Abstract. The road landscapes is the most significant type of anthropogenic landscapes. In this paper we pay much attention to the road-side landscapes, and their structural component -natural and anthropogenic ones. The said type of a landscape represents positive (barrows) and negative (excavations, ditches) forms of relief. The functioning of the auto transport complex is effective only if the necessary protection of automobile roadways and transport means is provided, that controls the unfavourable nature conditions, primarily, the drift of the roadway with snow and the lateral pressure upon the moving automobiles by strong gust of wind. The most effective measure for the development of the given problem is the arrangement of roadside windbreaks, which should represent a forestation of rational composition and proper construction of trees and shrubs for the functioning as wind-and snow-protective, and decorative plantations. The thickness of snow-deposit depends on the vertical density of forest belt. According to this characteristic the forest belts can be penetrable by wind, porous, and not penetrable by wind. The forest belts penetrable by wind have large clear spaces in lower part, while the crowns in upper part are rather dense. The forest belts of porous construction have even significant vertical clear spaces. The forest belts not penetrable by wind are of a high density all over the profile due to great number of shrubs and low-growing trees. In this regard, the urgent problem is the development of the methods for analysis of the information, and development of actual mapping layers, and, as a result, GIS technologies for mapping of road-side landscapes.Key words: road landscapes, barrows, excavations, wind-and snow-protective road-side windbreaks, GIS technologies, digital model of relief, space images, height matrix.УДК 521:634.958 ББК 43.47 ЛЕСОМЕЛИОРАЦИЯ ТРАНСПОРТНО-ДОРОЖНЫХ ЛАНДШАФТОВ С ПРИМЕНЕНИЕМ ГИС-ТЕХНОЛОГИЙ Глеб Александрович РулевФедеральный научный центр агроэкологии, комплексных мелиораций и защитного лесоразведения Российской академии наук, г.

Agricultural lands of the Russian Federation are intensively subjected to degradation and desertification as a result of irrational economic activity, which, against the background of unfavorable climatic factors, led to the destruction of natural ecosystems, degradation of the soil cover and ultimately to the creation of the unfavorable ecological environment. About 65 % of 130 million hectares of arable land, are exposed to water and wind erosion. Only by water erosion, 10 % of arable land lost 30–60 % of fertility and almost 25 % lost 10–30 %. As a result of deflation 25million hectares of agricultural land in the European part of the Russian Federation are degraded to varying degrees. The concept of the anti-degradation arrangement proposes to use environmental-economic geoinformational monitoring. Within the framework of this approach, the development of cartographic and mathematical models in three time environments is proposed: pre-agricultural, modern degraded, and certainly improved condition. The ecological and economic analysis makes it possible to synthesize information flows and analyze the most important degradation processes. The most important tool for implementing ther adaptive-landscape anti-degradation arrangement of agricultural landscapes is precision farming, which consists of several subsystems: decision-making, monitoring, agronomic techniques, specialized equipment, etc. Computer technologies and telecommunications allow to speed up and optimize production by combining technology and people, which helps reduce costs. Precision agriculture is impossible without using modern advances in collecting, processing and storage of various, often heterogeneous, agricultural information.

Purpose. Was to substantiate the geotopological paradigm of creating curtin plantings, taking into account the features of the soil and landscape cover of the south of the Volga Upland and northern Ergenes. Materials and methods. Study were carried out during 1988-2020 in the south of the Volga Upland within the Volgograd region. The test site was laid in the former OPH “Kachalinskoye” VNIALMI (now the land use “Kachalinskoye” of the Ilovlinsky district). The meso-and microrelief of the territory was analyzed on the basis of deciphering aerial photographs and ground - based studies. The soil and landscape cover was studied by a comparative geographical method. Based on the data of desk and field decoding with leveling of the terrain, schemes of curtin plantings on meadow-chestnut soils were proposed. Results. The work are obtained. Curtain plantings of dispersed linear-modular type curtain and size 14x22 m, number of trees - 46-50, rows - 6 with placement of 1-2,5 m. The creation technology was based on the author’s patent (SU 1692388). The taxational survey of 2020 showed that the preservation of the curtains of dispersed placement is - 7; of the modular-linear type is - 17, as well as individual tree biogroups have been preserved. The growth rates in the preserved kurtins were higher in the squat elm (Ulmus elfberry) 10.0 ± 0.12 robinia pseudoacia (robinia pseudoacia) 13.9 ± 0.9 m, lanceolate ash (Fraxinus lanceolata). At the same time, in plantings on chestnut saline soils, the height of stands varied from 5.5 m to 8 m. Conclusion. The technology of creating curtin plantings is reduced to the adaptation of the elements of creation to the intra-profile variation of forest suitability, i.e., the adaptation of forest-reclaimed work systems to the spatial heterogeneity of specific lithofacial and morphological conditions associated with the peculiarity of meso- and microrelief.
