| 中文摘要: |
| 为探究河北省生态系统生产总值的时空演变规律,对区域生态保护与可持续发展政策制定提供科学依据,基于2015、2020、2023年生态环境与社会经济数据,采用GEP核算体系,定量评估典型的生态系统服务价值,并进行空间演变分析和驱动机制分析。结果表明,2015—2023年,河北省GEP总量呈现先降后升的动态波动趋势,由4 460.01亿元降至4 121.24亿元后回升至4 214.54亿元;水源涵养服务与固定二氧化碳服务构成生态系统服务价值主体;生态系统服务呈现显著时空分异,燕山—太行山区生态调节功能显著;河北省GEP空间分异与自然地理、政策调控及人类活动密切相关。 |

| This study investigated the spatiotemporal evolution of gross ecosystem product (GEP) in Hebei Province, to provide a scientific basis for regional ecological conservation and sustainable development policies. Based on the ecological environment and socio-economic data of Hebei Province in 2015, 2020 and 2023, the GEP accounting system was employed to quantitatively assess the value of typical ecosystem services, followed by spatial variation analysis and an exploration of driving mechanisms. The results showed that from 2015 to 2023, the total GEP of Hebei Province exhibited a fluctuating trend, declining from 446.001 billion yuan to 412.124 billion yuan and then recovering to 421.454 billion yuan. Water conservation and carbon sequestration services accounted for the majority of ecosystem service value. A significant spatiotemporal disparity was observed in ecosystem services, with the Yanshan-Taihang Mountain region exhibiting prominent ecological regulation capabilities. The spatial variation of GEP in Hebei Province was closely associated with natural geography, policy regulation, and human activities. |
