The study is focused on the specific features of ice regime in Amur lower reaches and the structure of ice surface in branches of different size and dynamic state. The main features of ice stratigraphy in different parts of the river have been identified, and ice cover characteristics have been found to show considerable heterogeneity across the channel. Quantitative data on the concentration of terrigenous material in the ice and its distribution within the ice mass have been collected. The amount of terrigenous material was estimated in the ice in Amur lower reaches, from where it is largely exported into the Sea of Okhotsk during spring ice drift. 相似文献

This study presents the landscape-geochemical characteristics of the Russian part of the Amur Basin and highlights the influence of geographic factors on the formation of the soil geochemical systems. The spatial variability of the element concentrations in the background soils is found to be a function of the mobility of the elements in organometallic compounds. The formation of the landscape-geochemical features is briefly reviewed. New approaches and principles of landscape-geochemical zonation are used to compile the map of the landscape-geochemical zoning of the Amur Basin on a scale of 1: 2500000, which shows the landscape-geochemical features reflecting the spatial variability of the element concentrations and the conditions of the element migration in the soils. 相似文献

The dynamics of river channel processes were analyzed in the region of complex floodplain-channel branching of the Amur River near Khabarovsk using remote sensing data of the Earth’s surface. Zones of steady accumulation and long-term erosion of the river channel are established within the Khabarovsk water junction over the period of 1964–2004. The main problems related to restoring the Amur River back to its initial channel were distinguished in the course of these works. A map of individual streams formed in the Amur River channel under the influence of large tributaries (the Sungari and Ussuri rivers) was developed. The importance of this map for forecasting the spreading of anthropogenic pollution in the channel of the Amur River is shown using the example of the emergency situation that resulted from the explosion at the chemical plant in the Sungari River basin (Jilin, China; November 2005). 相似文献

We examine the morphology and dynamics features of the river channels within the basin of the lower reaches of the Amur river
on spawning grounds. We report evidence that the spawning grounds tend to occur at definite elements of the river channel
as well as data on particle-size composition of alluvial deposits in autumn chum salmon (keta) spawning stretches. Factors
having a negative influence on the preservation of spawning grounds have been identified. 相似文献

Ice cover of the Amur River and its impact on channel processes 总被引：1，自引：0，他引：1
Special features of the Amur R. ice regime in its middle and lower reaches are discussed along with the role of river ice in bank erosion, transport of coarse fragmental material, bottom washout, and water flow redistribution among branches. Numerous and various consequences of the ice drift impact on the banks and floodplain, as well as the intensity of erosion processes in the Amur River channel during winter have been revealed. The water flow redistribution among the Amur River branches near Khabarovsk noticeably changed the ice regime, which was rehabilitated as a result of implementation of a complex of special measures. 相似文献

An outline is given of the career and scientific and teaching activity of the outstanding geomorphologist, professor of Moscow State University S.S. Voskresenskii, who created new scientific directions in the study of topography. He is rightfully given credit for geographical investigations of Siberia and the Far East in the latter half of the 20th century. 相似文献
