Fine roots turnover in a broad-leaved Korean pine forest of Changbai mountain

Abstract

Abstract: Biomass productivity and annual turnover of fine roots in a broad-leaved Korean pine forest of Changbai mountain and their role in the allocation of net productivity are studied in this paper. The biomass of living fine roots is 5049,and that of dead ones is 1883kg. ha^-1 on an average. Annual turnover of fine roots is 0.96. Their annual production is 4860kg. ha^-1. yr^-1,being19. 40％ of total net productivity,and annual mortality is 2344kg. ha^-1,corresponding to 60％ of annual litter fallen. It is concluded that forest litter should include above-and under-ground litters.

Key words: Fine roots, Biomass, Production, Fine roots turnover, Forest litter
