The long-term grain requirements of the growing Soviet population are calculated. On the basis of the relationship between water use and grain yields by natural soil zones of the USSR, the authors show that the amount of water needed per unit of output declines with a growth of productivity, especially in the non-chernozem zone of the Soviet Union. It is therefore concluded that greater water savings might be assured by expanding grain production in zones with an adequate supply of natural moisture rather than by the use of artificial irrigation of arid lands. 相似文献

The aggregate effects of a variety of impacts generated by motor transport on the natural environment in the Upper Oka River basin are examined (through factor analysis) and maps of roadside pollution intensity are generated. The two factors identified, representing the effects of higher-order and local roads, respectively, provide a basis for regionalization of the Upper Oka basin according to the impacts generated by automobile traffic. The pattern of regional impacts identified, in turn, provides the basis for policy recommendations on how to reduce the level of roadside pollution and minimize other negative environmental impacts of road transport (translated by Jay K. Mitchell, PlanEcon, Inc., Washington, DC 20005). 相似文献

贵州省的城市生态环境问题 总被引:4,自引:0,他引:4
本文以贵阳等九座城市为例,从城市的自然环境和人类活动影响两方面,探讨贵州城市的生态,环境问题,以及协调人地矛盾的主要对策。全文分为以下三大部分:首先探讨城市的自然环境特征,说明贵州城市的形态结构,水土资源及城市扩展均受"喀斯特"环境的制约,其生态环境极为脆弱。表现在水土资源贫乏,平地少又很分散,地形封闭,旱涝和地貌灾害频繁等。第二论述城市的生态环境问题:以煤烟性空气污染,水体有机污染和交通噪声污染为主。SO2的污染极为严重,酸雨污染,城市河段及湖(库)污染普遍存在;4/5的城市交通噪声超过国家标准;1/2城市区域环境噪声污染严重。最后提出重建城市生态环境的主要对策。 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

Soviet population geographers have tended to study labor-resource problems at the level of major civil divisions, such as republics, krays and oblasts. There is a real need for investigating such problems at a more detailed regional level, down to particular rayons and urban places in which people live and are employed. Various types of economic-geographic investigations of labor-resource problems are suggested and a research strategy is proposed. The author notes that if population cannot be redistributed regionally in keeping with a given economic objective, economic plans may have to be revised on the basis of the actual labor resource situation. 相似文献

The evolution of the transport net within the BAM zone is examined in terms of three development stages. The first stage will involve the construction of the initial framework of the future transport net; aside from the BAM itself, it is recommended that consideration be given to the construction of a permanent motor road instead of the temporary construction road now envisaged. The second stage, in the author's view, should include the start of an extension of the Little BAM northward toward Yakutsk, as well as an oil pipeline (the author does not agree with the view that the BAM would replace earlier plans for a Trans-Siberian pipeline). The third stage would include a gas pipeline from the Yakutian fields to the coast; it is recommended that the gas line follow the alignment of the new railroads. No specific time frame is attached to the proposed three development stages. 相似文献

A paper devoted to demographic and labor-related issues in the development of the Kursk Magnetic Anomaly focuses on the need to improve labor productivity and services provision (particularly health care) in emerging industrial nodes of the complex. Such measures are expected both to promote labor retention and reduce labor inputs necessary to achieve the same amount of work. A key element of future labor strategy, given current low levels of natural increase within the region, is the recruitment and retention of labor from outside the region and the planned development of settlement to reduce negative environmental impacts (translated by Andrew R. Bond). 相似文献

全球视野下的价值链治理研究 总被引:1,自引:0,他引:1
在全球化背景下,以地方产业集群为发展模式的区域经济,其竞争力的提升需要在全球价值链中与区域外的经济行为主体积极互动,并实现升级。而价值链治理分析是经济地理学理论研究地方产业集群升级的关键。在这种研究视角下,本文以价值链治理为研究对象,首先界定了价值链治理的概念;并从理论上讨论了全球价值链治理模式的主要类型和演化过程;然后,进一步分析了价值链治理产生的原因、价值链治理的应用,以及价值链治理对地方产业网络升级的影响;最后,本文对国际现有的价值链治理理论进行了比较深入的讨论,并提出进一步研究的展望。 相似文献
