Popis: 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.
