摘　　要：研究综合运用O-ring函数、GIS和地理探测器方法,分析不同尺度、不同地理分区黄河流域村庄空间分布及影响因素,为不同区域分类施治推进乡村高质量集约发展提供理论支撑。结果表明:(1)流域尺度上村庄呈现低密度小规模集聚。村庄密度由所在的第三级阶梯向第一级阶梯递减;东、中部经济带高于西部经济带;城市群普遍高于非城市群。(2)省、市、县单元村庄密度强烈正相关,流域流经的一级阶梯村庄呈HH聚集,二三级阶梯呈LL聚集。各省村庄空间分布在小尺度上集聚,大尺度上集聚、均匀和随机三种格局交替呈现。(3)年平均温度、年降水量、高程和GDP是流域村庄空间分布的主要影响因素,自然、经济、区位等因素对村庄空间分布的交互影响呈非线性增强或双因子增强。The study uses the O-ring function,GIS and geographical detector methods to analyze the spatial distribution and influencing factors of villages in the Yellow River basin at different scales and in different geographical zones,and to provide theoretical support for the classification and treatment of different regions to promote high-quality and intensive rural development.The results show that:(1)Villages at the watershed scale show low density and small-scale clustering.The density of villages decreases from the third level to the first level of the river basin;the eastern and central economic zones are higher than the western economic zones;urban clusters are generally higher than non-urban clusters.(2)The density of villages in the provincial,municipal,and county units is strongly positively correlated,with villages clustered in HH in the first level of the river basin and LL in the second and third levels.The spatial distribution of villages in each province is clustered at small scales,and the three patterns of clustering,uniformity,and randomness alternate at large scales.(3)Mean annual temperature,annual precipitation,elevation and GDP are the main influencing factors on the spatial distribution of villages in the basin,and the interaction effects of natural,economic and location factors on the spatial distribution of villages are nonlinearly enhanced or bi-factorially enhanced.
