南岭走廊瑶族乡村聚落边界形态特征分析

Morphological Characteristics of Yao Nationality Rural Settlement Boundary in Nanling Corridor

摘要:

选取南岭走廊地区 19 个瑶族代表性乡村聚落为研究样本，基于图底分析法，采用长宽比、形状指数和分维权数量化探析瑶族乡村聚落的边界形态和图形特征。结果表明，瑶族乡村聚落呈现出团状、团状倾向的指状、无明确倾向的指状 3 种边界形态特征；边界图形特征则呈现为平滑简单和破碎复杂 2 种状态，团状聚落的边界图形趋向于平滑简单，而团状倾向的指状和无明确倾向的指状聚落的边界图形更趋向于破碎复杂。究其原因，瑶族乡村聚落边界形态主要受地形地势、河流水系等自然因素和宗族文化、社会经济等人文因素影响。据此，提出了相关建议以促进南岭走廊瑶族乡村聚落保护与发展。

Abstract:

This study selected 19 representative Yao rural settlements in the Nanling Corridor area as research samples. Based on the map-based method, aspect ratio, shape index, and fractional quantification were used to analyze the boundary morphology and graphic characteristics of Yao rural settlements. The results show that Yao rural settlements exhibit three types of boundary morphological characteristics: cluster-like, cluster-like finger shaped, and finger-shaped with no clear tendency. The boundary graphic characteristics are presented in two states: smooth-simple and fragmented-complex. The boundary patterns of cluster-liked settlements tend to be smooth and simple, with cluster-like finger-shaped settlements and finger-shaped settlements with no clear tendency to be more fragmented and complex. The boundary shape of Yao rural settlements is primarily influenced by natural factors like topography and river systems, as well as human factors such as clan culture and social economy. Based on this, relevant suggestions are put forward to promote the preservation and development of Yao rural settlements in the Nanling Corridor.
