Abstract: It was elaborated a method of agro-ecosystem ranking for feijoa cultureand forest ecosystem in one of regions of Western Georgia—Adjara subtropical humidifiedzone. On the basis of mineralogical and morphometric analysis (biometricparameters, beginning and end of growth, beginning of fruit ripening and massripening, frost resistance etc.) of feijoa culture (Feigoa selliowiana) and bymultiple-factor approach we have evaluated culture’s rational disposition andoptimal environment for development of land. The main accent was made ongeomorphological (relief, inclination, exposition) and agro-climatic (sum ofactive temperatures, hydrothermal coefficient, temperature conditions, physicaland chemical features of soil) factors. As a result of implemented zoning alandscape zone with agricultural resources potential and hypsometrical levelsoptimal for development of feijoa culture was revealed. During the research wealso revealed corresponding agro-eco- systemzone, compatible with feijoa zone, evaluation of quality of forest land anddetermination of ecosystem and its indicating character. For determination ofcompatibility of feijoa plants and distribution of forest ecosystem we havecreated a map of large-scale ecosystems and geo-information system. ByCartometric and geographic-informational analysis, itbecame possible to find information about types of forest ecosystems, areasoccupied by them and their share in researched zone.
