The effect of the regulated Zeya and Bureya rivers on the hydrological and hydrochemical regime of the Middle Amur are considered. An uneven distribution of the sum of ions across the width of the river is noted, with the greatest differences observed during the winter low-water period and the fewest differences occurring during the spring high-water period. It was found that, at the crest of the historical flood, the differences in the distribution of the sum of ions across the width of the Amur did not exceed 26 mg/L, and the maximum value in the middle of the river (up to 82.8 mg/L) was higher than during the 1998, 2002, 2009, and 2019 floods. The yearly largest sum of ions (132 mg/L) was recorded as a result of the removal of dissolved matter from the flooded farmland and urbanized areas in December at the beginning of freeze-up. The priority influence of the Sungari River on the temporal and spatial variability in ion concentrations in the water of the Amur River has been shown. An estimate was made of the ionic flow during the winter low-water period, spring flooding, and historical flooding, the decline of which in September was accompanied by the greatest removal of salts (6 644 000 t). Hydrocarbonate and sulfate ions; the calcium ion; and, to a lesser extent, the potassium ion and chloride ion made the main contribution to the formation of the ionic flow. The maximum share of the ionic flow of anthropogenic genesis (sulfates and chlorides) is observed in May during spring flood, when snowmelt dominates in the Amur water runoff, as well as of the hydrocarbonate ion and sodium ion in December, when salts are exported from moisture-saturated soils.</p>","PeriodicalId":44739,"journal":{"name":"Geography and Natural Resources","volume":"117 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138540801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The various aspects of the green economy and green development identified by them, including geographical, economic, social, and environmental ones, as well as their interconnections, are given. Green development is the economic development or development of a certain territory in which technogenic and anthropogenic impacts on the environment are minimized and the biodiversity of its landscapes and, in general, its green vegetation is preserved. It is suggested that green development should be treated as the first stages in achieving sustainable development. In order to implement certain incentives and governance, it is proposed to identify territories for green development. It is thought that one of their most important components is the existence of specially protected natural areas and their combinations, such as nature reserves, wildlife sanctuaries, national parks, protected areas, and significant areas of wildlife. A green economy should become predominant, ensuring a rise in production with a reduction in energy consumption and an improvement of the standard of living with reductions in resources used and technogenic pressure on ecosystems and biodiversity. Taking into consideration these criteria, as well as approaches to the natural and economic zoning on the territory of Primorskii krai, five territories (zones) were identified that hold promise for green development. The characteristic of the natural resource potential of the selected territories and of their existing specialization is provided, and the priority types of economic activities that are compatible with green development are determined.

It has been established that the probability of origin and development of the related anomalous processes and disasters was included in the relation of continentality and oceanicity. Many peculiarities of the dynamic of the geosystems and anomalous processes are clarified. For example, the number and intensity of anomalous processes increase: the frequency of storms and storm surges grows and the washway of the seashores and submarine nearshore slope, etc., intensifies. As a result, the strip of active interpenetation of the continentality and oceanicity, emphasized currently by the mottled alternation of the forms, processes, and formations (in the goltsy zone of the middle altitudes, the formation of rock glaciers and cryogenic sorting of grounds and ice blisters and more in the valleys of mountain rivers) that are “strange” in origin, becomes displaced to the east, to the coastal zone. The repetition frequency of the extreme processes and their effect on the geosystems in the continental margin of the Russian Far East have increased in recent decades. It has been established that the use of continentality and oceanicity characteristics allows us to determine the ecological risks and has the high potential of application in solving urgent problems.

It is shown that, in order to solve problems, it is necessary to have an idea of the patterns of functioning of these complexes under different economic policies of the states engaged in water use. Based on the long-term practices of interstate interaction, it is noted that the more states there are intersecting a transboundary watercourse, the more difficult it is to implement measures of integrated water resource management. The main factors of the occurrence and exacerbation of water use conflicts in transboundary river basins are identified. An analysis of the institutional and legal formats of interaction between states and water users has been carried out. The predominance of bilateral agreements and the lack of interest in the development of universal multilateral treaties are noted. From the standpoint of structural and functional integrity, the expediency of considering transboundary river basins from the standpoint of the basin principle is substantiated. It is concluded that, under conditions of significant anthropogenic fragmentation of transboundary river basins, a quasi-integral natural–social geosystem of the regional level is formed. It is noted that, taking into account the complexity and inconsistency of the “transboundary river basin” category, a universal approach is needed for solving the problems of interstate interactions that makes it possible to combine the basic principles (limnological, institutional–legal, and basin principle) into a single conceptual model. Such tasks can be successfully solved through implementing the main provisions of a systematic approach, the application of which will make it possible to determine the individual characteristics of a transboundary basin and synthesize them into a single whole, develop integrated water resource management schemes, coordinate joint actions of water-user states, and move from the private solutions of problems of interstate interaction to complex problems.</p>","PeriodicalId":44739,"journal":{"name":"Geography and Natural Resources","volume":"3 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138540820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main features in the relief formation of the depression are outlined and the principal factors are determined. This study has revealed the predomination of fluvial, lacustrine, and cryogenic processes in the modern morphogenesis of the depression. Special attention is paid to the study of lakes. Modern methods of bathymetric surveys are used to determine the main parameters of the basins of the major lakes in the depression: Amut, Malan-Zurkhen, Balan-Tamur, and Churikto. It has been revealed that ancient glaciers and tectonic movements were involved in the formation and configuration of the lake basins. The current shape of the shore zone depends on the geological structure, in which a special role is played by thermoabrasion and thermodenudation. Since the study area is assigned to the Dzherginskii State Nature Reserve with its principal mission to preserve natural systems, landscape investigations have been performed. The medium-scale map of the depression and surrounding mountains is based on the concept of geosystems by Academician V.B. Sochava and compiled with the use of classical methods of studying the plant cover complemented by images taken by an unmanned flying vehicle and data from remote sensing of the Earth. The salient features of the modern status of landscapes in the study area are highlighted. The main role in the structure of the landscapes is played by mountain–taiga and mountain–depression larch geosystems with mature moss–lichen cover. At higher hypsometric levels, a greater area is occupied by subshrub–lichen sparse larch communities.</p>","PeriodicalId":44739,"journal":{"name":"Geography and Natural Resources","volume":"3 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138540810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A high-precision digital elevation model with a horizontal resolution of up to 10 m has been developed for the bottom surface in the area of the volcano. By analyzing the resulting model, it is possible to update the morphometric parameters of the underwater structure under consideration and prepare a detailed morphological description. It has been found that the volcanic edifice consists of several ridgelike parts located on the wings of the Gidratnyi Fault and crossing it. A canyon-shaped and curved in plan 800-m wide valley was mapped to the southeast of the fault. A graphical representation of backscatter data with separation by types of sedimentary layers is created via a comparison of the intensity of the reflected signal and expected mathematical model values. Based on the results of data analysis, it has been established that the mud volcano mainly consists of clay with the possible inclusion of relatively large fragments (up to 10 cm). Presumably there are also large fragments on the bottom surface around the volcano; however, fine-grained fractions (sandy, clayey, and silty) are dominant. A three-dimensional visualization of the water column data is presented for the study area with the detected outcrops of gas in the form of two gas flares with the observed heights of 800 and 700 m. According to a statistical sample of the values of the reflected signal amplitudes, the intensity of gas release in the flares differs by approximately 7 times.
