The development of Leningrad's suburban zone began mainly in the Soviet period with the growth of “dormitory” satellites of the central city. Many of the city's satellites perform the same industrial and cultural functions as Leningrad itself. The distribution of commuter areas is analyzed on the basis of winter commutation tickets. In addition to satellites, Leningrad has “associate” cities and towns that supply the central city with electric power and fuels but lack the commuting ties that differentiate true satellites. Further planning of the Leningrad suburban zone should take care not to saturate the suburbs with industry. It is more desirable to locate new plants in small and medium-size cities outside the suburban zone. 相似文献

The author analyzes the landscape-forming role of the snow cover by distinguishing four snow-cover periods in the winter season and investigating snow-accumulation conditions under various meteorological, relief and vegetation situations. The effect of the snow cover on ground frost, the wintering of plants and animals, the amount of surface runoff and soil erosion in the spring is analyzed for various combinations of conditions in each period. 相似文献

Since the fundamental work of William Morris Davis on a cyclic interpretation of landforms and of Walther Penck on slope development, no new conceptual approach has been offered in geomorphology until the appearance of Lester King's The Morphology of the Earth. But King's emphasis on the hypothesis of continental drift and on the process of pediplanation are judged inadequate for a full-fledged theory of geomorphology. As the new conceptual framework, the author prefers the morphostructural method of Soviet geomorphology, based on the relationship between tectonic elements and surface forms. 相似文献

Two Soviet regional planners test several spatial interaction models with particular reference to the Kuznetsk Basin (Kemerovo Oblast), the southern belt of West Siberia and a portion of the North Caucasus (Krasnodar Kray). Existing techniques, such as gravity and potential models, are found to work well in areas with relatively uniform settlement patterns, such as the steppe zone of Krasnodar Kray or the southern Ob'-Irtysh subregion of West Siberia, but not in areas with sharp contrasts in settlement patterns, such as the Kuznetsk Basin, where a linear highly urbanized belt is enclosed between sparsely populated mountains. In such contrasting settings, a combination of methods is required. 相似文献

The authors demonstrate that place names can help to reconstruct the changing geography of Moscow by identifying and localizing the stages of the city's growth, the development of its radial-circular layout, the absorption of adjoining villages, the distribution of handicrafts and industries, and the existence of hydrographic features and vegetative cover.

随着我国保障房建设速度的加快,保障房社区将对已有的城市社会空间结构带来深刻影响,其社会效应亟需深入探讨。本文以邻里效应为切入点,基于社区调研数据,采用因子分析、回归分析和质性研究方法,研究广州市保障房社区对周边社区的影响,以及这种影响的形成机制。研究发现,保障房社区并没有为周边社区带来负面的影响,也不存在"贫困同质化"的现象。然而,保障房居民与周边社区居民缺乏人际交往,其社会融合度也比较低。结果表明,提升保障房社区的社会认同度,消除不同社区居民相互间的隔阂,对构建和谐社区具有重要的意义。 相似文献
