摘要/Abstract

摘要： 以我国江西、浙江两省的森林植被为研究对象,基于1999—2003年间第六次全国森林清查数据及收集的1030个亚热带森林样地文献资料,依据林分生长的经验方程,估算了两个地区森林2004—2013年的固碳潜力,并基于455个样点的调查数据研究了不同森林管理措施(纯林间种、间伐、施肥)对森林未来固碳潜力的影响.结果表明：第六次森林清查以来的10年(2004—2013)间,江西森林植被年均自然固碳潜力约11.37 Tg C·a^-1(1 Tg=10¹²g),而浙江省森林植被年均自然固碳潜力约4.34 Tg C·a^-1.纯林间种对江西、浙江两省森林植被固碳潜力影响最大,其次为间伐抚育,施肥的影响最小.纯林间种、间伐和施肥3种森林管理措施使江西省森林植被固碳潜力分别提高(6.54±3.9)、(3.81±2.02)和(2.35±0.6) Tg C·a^-1,浙江省森林植被固碳潜力分别提高(2.64±1.28)、(1.42±0.69 )和(1.15±0.29) Tg C·a^-1.

Abstract: Based on the sixth national forest inventory (1999-2003) and the investigation data of 1030 forest sampling plots in subtropical China collected from publications, and by using stand growth empirical equation, this paper estimated the carbon sequestration potential of forest vegetation under natural growth in Jiangxi and Zhejiang provinces in 2004-2013. In the meanwhile, the effects of three forest management measures, including interplanting, selective thinning, and fertilization, on the future forest carbon sequestration were explored by using the survey data of 455 sampling plots. In 2004-2013, the mean annual carbon sequestration potential of forest vegetation under natural growth in Jiangxi and Zhejiang could reach 11.37 and 4.34 Tg C·a^-1 (1 Tg=10¹²g), respectively. Interplanting could generate the largest carbon sequestration potential of forest vegetation, followed by selective thinning, and fertilization, resulting in an increase in the potential by (6.54±3.9) Tg C·a^-1, (3.81±2.02) Tg C·a^-1,and (2.35±0.6) Tg C·a^-1 in Jiangxi and by (2.64±1.28) Tg C·a^-1, (1.42±0.69) Tg C·a^-1, and (1.15±0.29) Tg C·a^-1 in Zhejiang, respectively.
