Abstract

Abstract: Biomass and productivity of a 7—year second generation of Chinese fir plantation were studied in Huitong ecological station of Hunan Province，and compared with the same aged stand of first generation．The results showed that biomass of the second gen-eration of Chinese fir stand decreased 14.18t/hm²,net productivity decreased 2.04 t/hm²·a than those of the first generation，and the decrease range reached 31.47％．Therefore more attentions should be paid by foresters．

Key words: Chinese fir second generation, Biomass, Productivity
