviet censuses represents one of stability insofar as demographic processes have not been disturbed by external factors, in contrast to the upheavals during and after the 1939–1945 war. Nevertheless, basic population structures, in particular the varying levels of urbanization, have been modified by internal migration of people from the countryside to the industrial towns. Consequently in European Russia rural areas, while increasing their population in absolute terms, have suffered severe losses in favour of the expanding industrial zones, especially the Ukraine and the lower Volga region. Methods of calculating this change must involve careful scrutiny of the data and also an appreciation of settlement patterns as well as purely demographic features.  相似文献

A report on a 1974 conference on interbasin transfers from Siberia to Central Asia compares the alternative stream-diversion projects west and east of the Urals and finds that north-south interbasin transfers in the European part of the country have a better chance for early implementation than the diversion from Siberia to Central Asia. The author urges consideration of a unified water-management system within the European part of the Soviet Union that would make it possible to dispatch streamflow from one basin to another much as electric power is transmitted through interconnections between power grids. Such an interconnected water-management system would be based on the premise that runoff volumes tend to be nonconcurrent in the various drainage basins of the Russian plain so that surplus runoff from “donor rivers” (Pechora, Northern Dvina, Onega and the lakes Onega and Ladoga) might be channeled southward to “consumer rivers” (Volga, Don, Dnieper and Ural).  相似文献
