Since the grain size is the most important factor in determining soil characteristics, our current research primarily aims to investigate dynamic changes of the soil fraction when exposed to freeze-thaw conditions. We observed two series of Moscow morainic clayey specimens （gQⅡm）： （Ⅰ） the original series, and （Ⅱ） the remolded series. We subjected each series of soil specimens to different frequencies of freeze-thaw cycles （3, 6, 20, and 40 cycles）, and we used granulometric tests to analyze both series before and after exposure to freeze-thaw conditions. As a result of our experiments, the granulometric compositions tended to be distributed evenly after 40 freeze-thaw processes （i.e., content of fraction for 0.1-0.05 mm was increased after 40 freeze-thaw cycles） because the division of coarse grains and the aggregation of fine grains were synchronized during the freeze-thaw process. The soil grains in both series changed bi-directionally. In the original series, changes of the sand grains were conjugated with the clay grains, and in the remolded series, changes of the sand grains were conjugated with the silt grains, because potential energy difference caused the division and aggregation processes to relate to the counteraction process. The even distribution of soil grain size indicated the state of equilibrium or balance. The granulometric compositions were altered the most during the sixth freeze-thaw cycle, because the coefficient of the intensity variation of the grain fineness （Kvar） had its maximum value at that time.展开更多

To characterize the habitat conditions of microbiota in the soils of different functional zones of the city, the acid-base conditions and the contents of exchangeable and water-soluble nitrogen, mobile heavy metals, and soluble salts were determined. The diversity of species of algal-cyanobacterial communities, the composition of the dominant species, the proportions of different ecological groups of diatom algae, the diversity of soil nano- and microfauna, and the abundance of colorless and colored mycelium in the urban soils were characterized. The analysis of these parameters showed that the degree of technogenic impact on soil microbiota decreases in the following sequence of functional zones of the city: industrial > traffic > residential > recreation.展开更多

Moscow City and Moscow Region （Moscow Oblast） are the parts of the Moscow Capital Region. According to the Constitution of Russia, adopted in December 1993, Moscow Region and Moscow City are two independent federal subjects of Russian Federation. The sustainable development of Moscow City and Moscow Region as an integrated regional economic and natural complex which plays the most important part in Russia＇s economy must be based on the integrated solution to the problems of environmental protection, social equity, and economic feasibility. The latest initiative of Russian Government concerns the creation of the Greater Moscow within the new borders of Moscow. Making the decision on the extension of the city limits and stimulation of the Moscow Agglomeration development provides the real way of resolution of the accumulated problems and provides enormous impetus to the sustainable development. The key task of the environmentally sound development of the Greater Moscow is to relieve the historical center of Moscow City; maintain the rational balance of built-up areas, natural and rural landscapes; ensure joint control of the urban development and economic activity; and create the favorable environment for the population.展开更多
