This management policy is based on the characteristics of the forest itself and on management objectives. Numerous studies have shown that forest multi鄄objective management needs to include a multiplicity of spatial dimensions and temporal scales in order to meet the overall ecological,economic,and social benefits. Various factors need to be considered, e.g.,the definition of multi鄄 purposeforestry,the concept of forest multi鄄objective management,and the links and differences between traditional and modern forest multi鄄objective management in
