摘要

[目的

]

明确广西壮族自治区平果县6种不同林种的乔木层、地被层、枯枝落叶层碳储量差异

为南方退耕还林工程区森林生态效益的评估提供数据支撑。[方法

]

以野外样地调查和数理为基础

结合基本统计方法进行分析。[结果

]

平果县不同退耕还林地乔木含碳率相差不大

除早熟桃之外

其他树种地上平均含碳率均在0.49到0.52之间。不同林分之间和相同林分的各器官之间均存在较大差异。6类退耕还林地的林地植被层总储碳密度由大到小依次为:八角26.864 t/hm

板栗23.120 t/hm

桉树22.863 t/hm

马尾松16.686 t/hm

早熟桃15.393 t/hm

任豆9.956 t/hm

退耕还林地植被层总碳储量为1.4374×10

t。[结论

]

平果县乔木层的平均储碳密度值远低于中国及世界各地森林平均储碳密度估计值。

Abstract

[Objective] To explore the carbon storage characteristics of arbor layer

herb layer and litter layer of six different trees of grain for green project in Pingguo County in order to provide the data support for evaluation of forest ecological benefit further. [Methods] Based on the survey of sample plots and mathematical analysis

combining with the basic statistical method

the characteristics of carbon storage were analyzed. [Results] The difference of carbon content between different arbor layers was little. In addition to the Amygdalus persica

the average carbon rates of other species on the ground ranged from 0.49 to 0.52. There were large differences between the various organs of the same stand

and the same situation for different stands. The decreasing order of carbon densities in different stands was followed as: Illicium verum 26.864 t/hm2

Castanea mollissima 23.120 t/hm2

Eucalyptus 22.863 t/hm2

Pinus massoniana 16.686 t/hm2

Amygdalus persica 15.393 t/hm2

Zenia insignis Chun 9.956 t/hm2. The total carbon storage of vegetation layer was 1.4374×105 t. [Conclusion] The average carbon density of arbor layer in Pingguo County was far less than the estimated value in China and other countries.
