摘要

农村居民点是研究乡村人地关系的空间载体，其布局优化是推动乡村全面振兴的重要抓手和实现途径。以岩溶山区典型镇域毕节市七星关区撒拉溪镇的农村居民点图斑为研究对象，探讨增长极（发展活力集聚区）和发展轴（道路）对农村居民点空间布局的影响。结果表明：①撒拉溪镇农村居民点的发展活力空间分布差异较大，总体呈现以撒拉社区、冲锋村、水浸沟村、双龙村、龙场村和戈座村为主的分布态势；②撒拉溪镇农村居民点可划分为城乡融合、集聚发展、搬迁撤并、整治提升4类优化类型；③撒拉溪镇农村居民点可确定为经济中心区、乡村重构区、搬迁合并区、次级中心区4大优化区域。研究通过不同优化类型的空间指引和整合，可为岩溶山区镇域农村居民点的科学布局提供参考依据。

Abstract

Rural settlements serve as spatial carriers for studying human-land relationships in rural areas

and their layout optimization constitutes a crucial approach to promoting comprehensive rural revitalization. Using the rural settlement patches of Salaxi Town in Qixingguan District

Bijie City-a typical karst mountainous town-as a case study

this research examines the impacts of growth poles (areas with concentrated development vitality) and development axes (transport networks) on rural settlement spatial distribution. The findings indicate: ① Significant variations exist in the spatial distribution of development vitality across rural settlements in Salaxi Town

predominantly concentrated in the Sala Community

Chongfeng Village

Shuijinggou Village

Shuanglong Village

Longchang Village

and Gezuo Village; ② Rural settlements in Salaxi Town can be categorized into four optimization types: urban-rural integration

clustered development

relocation and consolidation

and improvement-oriented development; ③ The rural settlements in Salaxi Town can be categorized into four major optimization zones: the Economic Center Zone

the Rural Restructuring Zone

the Relocation and Consolidation Zone

and the Secondary Center Zone. Through spatial guidance and integration strategies tailored to different optimization types

this study provides reference insights for scientific planning of rural settlements in karst mountainous towns.
