Abstract
It was elaborated a method of agro-ecosystem ranking for feijoa culture and forest ecosystem in one of regions of Western Georgia—Adjara subtropical humidified zone. On the basis of mineralogical and morphometric analysis (biometric parameters, beginning and end of growth, beginning of fruit ripening and mass ripening, frost resistance etc.) of feijoa culture (Feigoa selliowiana) and by multiple-factor approach we have evaluated culture’s rational disposition and optimal environment for development of land. The main accent was made on geomorphological (relief, inclination, exposition) and agro-climatic (sum of active temperatures, hydrothermal coefficient, temperature conditions, physical and chemical features of soil) factors. As a result of implemented zoning a landscape zone with agricultural resources potential and hypsometrical levels optimal for development of feijoa culture was revealed. During the research we also revealed corresponding agro-eco- system zone, compatible with feijoa zone, evaluation of quality of forest land and determination of ecosystem and its indicating character. For determination of compatibility of feijoa plants and distribution of forest ecosystem we have created a map of large-scale ecosystems and geo-information system. By Cartometric and geographic-informational analysis, it became possible to find information about types of forest ecosystems, areas occupied by them and their share in researched zone.
Highlights
One of the main priorities for economic development of Georgia are agricultural ecosystems, which are represented in diversity on the territory of Georgia (Agricultural Sector, 2011; Agriculture of Georgia, 2011) and it’s natural, as local nature preconditions optimal development of multi-field agricultural, including subtropical cultures.Further adaptation and intensification of agricultural resources require in-depth study of agricultural ecosystem and scientific analysis of intensity of ongoing natural processes and mapping, which shall promote system sustainability and keep natural balance, as well as introduction of cultural vegetation cultures and elaboration of successful agrotechnical measures

One of the main priorities for economic development of Georgia are agricultural ecosystems, which are represented in diversity on the territory of Georgia (Agricultural Sector, 2011; Agriculture of Georgia, 2011) and it’s natural, as local nature preconditions optimal development of multi-field agricultural, including subtropical cultures (in Western Georgia). For spreading of subtropical cultures in Georgia, especially against the background of global climate change, reaction of landscapes towards the problem is very important (Seperteladze et al, 2012; Elizbarashvili et al, 2014; Seperteladze et al, 2014a; Seperteladze et al, 2015a; Seperteladze et al, 2015b; Seperteladze et al, 2017; Seperteladze et al, 2019). The tendency of decrease of precipitations in humidified landscapes in Western Georgia, minor increase of air temperature and other negative natural processes should be considered during determination of plantation and frost resistance of citrus plants
