Agricultural aspects of the formation of ecological framework for an optimal agrolandscape

Abstract

The agrolandscape optimization problem has been analyzed through the formation and the structural and functional spatial organization of its ecological framework of the constituent stabilizing lands. Modern theoretical and practical proposals of the geographers, land surveyors and ecologists for the optimization of agrolandscapes refer to the definition of some median ratios of the areas of its constituent land within different taxonomic units. At the same time, no norms of the optimal correlation of land in agricultural landscapes recommended by the scientific research in Ukrainian agrarian landscapes have been introduced by the legislation of Ukraine. Requirements for the mutual spatial dislocation of the components of the optimal landscape are also not defined. Hence, the authors propose an approach to the spatial organization of the agrolandscape on the basis of assessing and taking into account the influence of climate regulation of afforestation and water bodies on other agrolandscape components. Formation of the ecological framework provides such a territorial location of arable lands that they end up in the zones of a permanent or periodic positive influence of forests and water bodies. The main result of the study is the development of a systematic approach to the formation of the ecological framework for the optimal agrolandscape on the basis of a substantiated transformation of the dimensions of its components and their rational mutual spatial allocation. The positive influence of forests and water bodies on the characteristics of the agrolandscape’s microclimate is evaluated as well.
