摘要
采取野外调查取样和实验分析相结合的方式,应用生物量经验模型法研究山东大学侧柏林区生态系统区域尺度上碳储量、碳密度及分布特征。研究结果表明:植被层平均含碳率为0.489,其中,乔木层含碳率为0.496,灌木层含碳率为0.554,枯落物层含碳率为0.461;侧柏林植被生物量为41.9t/hm2,碳密度为20.5t/hm2,仅为全国柏木林平均水平的63%,明显偏低;碳密度空间分布特征表现为乔木层>枯落物层>林下植被层;全市侧柏林碳储量为9.86万t。
Using field investigation sampling and laboratory analysis,we studied the carbon storage,carbon density and distribution characteristics of Chinese arborvitae on the spatial scale by biomass empirical model.The results showed the average carbon content rate of the vegetation layer rate is 0.489,among which,the carbon content rate of tree layer is 0.496,the carbon content rate of brushwood layer is 0.554,the carbon content rate of litter layer is 0.461.The biomass of Chinese Arborvitae is 41.9t/ha,and the carbon density is 20.5t/ha,only 63% of nationally cypress forest,obviously lower.The spatial distribution of carbon density is tree layer> litter layer>undergrowth layer.The carbon storage is 98 600t.
