Carbon density of the Chinese fir plantation ecosystem at Huitong, Hu''''nan Province
湖南会同杉木人工林生态系统碳素密度

This study used permanent sampling plots data to investigate the carbon density of a Chinese fir plantation ecosystem. The results show that the carbon density of branches and leaves of different ages varied with the season in the following order: winter>autumn>summer>spring. The average foliar carbon density was 0.5044 gC·g~(-1) with a coefficient of variation of 2.08%. The average carbon density for branches was 0.4479 gC·g~(-1) with a coefficient of variation of 2.25%. The foliar carbon density in the ve...
