摘要

本文致力于研究河水的化学和生物特性以及它们之间的关系。我们检测了3个水体中地表水的水化学和细菌特性:Mezha河、Zapovedny村的一个池塘(特维尔州中央森林自然保护区)和顿河下游(罗斯托夫州)。细菌的生物多样性是根据它们在溶解有机物(DOM)上的生长来确定的。在能够在DOM上生长的浮游细菌中,DOM是唯一的碳源,顿河的主要物种是假单胞菌和Deinococcus,Mezha河的Pseudomonas和Janthinobacterium,池塘的Arcicella。就卫生和微生物指标而言,没有一个水体符合地表水卫生规则和条例1.2.3685-21。停滞水体中大多数研究元素和异养细菌的含量低于流动水体中的含量。所研究水域中异养细菌的浓度和活性与其中亲生物元素的含量呈正相关,与没有电流呈负相关。我们发现,由于共同的因素,细菌和化学指标之间存在很强的相关性:富营养化、领土的物理和地理条件特征,以及当前或动物废物的存在。

Hydrochemical And Bacterial Properties Of Water Bodies Of The East European Plain During Low Water Period
This paper is devoted to the study of the chemical and biological properties of river waters and the relationship between them. We examined the hydrochemical and bacterial properties of surface water in 3 waterbodies: the Mezha River, a pond in Zapovedny village (Central Forest Nature Reserve, Tver Oblast) and the lower reaches of the Don River (Rostov Oblast). The biodiversity of bacteria was determined based on their growth on dissolved organic matter (DOM). Among bacterioplankton capable of growing on DOM as the only source of carbon, the predominant species in the Don River were Pseudomonas and Deinococcus, in the Mezha River – Pseudomonas and Janthinobacterium, in the pond – Arcicella. In terms of sanitary and microbiological indicators, none of the waterbodies complied with the Sanitary Rules and Regulations 1.2.3685-21 for surface waters. The content of most of the studied elements and heterotrophic bacteria in stagnant waterbodies was lower than in flowing streams. The concentration and activity of heterotrophic bacteria in the studied waters correlated positively with the content of biophilic elements in them and negatively with the absence of a current. We showed that there is a strong correlation between bacterial and chemical indicators due to common factors: eutrophication, features of the physical and geographical conditions of the territory, and the presence of a current or animal waste products.

期刊介绍: Journal “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” is founded by the Faculty of Geography of Lomonosov Moscow State University, The Russian Geographical Society and by the Institute of Geography of RAS. It is the official journal of Russian Geographical Society, and a fully open access journal. Journal “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” publishes original, innovative, interdisciplinary and timely research letter articles and concise reviews on studies of the Earth and its environment scientific field. This goal covers a broad spectrum of scientific research areas (physical-, social-, economic-, cultural geography, environmental sciences and sustainable development) and also considers contemporary and widely used research methods, such as geoinformatics, cartography, remote sensing (including from space), geophysics, geochemistry, etc. “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” is the only original English-language journal in the field of geography and environmental sciences published in Russia. It is supposed to be an outlet from the Russian-speaking countries to Europe and an inlet from Europe to the Russian-speaking countries regarding environmental and Earth sciences, geography and sustainability. The main sections of the journal are the theory of geography and ecology, the theory of sustainable development, use of natural resources, natural resources assessment, global and regional changes of environment and climate, social-economical geography, ecological regional planning, sustainable regional development, applied aspects of geography and ecology, geoinformatics and ecological cartography, ecological problems of oil and gas sector, nature conservations, health and environment, and education for sustainable development. Articles are freely available to both subscribers and the wider public with permitted reuse.
