Abstract

Aim.To identify the degree of influence of the morphological heterogeneity of the territory on the ecological state of the agricultural landscape.MethodsThe study was conducted on an area of 608.5 hectares and a horizontal dissection factor of 8.36 km/km2. For the observations, distributed test pads measuring 10 m2 were used. On each type of facies, test sites were laid on arable land in triplicate. We used standard research methods using GIS. Existing thematic terrain maps were digitized and a digital elevation model based on a topographic survey of the terrain was created. Calculations and visualization of data are made using and based on the ArcGIS and Microsoft Excel software.Results.The degree of influence of the types of facies of the landscape area on individual criteria and indicators of arable land productivity (microclimatic indicators, water properties of the soil, elements of fertility) has been established. Spatial ecologically justified differentiation of types of tracts into facies types has been carried out.Main conclusions.The slopes of the northern exposure (I-IVn) have the highest ecological stability. They lead in the content of productive moisture, mobile phosphorus and potassium. The facies of the slopes of the southern exposure (I-IVs) lead by insolation, the content of humus and nitrate nitrogen. The content of heavy metals in the soils and wheat yield is higher on the southern slopes and second-order watersheds (IVn). The maximum productivity of 2.9 t/ha was obtained on the watershed type of facies (V). A close relationship was established (r = -0.72) between productivity and pH of soil, medium – with mobile forms of phosphorus (r = 0.59) and potassium (r = 0.84).
