| 以河南省县域为研究对象，通过熵权法、空间自相关、局部自相关及地理探测器，探究河南省县域资源环境承载能力空间分异格局及空间相关性，并对其驱动力进行分析。结果表明：县域资源环境承载能力存在显著的空间分异特征，呈“块状”格局分布，地级市市辖区明显低于周边县市，西南至东北呈降低趋势。县域资源环境承载能力存在显著的空间正相关性，空间集聚特征明显。高〖CD*2〗低集聚区为焦作市修武县；高〖CD*2〗高集聚区集中在信阳市及驻马店市、洛阳市部分县区；低〖CD*2〗低集聚区集中在豫东、豫北及郑州市周边部分县市。人均耕地面积、人均GDP及城镇化率等是县域资源环境承载能力空间分异的主导驱动因子，且与其他驱动因子间的交互作用具有更强的驱动影响。 |

| Taking the counties in Henan as the research object， this study explored the spatial differentiation pattern and spatial correlation of resource environmental carrying capacity of the counties in Henan by using entropy weight method， spatial autocorrelation， local autocorrelation and geographic detector， and analyzed its driving forces. The results showed that the resource environmental carrying capacity of counties had significant spatial differentiation characteristics， presenting block distribution. It was significantly lower in municipal districts of prefecture level cities than those in their surrounding counties and cities， and showing a decreasing trend from southwest to northeast. 〖GK!86mm〗There was a significant spatial positive correlation in the resource environmental carrying capacity of counties， and their spatial agglomeration characteristics were obvious. High low agglomeration area was in Xiuwu County， Jiaozuo. High high agglomeration areas were concentrated in Xinyang， Zhumadian and some counties and districts of Luoyang. Low low agglomeration areas were concentrated in eastern and 〖HK〗〖HK〗northern parts of Henan， and some counties and cities around Zhengzhou. Per capita area of arable land， per capita GDP and urbanization rate were the main driving factors for the spatial differentiation of resource environmental carrying capacity of counties， and had a stronger driving effect when interacting with other driving factors. |
