Geoinformation analysis of the Kalach upland agricultural landscapes on the example of the "Solonka" research ground

Introduction. The active economic activities development related to the use of natural resources has a significant impact on nature-territorial complexes. Geoinformation analysis of the territory is one of the stages of obtaining primary information about the landscape components characteristics. Environmental protection measures are being developed and implemented on the data obtained basement.
Research object. The "Solonka" research ground with an area of 37614.5 hectares is located in the western part of the Nekhaevsky municipal district near the Solonka village.
Materials and methods. Within the framework of this study, the methodology is based on five stages: preliminary decryption (primary analysis of the study area); field research (building environmentally landscape profiles); decryption features extrapolation (unvisited territories decryption based on revealed at a key site signs and geomorphological characteristics analysis using the SRTM digital model); field control (visiting disputed areas); final mapping (construction and analysis of final maps based on previous research).
Conclusion. As a result of the Solonka research ground geoinformation analysis, it was revealed that the research area is under significant anthropogenic stress, since the share of plowing is 70.6% of the research ground, while the total forest cover is 9.54%. The research site geomorphological characteristics analysis was carried out. As a result, it was found that 93.9% of the territory has a slope of 0.5°-7°. The slopes exposure is mainly southern, northern, southwestern and western, which is due to the slope of the terrain towards ravines and balkas. The spatial data analysis made it possible to analyze area, average steepness and exposure of slopes on agricultural land, as well as to find out that deflation-hazardous territories account for 48% of the field area, and potentially erosivedangerous – 44%. The main part of the deflation-hazardous ploughs belongs to the northern (22%) and northwestern (23%) exposures. The most erosive fields are located on slopes of northern (18%), eastern (18%) and southwestern (18%) exposures.
