为定量研究生态系统服务价值（ESV）空间分异演变及驱动因子耦合性作用。以沿海资源城市——唐山市为研究区域，基于1990—2015年土地覆被变化数据，在网格尺度下运用当量因子法、空间相关性分析和地理探测器探讨ESV空间演变特征。结果表明：从时间尺度看，唐山市ESV呈先下降再上升的趋势，近30年ESV共增加8.34亿元，城镇化是其波动的主要原因；耕地、林地和水域是ESV的主要组成部分，研究期间水域ESV增加23.13亿元。从空间尺度来看，唐山市ESV呈现中部低、南北高的空间分布特征，中部矿区生态系统功能脆弱，南部沿海湿地生态系统功能得到提高； ESV空间分布具有明显的正向空间聚集性和相关性。地理探测器结果表明：自然环境因子对ESV空间分异影响显著，土地利用程度解释力在30%以上，是空间分异的主要原因；高程和坡度解释力在20%以上，也发挥重要作用；交互作用类型主要为双因子交互增强和非线性增强，多因子交互作用相对单因子解释力明显增强。Conducting quantitative research on the spatial differentiation of ecosystem service value（ESV）and their driving factors is an effective way to achieve ecological and environmental balance. Taking the coastal resource city of Tangshan City as the study area and based on land cover change data from 1990 to 2015, the characteristics of the spatial evolution of ESV were explored at the grid scale using the equivalent factor method, spatial correlation, and geographic detector. The results showed that on a temporal scale, ESV in Tangshan City showed a decreasing and then increasing trend, with a total
