It has been experimentally found that the mono groups of Juniperus virginiana L. have less resistance to the natural and climatic factors, this is firstly due to increase in the height of biomass of the tree and secondly to application of loads in the form of a wind force, as well as an additional mass in precipitation. According to the results of diagnostics of the state and monitoring of sustainability of Juniperus virginiana L.plantings, the accident risk is estimated at 14% of the total number (585 units).

Studies conducted in different cities have shown that trees growing in urbanized areas reduce noise levels and cleanse the air of solid particles, ozone, sulfur dioxide, carbon monoxide, nitric oxide and other pollutants contained in car fumes, transport dust and generated by industry. The reaction to the influence of negative factors in woody plants is in disturbances in metabolism and biochemical composition, their general development also changes, and their population decreases. The indicators of disorders occurring at the cellular and tissue levels are more sensitive to the influence of negative anthropogenic factors in comparison with external manifestations. The research was carried out on woody plants: small-leaved linden (L. Tíliacordáta), horse chestnut (L. Aésculus); the soil. The research was carried out in 9 districts of Volgograd. The assessment of the state of woody plants was carried out by the visual method based on external signs. GOST methods were used to determine the concentrations of chemical elements in the foliage and soil of woody plants. Using physical and chemical methods, the concentrations of chemical elements in the soil and biomass of woody plants taken from the selected areas of the city of Volgograd were obtained, and the correlation between these indicators and the life state of woody plants was determined. The dependence of the indicators of the concentration of nutrients in the soil and the state and viability of woody plants was well traced. In general, the state of most of the woody plants of the city was healthy or moderately weakened. Such a high level of the life state is explained by the relatively young age structure of the studied plants, because at a young age woody plants are more resistant to negative factors of the urban environment. The revealed features of the life of woody plants in the city can be taken into account in the practice of city green building.

The state of Michigan has been constructing directional crossovers in the medians of boulevard roadways since the 1960s to alleviate the congestion and interlocking that were occurring at bidirectional crossover locations. The objective of this research is to investigate the safety benefits of divided roadway and directional crossover median designs. An investigation of the mean accident rates of roadways with boulevards compared to the mean accident rates of roadways with continuous center left-turn lanes revealed that there is a significant difference, with boulevard roadways having a lower mean accident rate for those Michigan roadways investigated. Investigation into the difference of the mean accident rates for boulevard roadways with medians of different widths indicated that roadways with medians greater than 9.15 m (30 ft) but less than 18.30 m (60 ft) had the lowest mean accident rate of the three median categories investigated. The difference was significant for most accident types when compared to roadways with medians less than or equal to 9.15 m (30 ft) and greater or equal to 18.30 m (60 ft). The investigation of the accident rates for boulevard roadways with directional and bidirectional signalized crossovers, while not conclusive, indicated that boulevard roadways with direction crossovers had a lower mean accident rate than boulevard roadways with bidirectional crossovers for signalized roadways.

State Of Affairs

The state of woody plants determines the viability of forests and environmental safety in urban environments largely. Therefore, scientific studies of the tree response as a complex biosystem on environmental factors changes are especially relevant due to the growing threat of environmental disasters (environmental pollution, active felling, etc.). Many modern methods for assessing the state of such complex macromolecular systems are verbal in nature due to the lack of non-destructive testing methods with controlled accuracy. The shortage of experimental measurements retards the development of modeling the state of trees and, consequently, the development of methods for predicting their response on the influence of external factors. The development of digital technology can change the current state of affairs in this sphere. In the report, within the framework of a systematic approach, the possibility of using digital technologies at analyzing the response of the state of woody plants on environmental factors changes has analyzed. The results of studying the flow of salt solutions in the xylem of tree trunks are presented to solve the problem. Based on experimental data, models are proposed that can become the basis of calculation systems for analyzing the state parameters of woody plants and predicting the occurrence of environmental disasters.

Abstract The purpose of this study is to identify the main trends in the agro-industrial complex development of the Russian Federation, substantiate the organizational and economic recommendations aimed at stimulating Russian agricultural production and enhancing of this economy sector competitiveness. An extensive corpus of empirical data reflecting the agro-industrial complex development in the Russian Federation in 2016-2020, as well as its place in foreign trade operations of the Russian Federation has been thoroughly studied in frames of this research. Using the tools of statistical data processing (sampling, observation, summary and grouping), the methods of econometric analysis, the dynamics of agro-industrial complex products manufacturing, the rate of the main indicators’ change, the place of agro-industrial complex in export-import operations of the Russian Federation have been revealed, the main indicators have been compared. The geographic conditions diversity of the Russian Federation, combined with a wide range of climatic features, the availability of land and water resources creates favorable conditions for productive agricultural activities. It has been established that large-scale agricultural producers dominate in agro-industrial complex of the Russian Federation. The directions of agro-industrial complex, in particular, crop production and cattle rising, are unevenly developing in the Russian Federation. The constituent entities of the Russian Federation, which administratively represent the Southern Federal and North Caucasian Federal Districts specialize mainly in the cultivation of grain and oilseeds due to the natural and climatic factors’ action. State authorities of the Russian Federation successfully implement the tools to stimulate agricultural production, in particular: preferential taxation regime, subsidies for lending to the agro-industrial complex economic entities from the state budget, leasing development, etc. The state support mechanism effectiveness can be intensified by using the organizational and economic tools substantiated by the authors.

The indicators of the sanitary condition of woody plants in the conditions of natural and artificial ecosystems of the Voronezh and Saratov Regions were established and analyzed. In suburban ecosystems of the research area, the state of woody plants is determined at the level of weak damage. In suburban areas of Balashov with the greatest economic and technosphere potential, woody plants reach an average (moderate) degree of damage. In remote relatively preserved ecosystems (control parameters), the state of these organisms corresponds to a weak ecological diagnostic criterion. According to the identified average arithmetic sanitary indicators in the Voronezh Region, the best condition is characterized by woody plants in the ecosystems of Novohopersk and Gribanovsky, in the Saratov Region - in Turki and Samoylovka. There were also significant differences in the arithmetic mean parameters of the sanitary condition of this group plants representatives differentiated by functional zones. The highest damage values are typical for woody plants in the urban ecosystems of industrial zones. The maximum danger to woody plants was observed within these zones in Povorino, Borisoglebsk, and Balashov with high-level average values of damage to these organisms. Significant concern is also caused by the defeat of the analyzed group of organisms in these cities as part of the ecosystems of the settlement zones. The results of the assessment of the sanitary condition of woody plants should be used as a scientific basis for landscaping, environmental protection and reforestation. Measures are proposed to improve the condition of woody plants in various types of ecosystems in the research area. According to the sanitary state of these organisms, it is possible to determine the limits of sustainability of ecological frameworks and differentiate the parameters of environmental comfort for the local population in different territorial categories.
