摘要：以江西大岗山3种林分密度(2600~2800、3800~4100和5900~6400株/hm^(2))的毛竹林为对象,研究不同林分密度对毛竹林生态系统碳储量及其分配特征的影响。结果表明:1)3种林分密度下毛竹林生态系统碳储量为67.86~116.67 t/hm^(2),其中地上生物量碳储量、地下生物量碳储量、总生物量碳储量和总生态系统碳储量在不同林分密度间均达到显著差异(P<0.05),均表现为随着林分密度的增加而显著增大。2)毛竹林土壤碳储量在不同林分密度间无显著差异(P>0.05),但总体表现为先增加后减少的变化趋势,在中等密度林分下(3800~4100株/hm^(2))其土壤碳储量最大,为75.84 t/hm^(2),且随着林分密度的增大,土壤碳储量占总生态系统碳储量的比例也显著增加。3)地上生物量碳储量、地下生物量碳储量、总生物量碳储量和土壤碳储量均与总生态系统碳储量呈显著相关关系(P<0.05),其相关系数分别为0.71、0.75、0.72和0.80,但土壤碳储量与地上生物量碳储量、地下生物量碳储量和总生物量碳储量的相关性均未达到显著水平(P>0.05)。研究结果表明,适当增加林分密度有利于提高毛竹林生态系统的碳储量。
The moso bamboo forest ecosystem of three different forest densities(2600-2800,3800-4100 and 5900-6400 stems/ha)in Dagang mountain,Jiangxi province,are selected to study the effects of stand density on carbon storage and its allocation patterns in moso bamboo forest.The results demonstrate that:1)The total ecosystem carbon storage across the three densities ranges from 67.86 to 116.67 t/ha.Aboveground biomass carbon storage,belowground biomass carbon storage,total biomass carbon storage,and total ecosystem carbon storage differs significantly(P<0.05)among densities,exhibiting significant increases with rising stand density;2)Soil carbon storage does not differ significantly(P>0.05)among densities but displays an overall unimodal trend,reaching its maximum(75.84 t/ha)under the medium-density stand(3800-4100 stems/ha).Furthermore,the proportional contribution of soil carbon storage to total ecosystem carbon storage increases significantly with increasing density;and 3)Carbon storage in aboveground biomass,belowground biomass,total biomass,and soil all show significant positive correlations(P<0.05)with total ecosystem carbon storage(R=0.71,0.75,0.72,and 0.80,respectively).However,soil carbon storage is not significantly correlated(P>0.05)with aboveground,belowground,or total biomass carbon storage.The research results demonstrate that an appropriate increase in stand density is beneficial for enhancing carbon storage in moso bamboo forest ecosystems.
