摘　　要：退耕还林还草工程改善了黄河流域的生态环境,而快速的城镇化导致了严重的生境退化。采用生态系统服务功能模型、局部空间自相关分析和地理探测器,探索2000—2020年山西省沿黄19县生境质量的时空演变特征及其驱动机制。结果表明:①2000—2020年山西省沿黄19县生境质量从0.526上升到0.539,空间上形成低海拔生境质量较低,高海拔生境质量较高的分布格局;时间上南部生境质量相对稳定,中部、北部整体生境质量提高;生境退化度呈现南低北高的空间格局,且随着时间推移中低海拔区生境退化度升高。②局部空间自相关分析显示,生境质量和生境退化度在南部平原区为低低型集聚区,生境质量与生境退化度在北部高高集聚区互补。③地理探测分析发现,NDVI、地形(海拔、坡度)是影响山西省沿黄19县生境质量的主要因子;NDVI和坡度在2000年、2010年的交互作用最强,NDVI和年均气温在2020年交互作用最强。The long⁃term conversion of farmland to forests has improved the ecological environment of the Yellow River Basin,and rapid ur⁃banization has also led to serious habitat degradation.This paper integrated the ecosystem service function model(InVEST),local spatial au⁃tocorrelation analysis(Local Moran’s I)and geographic detector(Geodetector)to explore the temporal and spatial evolution of habitat quali⁃ty and its driving factors in 19 counties along the Yellow River in Shanxi Province from 2000 to 2020.The results show that a)from 2000 to 2020,the habitat quality index of 19 counties along the Yellow River in Shanxi Province is increased from 0.526 to 0.539,forming a spatial distribution pattern with low altitude and high altitude.The overall habitat quality in the north has been improved;the habitat degradation de⁃gree shows a spatial pattern of weak in the south and strong in the north,and habitat degradation in the middle and low altitude areas is in⁃creased with time.b)Local spatial autocorrelation analysis shows that both habitat quality and habitat degradation degree are LL⁃type agglom⁃eration in the southern plains,and complementary in the northern HH⁃type agglomeration.c)Geographical detection analysis finds out that NDVI and terrain(elevation,slope)are the dominant factors affecting the habitat quality of the 19 counties along the Yellow River in Shanxi Province;NDVI and the interaction of slope are the largest in 2000 and 2010,and the interaction between NDVI and annual average tempera⁃ture is the largest in 2020;the socioeconomic factors(population per unit area,GDP)and NDVI also have a strong synergistic effect.
