| 中文摘要: |
| 基于腾冲市2021年国家林草生态综合监测评价成果数据,采用生物量扩展因子法,对腾冲
市杉木林碳储量及碳密度进行估算及分析。结果表明,腾冲市杉木林生物量为2 742 418.29 t,碳储
量为1 426 057.51 t,平均碳密度33.37 t/hm2,其中,地类为乔木林地,优势树种为杉木,碳储量
为1 422 266.43 t,占主导地位,平均碳密度49.13 t/hm2;中和镇碳储量最大,腾越街道平均碳密度
49.18 t/hm2,与地类为乔木林地的杉木林平均碳密度相近。近熟林和成熟林的碳储量占腾冲市杉
木林碳储量的61.48%, 坡向对碳密度的影响不显著; 腾冲市杉木林单位面积蓄积量为134.65
m3/hm2,和顺镇单位面积蓄积量为319.28 m3/hm2,但幼龄林的单位面积蓄积量偏小,仅为52.23
m3/hm2。杉木种子退化,林分密度过大,枯枝病严重是造成腾冲市杉木林碳密度较低的主要原因。
通过良种选育、森林抚育、病害综合防治等措施,提高碳密度的潜力很大。 |
| 英文摘要: |
| Based on the national forest and grassland ecological comprehensive monitoring and evaluation
data of Tengchong City in 2021, the biomass expansion factor (BEF) method was used to estimate and
analyze the carbon stock and carbon density of Cunninghamia lanceolata forest. The results showed that
the biomass of Cunninghamia lanceolata forest in Tengchong City was 2 742 418.29 t, the carbon stock
was 1 426 057.51 t, and the average carbon density was 33.37 t/hm2. The dominant species was Cunninghamia lanceolata, with a carbon stock of 1 422 266.43 t, and the average carbon density was 49.13
t/hm2. Zhonghe Town had the largest carbon stock and Tengyue Sub-district had the largest carbon density of 49.18 t/hm2, which was similar to the average carbon density of Cunninghamia lanceolata arbor
forest land. The carbon stock of near-mature and mature forests accounted for 61.48% of the carbon
stock, and the effect of slope orientation on carbon density was not significant. The volume stock of Cunninghamia lanceolata forest in unit area was 134.65 m3/hm2 for Tengchong City, 319.28 m3/hm2 for Heshun
Town. However, the volume stock for young forests was as low as 52.23 m3/hm2. Seed degradation,
excessive stand density, and severe withering disease were the main reasons for the low carbon density.
Therefore, there was great potential to improve carbon density through measures such as breeding of
high-quality seeds, forest conservation, and comprehensive disease prevention and control. |
