| 为了探明河池市碳储量变化情况并快速评估分级,以2010 年、2020 年土地利用数据为数据
源,研究基于InVEST模型的河池市森林碳储量估测模型的构建及其空间分布。结果表明,河池市
2010和2020年碳储量分别为219.1×106 t和234.8×106 t,呈增长趋势,碳储量在空间分布上表现
为北部、中部及南部较高,西北部和东部较低的空间特征;河池市固碳能力与土地利用类型变化密
切相关,林地对河池市碳储量增加贡献最大。根据河池市碳储量空间分布对全市碳储量的重要程
度进行分级,更为直观地展现全市碳储量在区位上的重要程度。 |

| In order to explore the carbon stock changes in Hechi City and quickly assess the grading, this
paper studied the construction of the forest carbon stock estimation model and its spatial distribution in
Hechi City based on the InVEST model, using the land use data of 2010 and 2020 as the data source. The
results showed that the carbon stock in Hechi City in 2010 and 2020 was 219. 1×106 t and 234. 8×106 t, respectively,
with an increasing trend. The spatial distribution of carbon stock showed the spatial characteristics
of higher in the north, central and south, and lower in the northwest and east. The carbon sequestration
capacity was closely related to changes in land use types, and forest land contributed the most to the
increase of carbon stock in Hechi City. The importance of carbon stock in Hechi City was graded according
to the spatial distribution, which more intuitively showed the location importance of carbon stock. |
