Abstract

Over the past twenty years, the term agro-ecological zones methodology (AEZ) has become widely used for global regional and national assessments of agricultural potentials. The AEZ methodologies and procedures have recently been extended and newly implemented to make use of the latest digital geographical databases, and to cope with the specific characteristics of seasonal temperate and boreal climates.

This report presents details of a companion model of AEZ that enables assessments of potential productivity of forest tree species. It is referred to a FAEZ.

The FAEZ methodology follows an environmental approach; it provides a standardized framework for the characterization of climate, soil and terrain conditions relevant to forest production and it uses environmental matching procedures to identify limitations of prevailing climate, soil and terrain for a range of tree species and assumed management objectives.

The model for the estimation of biomass increments is based on two well established and robust models: the Chapman-Richard biomass increment model, and the AEZ potential biomass model.

FAEZ includes an inventory of ecological adaptability characteristics as well as an inventory of specific ecological and environmental requirements for 52 boreal and temperate forest tree species. The natural resources inventory is based on the up-to-date LUC-GIS database of climate, soil, terrain and vegetation covering China, Mongolia and former Soviet Union.

Results of potential productivity for tree species in North, Central and East Asia are presented under three different sets of assumptions of forest resources management and exploitation, namely: conservation forestry, traditional production forestry and biomass plantation forestry.
