对间伐5年后的湖南会同杉木人工林生态系统碳贮量及其空间分配格局进行了研究。结果表明:（1）无论是间伐区还是对照区,单株杉木各器官的碳贮量以及乔木层各组分的碳贮量均与其生物量成正比,且均以树干的碳贮量最高,分别占单株杉木碳贮量和乔木层碳贮量的65.63%和64.99%以上,但间伐区单株杉木各器官碳贮量和乔木层各组分碳贮量的大小排序均与对照区有所不同。（2）间伐后,单株杉木的碳贮量增加了48.96 kg,增长了62.91%;但乔木层碳贮量下降了17.37%,减少了15.56 t.hm-2;林下植被碳贮量增加了1 399.42 kg.hm-2,增长了230.94%;杉木林生态系统的碳贮量减少了20.824 t.hm-2,下降了11.73%;其中植被层碳...

Carbon stroage and its spatial distribution in a Chinese fir plantation ecosystem thined five years were conducted by means of comparative studies in a controlled plantation ecosystem at Huitong Ecological Station,Hunan Province.Results show that carbon stroage of different organs of individual tree and different compositions of trees stratum were positive proportion with its biomass,and carbon storage of the trunk occupied greatest proportion,up to 65.63% of individual tree and 64.99% of trees stratum not only in the thinned but also in the co...
