摘要

Changbai pine (Pinus sylvestris Var. Sylvestriformis) is an endemic and important tree species in Changbai Mountain. There were only 63 plant species in Changbai pine plantation, where hemicryptophyte was dominant(39.68/100). Simpson diversity index was 0.87, Shannon-Wiener diversity index was 2.96, and evenness index was 0.82. Community structure were divided into three layers tree layer, shrub layer and herb layer. The total biomass and net production were 111.982 t/hm~2 and 8942.80 kg/(hm~2·a) respectively. The total biomass for tree, shrub and herb layers were 106.150, 2.230, 2.264t/hm~2, accounting for 94.79/100, 1.99/100, and 2.02/100, respectively, and net production for those were 7465, 223, and 1182 kg/(hm~2), accounting for 83.47/100, 2.49/100, and 13.22/100 of the total respectively.
