Abstract

Based on many years of research, the authors consider the features of mapping landscape of the Bolonsky nature reserve (Khabarovsk Territory, Russia), which has international statuses: “Lake Bolon and the mouths of the Selgon and Simmi Rivers” as Wetlands of International Importance and “Lake Bolon” as the Important Bird Area. The specific character of the landscape structure of the reserve (4 types of terrain and 23 landscape unit types) is studied, and plant associations of the mire and meadow-mire communities are studied for the first time. The list of leafy mosses of wetland ecosystems including 35 species was compiled. Due to the frequent recurrence of fires and floods, the need of long-term monitoring was justified and studies on key sites (in the scale 1 : 5000) has been started. The influence of pyrogenic factor on the landscape structure of the territory is studied based on the analysis of remote sensing data for 1996–2019 years.

Abstract

The results of the 2017–2019 years study of mires in the northwestern Arkhangelsk Region, including north- and south-facing slopes of the Vetreny Poyas Range and White Sea Lowland, are reported. The mires of the landforms of the model territory are described. Changes in the spatial structure of the plant cover of the mires were revealed. The Vetreny Poyas range was shown to be the southern boundary of mires of dystrophic South White Sea type. It is also the northern boundary of the aapa mires which spread from the south-facing slopes of the range and have some features indicative of a transition from Karelian to northeastern European types of aapa. The valley mires of the central ridge of the Vetreny Poyas are characterized by some distinctive regional features, and when creating large-scale zoning, the central ridge should be considered as an individual mire region. The Vetreny Poyas Range is one of the most striking examples of the effect of the orographic factor on the typological composition and geographic distribution of mires.

Abstract

Economy-geographical heterogeneity of the Republic of Kalmykia (South of the European Russia) is analyzed. Author divides it into economy-geographical micro-regions using the characteristics: population density and its character of settling, agricultural specialization, transport infrastructure development, location relative to the regional economic centers. The work presents an economy-geographical micro-zoning of Kalmykia on the base of ontological paradigm and better detailed local aspects comparatively with the preceding studies. The goal of the work is connected with socio-economy development of Kalmykia, particularly, prospects of renewable energy use that are different dependently on natural and economic conditions. The meso-region of Kalmykia is divided into five micro-regions: Western, Central-Eastern, South-Eastern, Northern, and Southern. The greatest differences are between Western and Central-Eastern micro-regions. The Western micro-region has the highest density of population, urbanization, and plant-growing economic specialization. The Central-Eastern micro-region has minimal population density, no large settlements and focuses on cattle breeding.

Abstract

Using the example of the Voronezh region as an old-developed flat region, methodical aspects of risk analysis are considered, including the identification, mapping and typology of landslides, identification the conditions of the landslide processes development and determination of the general characteristics of its hazard. Over 1700 landslides were revealed and mapped; a specialized geo-information system was compiled. The use of the GIS combined with the digital elevation model made it possible to determine the general regularity of spatial distribution of landslides, to clarify some parameters of its morphometry and territorial organization. Attention is focused on step-by-step approach to the assessment of landslide hazard and the identification of genetic types of landslides, which differ in structural, functional and dynamic features. The map of the landslide hazard levels of the landscapes of the Voronezh region has been compiled; it is based on a joint analysis of the density of landslide and the distribution of slope landscapes. The map made possible to identify regions with a low, medium and high degree of landslide hazard.

Abstract

The article discusses the environmental status of the unique oligotrophic Lake Turgoyak (Southern Ural). The age characteristics of the lake hollow and the maximum depths of the lake are specified. The dynamics of the ongoing changes at the lake ecosystem since the first scientific description of the lake in 1903–1912 until today is considered.. Anthropogenic impact on the lake is revealed. A gradual increase in water mineralization and a tendency to increase the concentration of total phosphorus were discovered. In the last 3–4 years, a steady decrease in the transparency of the lake waters has been observed; the lake has began to “bloom”. The transition of the lake to the oligotrophic-mesotrophic state is noted. The main reasons of the negative changes in lake ecosystem are the unsatisfactory condition of the sewage system, and the increasing recreational load on the coast and water area. The measures to preserve the lake were outlined, in particular, it was proposed to increase the conservation status of the lake.

Abstract

The article presents the results of spore-pollen analysis of honey samples of different origin, purchased at retail outlets in Krasnoyarsk in 2013 and 2015–2017. The obtained data showed that not all honey correspond to its geographical and botanical origin and do not match the parameters of naturalness. Honey are presented in Krasnoyarsk from Republic Bashkortostan, Altai region and the South of Krasnoyarsk region, less common is honey from the Khabarovsk region and Kazakhstan. The leading position in 2015–2017 in the number of quality samples of honey was occupied by the Altai territory. This figure has improved twice compared to 2013. Honey produced in the territory of Krasnoyarsk region and implemented in Krasnoyarsk in 2015 and 2016 by 20% (of the total number of samples studied) was artificial, pollen of honey plants was completely absent in them. Honey from Republic of Bashkortostan in 2013, 2015 and 2016 for 10-20% was artificial. The index of low-quality samples (with the absence of pollen grains) in all regions of honey production decreased from 33% in 2013 to 0% in 2017. Among all the honey sold in Krasnoyarsk, the samples of motley grass, sunflower, lime and acacia honey most corresponded to GOST.

Abstract

The foundation of paleolimnology, as a separate science in USSR/Russia, can be considered as the opening of the first Paleolimnology laboratory at the Limnological Institute, Siberian branch of Academy of Sciences of USSR (Irkutsk) in 1959. Gerbert Martinson can rightfully be considered as the founder of this research direction in Russia. During 60 years paleolimnology has been developed in USSR/Russia; new laboratories and research groups have been created, the Paleolimnology Commission has worked at the Russian Geographical Society, many conferences have been organized.
