| 中文摘要: |
| 通过标准地调查和生物量实测,估算了云南省普洱市6种公益林典型林分(常绿阔叶林、针
阔混交林、思茅松纯林、黄竹林、灌木林地和宜林地)的生物量和碳储量。结果表明,不同林分类型
平均含碳率为48.66%,其中黄竹林含碳率最大(51.00%)。除宜林地外,普洱市公益林平均生物
量为205.16 t/hm2,常绿阔叶林生物量最大(320.52 t/hm2),其次是思茅松纯林(254.02 t/hm2) 和
针阔混交林(253.11 t/hm2)。在生物量分配方面,乔木层树种生物量占比较大,各林分乔木层树种
各器官生物量分配不同,常绿阔叶林为干>枝>根>皮>叶,思茅松纯林为干>枝>皮>叶>根,针阔混
交林为干>枝>根>皮>叶,黄竹林为干>根>枝>叶。在碳储量方面,常绿阔叶林碳储量最高(158.91
t/hm2),思茅松纯林、针阔混交林、黄竹林、灌木林和宜林地分别为123.96、120.88、73.15、53.58
t/hm2。研究结果为普洱市公益林建设和管理提供了科学依据。 |

| Through sample plot surveys and biomass measurements, this study estimated the biomass and
carbon storage of six typical forest stands of public welfare forests in Pu′er City, Yunnan Province, including
evergreen broad-leaved forests, mixed coniferous-broadleaf forests, pure Pinus kesiya var. langbianensis
forests, Dendrocalamus membranaceus forests, shrublands, and afforestation lands. The results
showed that the average carbon content rate across different forest types was 48.66%, with Dendrocalamus
membranaceus forests having the highest rate(51.00%). Excluding afforestation lands, the average biomass
of public welfare forests in Pu′er City was 205.16 t/hm2. Evergreen broad-leaved forests had the
highest biomass (320.52 t/hm2), followed by pure Pinus kesiya var. langbianensis forests(254.02 t/hm2)
and mixed coniferous-broadleaf forests (253.11 t/hm2). In terms of biomass allocation, the tree layer contributed the largest proportion. The distribution of biomass among different tree organs varied by forest
type: in evergreen broad-leaved forests, the order was trunk >branches>roots>bark >leaves; in pure Pinus
kesiya var. langbianensis forests, the order was trunk>branches>bark>leaves>roots; in mixed coniferous-
broadleaf forests, the order was trunk >branches>roots>bark >leaves; and in Dendrocalamus membranaceus
forests, the order was trunk > roots > branches > leaves. Regarding carbon storage, evergreen
broad-leaved forests had the highest carbon storage(158.91 t/hm2), followed by pure Pinus kesiya var.
langbianensis forests (123.96 t/hm2), mixed coniferous-broadleaf forests (120.88 t/hm2), Dendrocalamus
membranaceus forests (73.15 t/hm2), shrublands (53.58 t/hm2), and afforestation lands. The findings
provide a scientific basis for the construction and management of public welfare forests in Pu′er City. |
