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.
