“…К геотопологии очень близко подошла ландшафтная экология [12,18,[20][21][22][23][24][25][26] В структуре почвенного покрова комплексы и пятнистость преобладают в Свеверо-Западном Прикаспии, а в почвенном покрове юга Приволжской возвышенности и Ергеней -катенарные сочетания [2,3,9,10,13,15], которые определяются гравитационным (латеральным) стоком вещества.…”

“…Геотопологическая парадигма создания куртинных насаждений должна быть реализована с учетом особенностей почвенно-ландшафтного покрова Северного Прикаспия и юга Приволжской возвышенности и Северных Ергеней. Функционирование древостоев лимитируется на исконно безлесных автоморфных светло-каштановых почвах -дополнительной влагозарядкой за счет метелевого снегонакопления и поверхностного стока [5,8,9,13,16]. На юге Приволжской возвышенности грунтовые воды не участвуют во влагообороте, глубина залегания 20 м и ниже.…”

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.

Modern global climate change manifests in an ever intensifying fashion, affecting anthropogenic and natural systems. Bioclimatic models predict significant shifts in biome boundaries, including a reduction in the forests’ proportion in the forest-steppe areas. This process can also affect carbon stocks. The aim of the work was to assess the impact of climate and its changes on the values and their changes of the phytomass’ carbon stocks of forest stands according to the data of repeated surveys of permanent sample plots. In the southern regions of the European Russia, 8 forests were selected and trial plots were set up. Repeated surveys were carried out on the test plots in 2010–2011, 2014–2015, 2019–2020. The carbon reserves of the living and the dead components of forest stands were calculated according to taxation characteristics. The litter carbon stocks were determined by the gravimetric method. The meteorological information analysis was carried out using data from the meteorological stations closest to the objects of study. Average annual temperature for 1991–2020 increased compared to 1961–1990. by 1.13°C, which is 2.5 times more than the global average. At the same time, annual precipitation decreased from 448.2 mm to 445.4 mm. The average value of the G.T. Selyaninov’s hydrothermal coefficient for May-September during the 1961–1990 period was 0.85, and 0.79 during the 1991–2020 period. The stock of the phytomass carbon in the studied forest stands varied from 38.5 ± 7.4 t C ha–1 to 270.6 ± 52.8 t C ha–1. Repeated surveys revealed both increases and decreases in phytomass carbon stocks, which ranged from –23.8 to 31.9 t C ha–1 over a five-year interval. The phytomass carbon stocks and climatic characteristics analysis revealed a statistically significant correlation with the HTC for May-September. However, comparison of changes in phytomass with changes in the average annual temperature, annual precipitation and HTC for May-September did not reveal significant dependencies. The absence of significant correlations between changes in phytomass carbon and climatic parameters’ changes can be determined by the forest ecosystems’ stability, which ensures the preservation of their functions over several years intervals.
