STUDIES ON BIOMASS AND PRODUCTION OF THE LOEWR SUBTROPICAL EVERGREEN BROAD-LEAVED FOREST IN HEISHIDING NATURAL RESERVE——310MASS INCREMENT AND NET PRIMARY PRODUCTION
Abstract:Biomass increment, net primary production, and their allocation of the lower subtropical evergreen broad-leaved forest in Heishiding natural reserve were studied. Biomass increment of the forest amounted to 10.680t.hm-2a-1, among which trunk 6.127(57.37%), branch 2. 95(20.55%), leaf 0.514(4.18%), and root 1.844(17.27%).Increments in tree layer, shrub layer,and herbaceous layer were 8.786t.hm-2.a-1(82.27%) ,1.679(15.72%),and 0.215(2.01%) respectively.Vertical allocation of biomass increment was dominated by ...
