Vlasov V. Ecological Basics of Ampelolandscapes Formation.

The thesis deals with development of theoretical, methodological and practical basics for ampeloecological justification of agrolandscapes as the basis for optimization of placing vineyards in the Northern Black Sea region of Ukraine. On the basis of the performed retrospective analysis of the trends of grape varieties distribution and the condition of the viticulture it is necessary to revise the existing distribution of the Northern Black Sea region with a view to optimize the vine plantation placement on the variety level. Theoretical and methodological basics were proposed in order to solve the problems associated with the formation of ampelolandscapes as a subclass of agrolandscapes. To solve this problem, an ampelolandscape structure has been developed and algorithm to determine ampeloecotypes as the smallest by area and the most homogeneous by the set of optimal ecological conditions of sites for a particular variety as well as the algorithm of ampeloecological mapping of ampelolandscapes with the use of GIS technologies have been developed. Practical implementation of the work has been made in the Northern Black Sea region where thorough analysis of the ecological conditions with the use of 13 main points made to scale 1:10 000 and 5 plots made to scale 1:50 000 made the basis for ampeloecological distribution and the scheme for placing vine plantations on the variety level. The elaborated theoretical and methodological basics of ampeloecological assessment of the territory have been applied in the proposed methodological approaches to vine plantation cadastre development. Calculation of economic efficiency of the application of ampeloecological distribution of the territory has been made taking individual agroenterprises as the basis.
