[Method] The location set covering model (LSCM) provided by ArcGIS 10.0 was used in this study. [Result] After reconstruction, the settlement system in Dancheng County is composed of 2 county centers, 7 key towns and 122 key villages. [Conclusion] This study provides suggestions for the development of key settlements in Dancheng County, which contributes to improving the level of rural public services and ensuring social justice.展开更多
