The original author of the great Siberian diversion scheme defends his views at a 1965 conference on multipurpose use of the water resources of the Ob' basin. Noting the development of West Siberia's oil and gas resources, which was just beginning to get under way, Davydov says it would be a mistake to base the local use of water resources solely on the interests of the oil and gas industry. He also rejects objections of the fishery industry to the construction of hydroelectric stations, and contends that the diversion of Siberian waters to the heavily populated and developed southern regions of the USSR will be essential to insure adequate water supply by the year 2000.  相似文献

Abstract

The authors review expected water requirements within the Volga-Caspian basin for industry, agriculture, fisheries and municipal uses and plans for the diversion of the streams of northern European Russia to the south to support the level of the Caspian Sea. They suggest that the diversion of part of the flow of the northern streams and isolation of the natural evaporation basin of the Kara-Bogaz-Gol will be sufficient to maintain the Caspian Sea level at ?28 meters. Previous articles on the Caspian problem appeared in Soviet Geography, September 1961, January 1962, and June 1963.  相似文献

A geomorphic field survey conducted in the late 1960's by the Institute of Geography (Moscow) suggests the existence of only one geomorphic level (Level III) that can be traced all the way through the Turgay trough from the Irtysh River drainage basin to the Aral Sea depression. However, contrary to general assumption, geomorphic analysis does not confirm the view that the Turgay trough served for a throughflow of water between the two drainage basins during the Pleistocene. An analysis of the geomorphic levels in the trough suggests that water in the northern segment of the trough drained toward the north and in the southern segment toward the south, with a middle segment occupied by a system of lakes, still evident to this day. However, the absence of a throughflow in the past does not rule out the use of the trough for the proposed southward diversion of Siberian water. It is suggested that the level of water on the Siberian slope be raised to the elevation of the divide (about 125 meters above sea level) so that the water could then follow the natural slope of the Level III surface toward the south.  相似文献

The Transformation of the Caspian Sea   总被引:1,自引:0,他引:1  
The author reviews the problem of the level fluctuations of the Caspian Sea, particularly the steady drop since 1929. The drop in level is affecting many key sectors of the regional economy. Among several remedial schemes is a plan for diverting the rivers of northern European Russia to the Caspian, and a project for a localized regulation of the level of the Caspian Sea.  相似文献

A regional review of existing and planned irrigation projects in the desert zone of the Soviet Union envisages the use of water from the Siberian streams in the northern section of the desert zone. For increased water supplies in the south, the author looks to other potential sources such as artificial increases of precipitation in the mountains of Central Asia, elimination of wild growths of water-loving plants, and technological advances that will make possible the economical desalting of water from salt lakes and of mineralized subsurface waters.  相似文献

The construction of the Ivdel'—Ob' railroad has opened up the rich timber resources of the Sos'va section of the Ob' River basin. Fifteen logging centers are in operation along the rail line, shipping 3.5 million cubic meters of timber, mainly as roundwood. Selective logging practices used at the present time tend to deplete timber reserves more rapidly than planned. To preserve the Sos'va region as a long-term supplier of timber for the industrial regions of the USSR, sound forest management is recommended, including multipurpose utilization of felled timber and reforestation. The forest products industry will be more economical if about 70 percent of the felled timber is converted into marketable wood products in major mill complexes planned for the region, leaving 30 percent for shipment as roundwood (pitprops, pulpwood, shipbuilding timber). The proposed Lower Ob' hydroelectric power project, even with the lower normal headwater surface now under consideration, would prevent economic development of the region by flooding valuable resource lands.  相似文献

For research on regional estimates of the water balance and future water-resource planning, it is important to determine the amount of water leakage downward across the base level, i.e. from the upper layers of the earth's crust drained by streams to the lower layers. The author presents a methodology based on water-balance equations that shows such leakage to be negligible in terms of the margin of error of precipitation and evapotranspiration records. It can therefore be assumed that the groundwater discharge into streams is practically identical with the recharge of groundwater reserves through percolation.  相似文献

Abstract. This article posits that individuation is a determining factor in making democratisation efforts workable or, where it is absent, ethnic conflict likely. Somalia serves as a case study. Since the Somali state has not been able to secure individuals' social welfare or their futures, citizens use genealogies, which chart trustworthiness, to construct social welfare safety-nets. There is also a moral dimension to genealogy. This is quite different from what occurs in the democratic West, where the state has guaranteed individuals a significant measure of social welfare security over time, and where identity can be considered situational. I argue that under conditions of uncertainty, such as have existed in Somalia, identity is not at all situational, but is fixed and fixes individuals in ethnic groups. The push to democratise can then lead to armed ethnic conflict.  相似文献

Periodically since about 1860 the debate about "The Ancient Economy" has raged vehemently as oikos controversy , Bücher-Meyer debate , primitivists versus modernists or simply as the Moses Finley debate . Therefore, Hopkins rightly remarked: "The ancient economy is an academic battleground. The contestants campaign under various colours--apologists, Marxists, modernizers, primitivists Even within schools, there are sects." This still seems to be the case, although the author of this article does not belong to any school or sect but is looking for an anti-ideological controllable scientific truth. Whatever that may be it is, certainly, a critical venture where "fraud" is at stake. In 1986, by symbolic accident the year of Finley's death, he dared to start a new period in the debate and at present the controversy with all its usual tricks seems at its zenith again. Did the bell toll for the last round in this beloved controversy? After 150 years of debate, one can never be sure about that, but we will try again. The subject matter is no less important than the question "to whom belongs antiquity?" or "for what purposes does one study its history or culture?" The following article wants to introduce the debate in a few sentences, question its present relevancy as the Moses Finley debate and provoke readers into another one.  相似文献

Uniquely among the world’s temperate forests, much of the vegetation of the Caspian forests is now endangered. But while deforestation has accelerated in Iran, these processes were actually underway in the nineteenth century. This article offers a brief introduction to the history of forest exploitation and concessions during the Qajar and Pahlavi periods, addressing actions taken by the Iranian state to protect and extend forest cover, but also the deficiencies of that legislation and the reasons for its failure. Though it is one of the most forested countries in the Middle East, Iran’s forests remain understudied. Existing scholarship mostly addresses the contemporary period; this paper extends the scope of our knowledge, offering a deeper history of forest exploitation in Iran.  相似文献

Two new covering problems are introduced. The partial covering P-center problem minimizes a coverage distance in such a way that a given fraction of the population is covered. The partial set covering problem seeks the minimum number of facilities needed to cover an exogenously specified fraction of the population within a given coverage distance. The problems are formulated as integer linear programming problems. Bisection search algorithms are outlined for the two problems. The search algorithm repeatedly solves a Lagrangian relaxation of the maximal covering problem. Computational results for the Lagrangian relaxation of the maximal covering problem and for the bisection search algorithms are presented on problems with up to 150 nodes.  相似文献

Revivalism and millennialism are important concepts that influence contemporary evangelicalism. However it was in the Great Awakening that Jonathan Edwards and select Scottish ministers first connected revivalism and millennialism together in a new evangelical print culture. Evangelical ministers used publications and personal correspondence to hypothesise that the current Atlantic revivals were signs pointing towards Christ’s millennial kingdom. The 1740s stands as a unique decade where evangelical ministers created an influential synthesis of revivalism, social progress, and millennialism. The revivalist and millennial synthesis was a harbinger of the evangelical future for religious movements in both the nineteenth and twentieth centuries.  相似文献

An American political scientist specializing in Soviet and post-Soviet foreign affairs outlines the highlights of Russian policy in the Caspian region from 1991 to late 2003. The paper discusses and analyzes the interaction among the five littoral states (Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan) in light of contentious disputes over the sea's demarcation, the routing of pipelines, and efforts to maximize oil and gas exports to the West. Noting instances of "gunboat diplomacy" used by Russia and Iran, as well as the American presence in the region after 9/11 and during the current war in Iraq, the author reflects on the Russian role as a stabilizing force in the region.
