Milyekhin P. Modern condition of erosion processes and soil conservation efficiency of forest stands in agrolandscapes of the South-East part of the Ukraine.

The objects of investigation - agricultural lands on north-eastern part of Ukraine and shelter forests on these lands. The aim of investigation - the development of methods of quantity assessment and forecast of inter-influenced factors, which precondition the erosion and productivity of arable lands likewise the shelter forest's anti-erosion efficiency. Methods of investigation and facilities - mathematical modelling of erosion rate and tillage productivity on the base of reference and statistical data, methods of forest melioration survey, field modelling of surface outlet absorption with shelter forests with using of outlet microplots. Theoretical and practical results - mathematical models to assess and predict the rate of erosion and tillage productivity, also the anti-erosion efficiency of shelter forest with different species composition. The newness of implanted - the complex of multifactorial mathematical models, built on the system level, for the global assessment of the rate of erosion and tillage productivity, and also for the definition of quantity interrelations in liquid and hard outlets in shelter forests. The scale of tree species influence on the slope outlet absorption is developed. The rate of implantation - the results of investigations was implanted in projects, devoted to the territory arrangement in few agricultural enterprises in Lugansk region. The branch of implantation - the optimisation of agricultural land's structure and designing of anti-erosion forest melioration measures in agroindustrial complex
