| 中文摘要: |
| 为准确评估河北省生态系统碳储量,以河北省为对象,融合多源遥感与文献数据,应用InVEST模型Carbon模块对2015—2023年生态系统碳储量进行了时空动态评估,并基于碳交易市场均价解析了生态系统固碳服务价值。结果表明,林地碳密度最高,达190.95 t/hm2,是草地的1.73倍;研究期内河北省碳储量由1.468×109 t增至1.498×109 t,增幅2.13%,呈现“东北高、西北及东南低”的空间分布格局;固碳服务价值量呈现阶梯式增长,2020—2023年单位面积固碳价值增幅达1.38万元/km2,为2015—2020年增幅(0.21万元/km2)的6.57倍。研究成果为京津冀区域生态协同治理与碳汇市场建设提供了科学依据。 |

| This study integrated multi-source remote sensing and literature data to conduct a spatiotemporal dynamic assessment of ecosystem carbon storage in Hebei Province from 2015 to 2023 using the Carbon module of the InVEST model. Additionally, the value of ecosystem carbon sequestration services was analyzed based on the average market price of carbon trading. The results showed that forest land exhibited the highest carbon density of 190.95 t/hm2, 1.73 times that of grassland. During the study period, the total carbon storage in Hebei Province increased from 1.468×109 t to 1.498×109 t, representing a growth of 2.13%. Spatially, carbon storage displayed a pattern of “higher in the northeast, lower in the northwest and southeast”. The value of carbon sequestration services showed a stepwise growth. The increment in carbon sequestration value per unit area reached 13 800 yuan/km2 from 2020 to 2023, which was 6.57 times the growth rate (2 100 yuan/km2) from 2015 to 2020. This research provides a scientific basis for ecological coordinated governance and carbon sink market development in the Beijing-Tianjin-Hebei region. |
