Spatial Principles of Territories Selection for Priority Development of Agroforestry Complexes

The creation of protective forest plantations on agricultural land is a long-term and capital-intensive investment aimed at creating sustainable agroforest landscapes. The purpose of the ongoing scientific research was to identify areas and create protective plantings, which will bring maximum effects. The methodology for achieving this goal is based on cartographic methods. Modern means of geoinformation modeling of territories and remote data make it possible to identify and follow the components of landscapes to obtain their quantitative characteristics. The result of the work carried out is a cartographic model of the study area, which allows for the analysis of the sufficiency of the number of existing forest plantations to ensure a sustainable development of the territories. The theoretical basis for determining the sufficiency of the number of forest plantations is the idea of the optimal forest cover of the territories. A review and analysis of existing points of view on the issue of optimal forest cover made it possible to identify the minimum parameters of protective forest cover. For the region of research, it is equal to 3%. The actual average value of the indicator of protective forest cover, calculated on the basis of the area of the entire study area, is 0.8%. The search for factors that determine the high efficiency of agroforestry measures made it possible to perform a differentiated assessment of the need for agroforestry measures. The ability to identify priority sites for the creation of protective forest plantations in these areas will bring maximum effects. The main principles of the search for areas of priority development are taking into account the geomorphological features of the study area, as well as the differences in the forest-growing properties of soils. The range of protective forest cover values for six geomorphologically different parts of the study area is from 0.6% to 2.7%. An analysis of the mutual arrangement of protective forest plantations and soil contours made it possible to identify the localization of spatial areas. When planning the creation of new protective forest plantations, priority is given to the most fertile lands, the indicators of protective forest cover of which are minimal.
