Abstract:

Based on field investigation,biomass and carbon density of forest communities in Shanxi Huoshan Mountains were estimated by using the biomass expansion factor(BEF)continuous function method and its distribution pattern and influence factors were analysed.Results showed that the average unit area biomass and carbon density of forest communities in Shanxi Huoshan Mountains were 58.00 t/hm 2 and 29.46 t/hm 2.The average unit area biomass(62.35 t/hm 2)and carbon density(31.17 t/hm 2)of Quercus wutaishanica forest were highest in comparison with that of the Pinus tabulaeformis forest(58.44 t/hm 2,30.10 t/hm 2).Pinus bungeana forest(56.58 t/hm 2,28.79 t/hm 2),Platycladus orientalis forest(54.86 t/hm 2,27.91 t/hm 2)and Robinia pseudoacacia forest(53.78 t/hm 2,26.74 t/hm 2).The correlation coefficient between altitude and biomass was 0.65 and the correlation coefficient between altitude and carbon density was 0.68,which all showed significant positive correlation(P<0.01).The relationships between slope,slope aspect,slope position and biomass,carbon density were not significant.Altitude was the main influence factor on distribution pattern of forest biomass and carbon density in Shanxi Huoshan Mountains.

Key words: Shanxi Huoshan Mountains, forest community, environmental factors, biomass, carbon density
