The long-term dynamics and trend of the ion sink of the Amur River near Khabarovsk, Russia, in the winter low-water period were studied. The hydrological and hydrochemical characteristics of the main tributaries are given. The spatial heterogeneity of the distribution of mineralization along the length and width of the Amur is noted. The influence of large floods on the winter runoff of solutes has been established. The long-term increasing trend of ion sink in the winter low-water period due to hydropower construction is shown.

ulfates are the dominant ions among the major ones in the Amur region’s sewage. Therefore, the purpose of the research is to study the long-term dynamics of the content and runoff of sulfates in the Amur River in the winter low-water, based on the materials of Roshydromet for 1943-1976 and the author’s data for 1999-2019.Significant variations in the main areas were found due to both the diversity of natural conditions and anthropogenic influence in the areas of large cities and localities. The impact of the construction of hydroelectric power plants, significant economic changes in the Chinese part of the Amur basin, as well as the closure of pulp and paper and microbiological industries in the Russian part of the Amur basin on the long-term dynamics of the content and flow of sulfates is estimated. The maximum content of sulfates in the Amur River was observed after the accident at the Jilin chemical plant in China in December 2005. The influence of major floods on the increase in the flow of sulphates in the winter low-water was established.

A long-term study implemented in the Amur River basin enabled us to generate an updated checklist of 606 valid species in Chironomidae (Diptera) which are composed of 129 genera and six subfamilies, with 98 (17%) described new species belonging to 46 genera. Among the 98 recently described species, 46 ones (45%), were considered as possible endemics and sub-endemics. The numbers of species and genera by subfamilies is as follows: Podonominae (3 species; 3 genera), Tanypodinae (17; 9), Diamesinae (25; 11), Prodiamesinae (7; 3), Orthocladiinae (307; 57) and Chironominae (247; 46). The higher numbers of species (421 and 410, respectively) were recorded in the Lower and Middle parts of the Amur River basin, as compared with the Upper part of the basin. Most of the recorded chironomids (387 species, 67%) are Palaearctic in distribution, while others (191, 33%) are widely Holarctic. Species with Palaearctic distribution mostly have the following range types: East Palaearctic continental (23%); East Palaearctic continental-insular (20%); Palaearctic transpalaearctic (14%); Palaearctic amphi-Eurasian (10%).

Theoretical Overview

The article discusses the performativity of shopping tourism on the Russian-Chinese border using the terminology of M. Callon’s and his co-authors’ economy of qualities. The 2014 crisis has changed the parity of the ruble and the yuan, and has also changed the vector of cross-border tourism in the opposite direction. The authors show how observation of the residents of Blagoveshchensk regarding the purchases of Chinese tourists performs the perception of their social time and sends them “into the past”. They compared their everyday “here and now” knowledge with the knowledge accumulated during the operation of the cross-border local market. The usage of the language of the economy of qualities allows for the expansion of the boundaries of this concept for another type of market, that of the buyer’s market. We also ask about the dynamics of power in the wake of the assertion about the nature of market dynamics. The article consists of three main sections. The first section is a theoretical overview of the use of the concept of performativity in tourism research and the choice of the descriptive language for this empirical case. In the second section, we describe the “Chinese market” and trade practices before the 2014 crisis. The third section contains a reflection on the post-crisis changes and the processes of (re)qualification of goods and themselves. Empirical materials were gathered by the authors in the course of long-term studies in the twin-cities of Blagoveshchensk and Heikhe located on two banks of the Amur River, mainly through observation and interviews.

Interannual variations of the ice cover in the Tatar Strait are analyzed for the period from 1882 to 2018 and compared with the ice cover dynamics in the Okhotsk Sea. Synchronicity of the ice cover long-term oscillations in these regions is noted for the periods of 1894–1920 and 1985–2009, but it is not statistically significant for the whole time series. Current trend to the ice cover decreasing began in the Tatar Strait 5 years later than in the Okhotsk Sea. Besides, the cases of extremely low ice cover were observed in the Tatar Strait along the whole period of observations, whereas were happened in the Okhotsk Sea only in the period of warming since 1990s. Possible influence of the Amur River runoff on the sea ice forming in the Tatar Strait is discussed.

Представлены результаты наблюдений за содержанием аммонийного азота в воде р. Амур у г. Хабаровск в 2018–2019 гг. Максимальные значения установлены в правобережной и средней части русла в 2018 г. в начале ледостава (0.37 мг N/дм3), в 2019 г. в конце ледостава (0.32 мг N/дм3). Наименьшие значения зимой отмечены в левобережной части русла Амура из-за влияния зарегулированных рек Зея и Бурея. Показано постепенное снижение концентрации аммонийного азота в течение зимнего периода в 1.5 раза в 2018 г. и возрастание в 2.4 раза в 2019 г. Выявлено снижение концентраций в зимнюю межень 2018–2019 гг. по сравнению с периодом 2011–2013 гг. в 1.9 раза, что свидетельствует об улучшении качества воды р. Сунгари, а соответственно и Среднего Амура. В период открытого русла содержание аммонийного азота по сравнению с зимней меженью ниже и не превышает 0.1 мг N/дм3. Наибольшие значения наблюдаются в правобережной и средней части русла во время половодья и на подъеме паводков, сформированных в бассейнах рек Уссури и Сунгари. Показано, что на гребне катастрофического паводка, сформированного в Забайкальском крае в 2018 г., и очень сильного паводка в 2019 г. содержание аммонийного азота не превышало 0.05 мг N/дм3. Установлено, что содержание аммонийного азота в левобережной части русла, а в межпаводочный период по всей ширине Амура находится ниже предела обнаружения. The results of observations over the content of ammonium nitrogen in the water of the Amur River near Khabarovsk in 2018–2019 are presented. The maximum values were determined in the right-bank and middle parts of the riverbed in 2018 at the beginning of ice formation (0.37 mg of N/dm3) and in 2019 at the end of ice formation (0.32 mg of N/dm3). The minimum values were observed in winter in the left-bank part of the Amur riverbed due to effect of the regulated rivers of Zeya and Bureya. The gradual decline in the concentration of ammonium nitrogen 1.5 times during the winter season of 2018 and growth 2.4 times in 2019 are shown. The decrease in concentrations 1.9 times during the winter runoff low of 2018–2019 in comparison with period of 2011–2013 was revealed which gives evidence of the water quality improvement in Sungari River and, respectively, in the middle reaches of Amur River. In the period of free channel, the content of ammonium nitrogen is lower in comparison with the same during winter low-water level and does exceed 0.1 mg of N/dm3. The maximum values are observed in the right-bank and middle parts of the riverbed during high water and on the rise of floods formed in the catchments of the Ussuri and Sungari Rivers. It was demonstrated that in the top of the catastrophic flood formed in the Trans-Baikal Territory in 2018 and very strong flood in 2019, the content of ammonium nitrogen did not exceed 0.05 mg of N/dm3. It has been established that the content of ammonium nitrogen in the left-bank part of riverbed and in the peak-flood interval across the whole width of the Amur River is below detection limit.
