Abstract
The purpose of the study was to determine the regularities of the spring formation elements of water balance and soil erosion under the influence of a set of anti-erosion techniques based on long-term observations (1964-2020). The research object was created in 1964 on the land of the farm “Vyazovsky”. The complex of anti-erosion techniques consists of two forest strips 300 m apart, reinforced with ditches. The inter-lane space was developed by crop rotations and pasture with the use of mulched crevices to combat, with silting and ice content of cracks. The dose of straw sections at a distance between the slits of 1.4 m – 4.8 t / ha. Forest belts accumulate snow by 33.3% more than open agricultural landscapes, and in low-snow winters, the effect of snow deposition increases by another 20%. Long-term studies of spring runoff on land in the steppe of the Volga upland allowed us to recommend the appropriate values of 10% probability of excess for creating soil protection complexes from erosion: moldboard ploughland – 25 mm, moldboardless ploughland– 47 mm, winter crops и grass pastures – 65 mm. The content of southern chernozem with A+B <0.5 m at the permissible level of erosion equal to 0.3 t / ha is possible when a complex of anti-erosion forest reclamation and agrotechnical techniques is introduced into the technology of crop cultivation. Regression and correlation analysis found that the spring runoff coefficient and spring soil erosion depend on the amount of water reserves in the snow and the degree of protection of land from erosion by anti-erosion techniques by 92-99%.

Published: April 2021

Abstract
Floods are characterized by non-periodic and short-term rise in the water level in the river, which can lead to catastrophic consequences and large material damage. The aim of this work is to study in detail the components of the water balance of the river basin, which affect the amount of flood runoff. The objects of study are the rivers of Eastern Siberia Selenga and Onon rivers. For the work, materials of long-term observations of the hydrometeorological network of the Trans-Baikal UGMS were used, as well as the database of the GPCC atmospheric precipitation climatology center. The methodological basis was a comprehensive hydrological and geographical analysis of the processes of flood runoff, namely the water balance method. In the course of the study, a geographical analysis of the factors of floods in the conditions of the steppe, forest-steppe and taiga zones of Eastern Siberia was carried out. For a thirty-year period of hydrometeorological observations in the basins of the Selenga and Onon rivers, graphs of changes in water discharge over time (hydrographs) were constructed and genetically related values of flood runoff and flood-forming precipitation were calculated. The unity of landscape characteristics and climatic features determine the hydrological indicators of the river in its different sections, which gives an overall picture of the hydrological indicators of the river network as a whole. According to the ratio of the maximum discharge of water of various origins, spring floods and summer floods, in the basin of the river Selenga and Onon groups of rivers were identified according to the prevailing origin of maximum flow. For the rivers of the Selenga and Onon basins, fluctuations in river runoff and atmospheric precipitation were investigated, and their relationships with the characteristics of atmospheric circulation were established. Difficulties in the analysis of hydrometeorological processes for the considered river basins are their transboundary location.

Published: April 2021

Abstract
The paper presents the results of a study of the effect of benzo(a)pyrene on the activity of hydrocarbon-oxidizing soil bacteria of the genus Pseudomonas and Rhodococcus. The objects of research are samples of agrosod-calcareous soil, exposed to oil pollution, located near an oil refinery with an increased concentration of benzo(a)pyrene. Studies carried out over three years from 2017 to 2019 showed that in all soil samples that are exposed to oil pollution, the concentration of benzo(a)pyrene exceeds the MPC. It was found that an increase in the concentration of benzo(a)pyrene in the soil is accompanied by the suppression of the activity of hydrocarbon-oxidizing bacteria of the genus Rhodococcus and Pseudomonas. The presence of an inverse relationship between the content of benzo(a)pyrene and the number of microorganisms was confirmed by correlation analysis carried out using Spearman’s rank correlation coefficients (ρs) and τb-Kendall. The data presented in this work can be used in organizing bioremediation of oil-contaminated agrosod-calcareous soils. In the case of a high level of soil pollution with oil products, for its effective restoration, additional support for the activity of hydrocarbon-oxidizing microorganisms is needed, including by loosening.

Authors: Belik A A , Kokoreva A A , Ezhelev Z S 
Published: April 2021

Abstract
The water assembly of the MACRO model, making allowance regarding the double porosity of soils, was parameterized according to experimental laboratory data and tested according to the results of studying the water regime of sod-podzolic middle loamy soils of large lysimeters of MSU. Testing of pesticide migration models is necessary to improve forecast accuracy and justify their use. The analysis of the sensitivity, estimated from the data on the lysimetric runoff at the lower point (1.5 m) of the soil, showed that the WRC parameters are the main physical support of the models, which sets the forecast accuracy. These are the parameters that must be used to customize the model. The MACRO model has showed itself better at describing lysimetric runoff during the growing season by taking into account the fast flows along macropores and fissures that occur during periods of intense precipitation in the model than the models previously used.

Abstract
The present research is devoted to the assessment of the ecological conditions of the “Opukskiy” reserve (Republic of Crimea, RF) under the conditions of increasing anthropogenic pressure. The development of ecological tourism on the territory of natural reserves is one of the vectors of development of the system of protected areas in Russia. However, this is associated with an increase in anthropogenic impact on these objects. To correctly account for the permissible anthropogenic pressures, strict monitoring measures are required to control environmental conditions. The work is based on the material obtained over three years (2017– 2019) in the framework of scientific practices for students of St. Petersburg State University. As a result of the work, a map of the distribution of heavy metals in the soils of the reserve was compiled. The regularities of migration of pollutants in soils are described and the vulnerability to pollution is substantiated. The stages of anthropogenic digression of plant communities have been determined. The consequences of tourism development are assessed. Recommendations for the regulation of tourism are given.
