Geoinformation analysis of the location of state protective forest belts on the territory of the Saratov region

Introduction. The main function of state protective forest belts is environmental formation. Most of the areas of state protective forest belts are agricultural land. The field protection functions performed by the state protective forest protect arable lands from deflation and water erosion, which lead to the removal of the fertile soil layer. Most of the state protective forest belts forest plantations have reached a high age, at which there is a decrease in their safety. The study of the current state of the sites of state protective forest belts is an urgent task for the implementation of subsequent restoration work to improve the indicators of a favorable impact on the surrounding agricultural landscapes.

Object. The object of the study are three state protective forest belts in the Saratov region: two watershed – "Penza – Kamensk" and "Cherkessk – Chapaevsk"; one riverside on both banks of the Volga River – "Saratov – Astrakhan".

Materials and methods. The contours of the project area were mapped using the QGIS 3.32 geographic information system using ultra-high resolution satellite images of the WorldView 3 mission and the Google Earth service. The assignment of attributes to the state protective forest sections by soil types was carried out after vectorization of the soil map of the Saratov region at a scale of 1:2 000 000. "Weather and climate", respectively. Information about the presence of fires at the state protective forest sites was obtained from the Vega-science service.

Results and conclusions. Most of the sections of the Penza-Kamensk SPFB are located on chernozems, on chernozems with solonetzes, occupying an area of 3890.31 ha and 254.08 ha, respectively. Plots of the forest belt "Chapaevsk – Vladimirovka" in the amount of 3548.14 ha are located on chestnut soils, on dark chestnut soils 4963.80 ha, 1224.76 ha belong to chernozems, 105.03 ha lie on chestnut soils with solonetzes, 23 on chernozems with solonetzes, 07 ha, on alluvial 27.17 ha. The sections of the Saratov-Astrakhan state protective forest run through the following types of soils: chestnut – 121.75 ha; chestnut with salt licks – 363.89 ha; dark porridge – 1860.25 ha; chestnut salt licks – 7.61 ha; sands – 20.10 ha; chernozems 1876.25 ha; chernozems with solonetzes – 205.85 ha; chernozem solonetzes – 122.25 ha; other – 477.67 ha.
