Information on the thesis

The  thesis  is  devoted  to  structural  and  geographic  research  of  Precarpathians
agricultural landscapes that are paragenetic complicated landscape systems caused by
agricultural  using  of  territorial  systems  and  associated  with  them  by  material  and
energy  ties  natural  and  technical  structures.  In  the  paper  the  experience  of
anthropogenic-transformed  landscapes  studying  is  summarized,  methodical
approaches to their study are improved, the basic concepts are set out and algorithmic
model of agricultural landscapes is proposed.
The  component  structure  of  agricultural  landscapes  in  the  context  of  fourteen
natural areas is analysed. The value of agriculturally exploited and  natural lands in
the  region  is 2:1.  Agricultural  lands  occupy  about  59%, while  forests occupy  only
30% for foothill conditions of the region this parameter is quite low. One of the most
important environmental problems in the region is the excessive territory tillage. The
indicators of providing of Precarpathians population by agricultural land and arable
land are calculated.
The  features  of  the  region  water  regime  formation  are  investigated.
Precarpathians  soils  permeability  in  different  categories  of  land  is  reviewed.  The
snow  accumulation  features  in  agricultural  landscapes  are  clarified.  The  factors  of
development and intensification of erosion are reviewed. The dependence of eroded
land  on  agricultural  development,  arable  and  forest  is  quantified.  The  correlation
between  parameters  of  eroding  arable  land  and  arable  land  located  on  slopes  of
varying steepness is calculated.
Water-regulating role of forest lands in the Precarpathians river basins example
is reviewed. The modern structure of agricultural landscapes drained land deposits is
investigated  and  their  environmental  and  reclamation  role  is  estimated.  The
distribution  of  land  within  the  land  reclamation  systems  is  found.  The  negative
ecological processes developing on reclaimed land in the region are highlighted.
The  degree  of  anthropogenic  transformation  of  Precarpathians  territory  is
identified. The impact and value of land in the agricultural landscapes structure on
the  degree  of  the  territory  ecological  stability  is  conducted.  The  agricultural
landscape  zoning  is  done.  The  land  fund  regіon  structure  and  influence  of  human
activity on the development of erosion processes during 1950–2014 is studied. The
level  of  discrepancy  between  modern  land  distribution  and  ecologically  reasonable
standards is estimated. The optimal economic value and natural lands in Precarpathians
agricultural landscapes is calculated. The ways of restoring agricultural landscapes of the
region, covering four systems management – organizational and economic, agronomic,
agroforestry and hydraulic engineering are calculated.
