以中心地理论为依据，以河南省郸城县为例，探讨了县域范围内三级生活圈服务中心（县域中心、中心镇、中心村）的选择及其发展路径。首先，在确定各级服务中心地服务半径后，运用区位—配置模型，确定郸城县域服务圈由2个县域服务中心、7个中心镇和112个中心村组成。其次，根据基层干部的建议和农民意愿，提出了不同等级中心地公共服务设施配置的类型。最后，从政府投入、公众参与、企业社会责任等角度讨论了中心村镇公共服务的配套建设及其维护营运。

According the criteria of accessibility to the three levels of service centers, namely key village, the key town, and the county center, this study formulated a technical framework for key settlement selection. This study used the location and allocation model provided by ArcGIS10 and selected 2 county centers, 7 key towns, and 122 key villages.
