摘要:

以山西霍山森林植被为研究对象,在野外样方调查的基础上,运用生物量换算因子连续函数法对霍山主要森林类型的生物量和碳密度进行了估算,并分析了影响生物量和碳密度分布的主要影响因素。山西霍山森林群落的平均单位面积生物量和碳密度分别为58.00t/hm 2和29.46t/hm 2。其中,辽东栎林具有较高的生物量(62.35 t/hm 2)和碳密度(31.17 t/hm 2),其次为油松林(生物量58.44 t/hm 2,碳密度30.10 t/hm 2),白皮松林、侧柏林和刺槐林的生物量和碳密度较低。海拔与生物量、海拔与碳密度之间的相关系数分别为0.65和0.68,均表现出极显著的正相关(P<0.01);坡度、坡向和坡位与生物量和碳密度的相关性均未达到显著水平。海拔是影响山西霍山森林生物量和碳密度的最主要环境因子。

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
