摘 要:自然资源禀赋优渥的承德市一直以来都是京津的生态安全保护屏障,林地作为承德市的主要生态支撑,其生态系统服务价值及驱动机制研究在京津冀协同发展战略中有着重要的生态安全意义。本研究基于InVEST模型和定量指标法综合核算2010年和2020年承德市林地二级地类,即有林地、灌木林地、疏林地、其他林地的生态系统服务价值,探究其变化特征,并借助地理探测器分析自然因素和社会经济因素对承德市林地生态系统服务价值的驱动作用。结果表明:(1)2020年承德市林地生态系统服务价值2693.71亿元,各类服务功能价值量差异较大,有林地(1557.37亿元,占比56.3%)与灌木林地(1028.89亿元,占比39.8%)是承德市林地生态系统服务价值的主要贡献者;(2)2010-2020年间承德市林地生态系统服务价值共增长154.06亿元,有林地生态贡献率最大,为82.47%;(3)自然因素与社会经济因素对各类林地影响效果不一,其中年降水对承德市林地生态价值的影响效果明显;而影响因素的交互作用相较单一因素作用而言,对承德市林地生态价值的影响有进一步增强,其中自然因素的交互作用效果占优。Chengde,with its rich natural resources endowment,had always been the ecological security protection barrier of Beijing and Tianjin.Woodland serves as the main ecological support of Chengde City,the research on its ecosystem service value and driving mechanism was of great ecological security significance in the Beijing-Tianjin-Hebei coordinated development strategy.In this work,the ecosystem service values of secondary woodland,namely forestland,shrubland,open woodland,and other woodland,were calculated for the years 2010 and 2020 by using InVEST model and quantitative index method in Chengde City.Besides,changing characteristics of the secondary woodland ecosystem were studied.Geospatial detectors were used to examine the socioeconomic and environmental aspects that were responsible for the service value of the woodland ecosystems in Chengde City.The results were as follows:(1)The value of woodland ecosystem services in Chengde City was worth 269.371 billion yuan and the value of various service functions was quite different in 2020.Forestland(155.737 billion yuan)and shrubland(102.889 billion yuan)were the main contributors to the value of woodland ecosystem services in Chengde City,which accounted for 56.3%and 39.8%,respectively.(2)The value of woodland ecosystem services in Chengde City had increased by 15.406 billion yuan from 2010 to 2020.The contribution rate of the forestland,reaching 82.47%,was the highest.(3)The effect of annual precipitation on the ecological value of woodland in Chengde City was obvious among natural and socio-economic factors that had different effects on various woodland.Compared with the single factor,the interaction of influencing factors had a more dramatic impact on the ecological value of Chengde City′s woodland.The interaction effect of natural factors was dominant among all factors.
