摘要
山地县域村镇空间是农宅与公共服务设施落地的主要载体,也是国土空间规划与乡村振兴的基础单元。既有研究对山地县域村镇空间扩展适宜性及土地利用冲突关注不足,实证指导性低。本文以湖南省邵阳市绥宁县为例,构建“自然-人文”双维度村镇空间扩展适宜性指标体系,量化建设、农业、生态三类用地的倾向强度并划分高-中-低三档,建立土地利用冲突识别矩阵,形成冲突分区成果。结果发现:(1)绥宁县村镇空间扩展适宜性空间分异显著,极值相差5.84倍,等级梯度清晰;(2)扩展空间以“较不适宜”(28.52%)与“基本适宜”(30.44%)为主,二者合计近59%,“最适宜”区仅占5.06%,呈现“适宜面积小、差异大”的山地典型特征;(3)生态用地优势区中-高度倾向性占比达75.52%,且呈分散分布,生态保护压力突出;(4)潜在土地利用冲突区(冲突一般+冲突激烈)占县域49.46%,其中冲突一般区面积最大(49.45%),村镇-农业、生态-农业激烈冲突区面积最小(0.01%),风险总体可控但需重点监管。本研究通过协调土地开发、利用与保护的关系,可以山地县域国土空间规划编制提供可操作的技术路径,对促进乡村高质量振兴具有实践指导价值。
Rural settlement space in mountainous county serves as the primary carrier for placing rural residences and public service facilities,and constitutes a fundamental unit for territorial spatial planning and rural revitalization.Existing studies inadequately address the suitability of rural settlement expansion and land use conflicts in such regions,lacking empirical guidance.In this study,it took Suining County,Shaoyang City,Hunan Province,China as a case study.It constructed a natural-humanistic dual-dimensional suitability assessment framework for rural settlement expansion,quantify the development propensity intensity of construction,agricultural,and ecological land(categorized into high,medium,and low tiers via natural breaks classification),establish a land use conflict identification matrix,and generate conflict zoning outcomes.(1)Key findings reveal there was significant spatial differentiation of settlement expansion suitability in Suining County(extreme values differ by 5.84 times),with clear hierarchical gradation.(2)The expansion space was primarily composed of relatively unsuitable(28.52%)and basically suitable(30.44%)land,accounting for nearly 59%in total,while the most suitable land only accounts for 5.06%,presenting typical mountainous characteristics featured by small suitable area and large differences.(3)The proportion of medium-to-high propensity in ecology-dominance-land reached 75.52%,with a dispersed distribution,highlighting significant ecological protection pressures.(4)Potential land use conflict areas(general conflict+intense conflict)accounted for 49.46%of the county,with general conflict zones occupying the largest area(49.45%),and intense conflict zones merely taking the smallest areas(0.01%total),occurring at town-village land vs.agriculture land,ecology land vs.agriculture land.Therefore,the overall risk is controllable but requires focused supervision.By coordinating the relationships between land development,utilization,and protection,this study provides an operable technical pathway for the compilation of national spatial planning in mountainous counties and offers practical guidance for promoting high-quality rural revitalization.
