The Elkon uranium-ore region is located in the upper reaches of the river Aldan of the Republic of Sakha (Yakutia) within the Elkon mountain range. The resource potential of the massif allows us to consider it as the largest reserve source of uranium, gold and many other minerals in Russia and the world. During the development of deposits, environmental problems arise, for example, the quality of watercourses. In this regard, it is important to study the algal flora, which are natural indicators of the qualitative state of the waters and study of the hydrochemical state of water. The results of field and laboratory hydrobiological and hydrochemical studies of the rivers of the study area are presented. For the first time, an inventory of phytoplankton and phytoperiphyton algae in the study area was carried out. It was revealed that the basis of the taxonomic spectrum of algal communities is formed by the algoflora of the Bacillariophyta division, Cyanobacteria are less diverse, Chlorophyta and Ochrophyta are single. Phytoplankton in all studied rivers is extremely poor in terms of the number of species, abundance and biomass. Hydrochemical studies have shown that the content of the majority of normalized ingredients in the studied watercourses of the river Aldan in the area of the Elkonsky horst is below the maximum permissible concentrations. There is a high content of petroleum products. In summer, a high content of sulfides in the water of the Neprokhodimyi stream, which flows into the river Kurung, is noted. This circumstance, as well as the very low levels of phytoplankton at the stations of the Propadajushij stream, are the result of many years of mining in the past years of polluted mountain dumps in the Kurung river basin. In general, it has been determined that the qualitative state of the rivers in the Aldan river basin within the Elkon uranium ore region is due to the low-temperature regime of the climate and waters, as well as the location in the area of discontinuous distribution of permafrost. The work was carried out according to the state task on the topic “Vegetation cover of the permafrost zone of the taiga Yakutia: biodiversity, habitat-forming functions, protection and rational use” (scientific topic code: FWRS-2021-0023; within the framework of the draft state task (No. FWRS-2021-0014) of the program in the priority area of the Program of Fundamental Scientific Research in the Russian Federation for the long term (2021-2030).

One of the ways to obtain information about the cryogenic state of rocks by GPR is based on the analysis of the in-phase axes of signals reflected from local objects. On the images of GPR radargrams, similar in-phase axes are represented by hyperbolic curves. On the basis of their localization and refinement of the form, the speed of passage of an electromagnetic wave in the medium is determined. To refine the shape of the hyperbolic curve in the developed algorithm, methods based on the Hough transform were used. To optimize the performance of the algorithm, restrictions on the dimensions of the original and accumulator spaces are introduced. The boundaries of the original space were determined on the basis of previous studies on the detection of hyperbolic axes of common-mode signals. The dimension of the Hough space was reduced on the basis of a priori knowledge of the possible allowable speed of electromagnetic waves in the medium. As a result of the work of the created software, the speed of propagation of an electromagnetic wave in space above the local object and the real part of the complex relative permittivity are calculated, which makes it possible to determine the electrophysical properties of the medium. Testing of the developed algorithm was carried out on the results of field georadar measurements and synthetic data. The accuracy of the results of the algorithm was 98.6 %, which indicates the adequacy of its applicability for studying ice in permafrost layers.

The article provides brief information on the current state of healthcare in the Oymyakonsky ulus of the Republic of Sakha (Yakutia). Based on a survey of 440 respondents, the social conditions of local residents and those who have moved from this district to other settlements of the Russian Federation have been analyzed. The reasons for the migration outflow of the population from Oymyakonskii ulus of Yakutia to other settlements of the Russian Federation were reviewed. It was revealed that 42,8 % of the respondents are planning to move to another district or city, and 32,8 % periodically have a similar intention. The study showed that only 4.1 % of ulus residents are satisfied by the performance of local physicians, whereas among those who have previously left the region this indicator was 47.6 %. This fact is mainly due to the lack of specialized doctors and the high turnover rate due to the lack of housing for visiting specialists, difficult living conditions and harsh climate. According to the respondents, unsatisfaction with the quality of medical care and the desire to give a good education to children are the strongest predictors of the emigration of the local population outside the ulus. It is important to note that the vast majority of those who have left the district do not plan to return. All of the above shows that this problem requires comprehensive government assistance, especially in the field of health care.

The Basin of the Vilyui river is located on the territory of Western Yakutia, one of the most developed and industrialized parts of Yakutia, which is of great economic and strategic importance for Russia. The region is the center of the diamond mining industry of the Russian Federation, where primary and alluvial diamond deposits are developed, a cascade of hydroelectric power stations is located on the river Vilyui. This causes environmental and social problems, negatively affecting all components of the natural environment. It is necessary to study the stability of northern landscapes to technogenic impact and study the hydrobiological state of aquatic ecosystems, in particular, the state of the algoflora of watercourses. As a result of studying the degree of stability of landscapes in the basin of the river Vilyui to technogenic impact on permafrost and bioclimatic indicators, the degree of their resistance is determined. It was revealed that, according to the permafrost characteristics, the northern taiga open forest and haze landscapes are defined as predominantly weakly resistant, the middle taiga as medium resistant. The most unstable in terms of bioclimatic indicators were mountain-tundra landscapes, characterized by the coldest and most humid conditions. As a result of studies of the current hydrobiological state of the rivers in the basin of the river Vilyui determined the low development of phytoplankton and phytoperiphyton in the river Irelyakh, M. Botuobuya and in the upper reaches of the river Vilyui, consisting of a monotonous species composition of diatoms and green algae. The maximum average number of algae varies from 82290 cells/l to 20700 cells/l, the highest biomass was noted in one area and is 1.58 mg/l. The Shannon-Weaver biodiversity index varies by sampling points along the river. Vilyuy from 0.19 bits / copy. and 1.00 bits/copy. up to 2.40 bits/copy. According to the sanitary-biological characteristics, mass species-indicators of water saprobicity were identified, which indicates the III class of water purity, as moderately polluted. Thus, it was determined that the state of phytoplankton and phytoperiphyton is under the influence of the technogenic load of diamond mining and hydropower enterprises.The work was carried out according to the state assignment on the topic “Vegetation cover of the permafrost zone of the taiga Yakutia: biodiversity, habitat-forming functions, protection and rational use” (scientific topic code: FWRS-2021-0023; draft state task (No. FWRS-2021-0014) of the program in the priority area of the PFNI RF for the long-term period (2021-2030).

The article discusses the skidding concept, types and methods. In addition to specialized skidding tractors (cable skidder, grapple skidder, with a pack grip, and forwarders), modern single-machine complexes for harvesting wood according to Canadian and Scandinavian cutting technologies are presented. A theoretical analysis of tractor skidding performance is carried out, namely: the influence of the average skidding distance and soil conditions is estimated; an assessment of the impact of the type of logging and the taxation characteristics of the stand is given; the influence of soil and terrain conditions is estimated; the impact of the operator's qualifications and working conditions is evaluated. Based on the analysis of literature sources and production experience in the field of logging operations, the expediency of changing the operating mode of operators, as well as the use of special application software packages that allow real-time evaluation of the efficiency of the skidding tractor and its technical condition is justified. The influence of the category of soil conditions and the presence of non-operational areas in the cutting area on the average skidding distance, other conditions being equal, is shown. The work was carried out within the framework of the scientific school "Innovative developments in the field of logging industry and forestry" of the Arctic State Agrotechnological University.
