辽西传统村落DSM空间形态

The spatial form of traditional villages DSM in western Liaoning

为了研究辽西传统村落空间形态,利用无人机遥感技术获取了辽西24个典型村落地形地貌、构筑物及植被等数据,在构建了传统村落数字地表模型(DSM)空间形态的长宽比系数、形状指数、饱和系数、公共空间分析维数、建筑密度及离散系数等6个指标体系基础上,运用地理信息系统(GIS)技术对辽西传统村落空间形态进行分析和评价,并运用聚落分析方法对其进行分类。结果得出辽西传统村落的带状倾向辐射型、团状倾向辐射型、团状集中型、团状分散型和带状集中型等5个类型空间形态。该成果对传统村落振兴发展及其人居环境保护提供了有益的借鉴。

In order to study the spatial form of traditional villages in western Liaoning, unmanned aerial vehicle(UAV) remote sensing technology was used to collect the data on topography and geomorphology, structure and vegetation of 24 typical villages in western Liaoning. The spacial form of western Liaoning traditional villages was analyzed and evaluated by geographic information system(GIS) as well as classified with settlement analysis based on the six index systems of length-width ratio coefficient, shape index, saturation coefficient, analysis of public space dimension, building density and coefficient of dispersion from the spacial form of the digital surface model(DSM) in the traditional villages.The results show that the traditional villages in western Liaoning had five types of spatial patterns: the ribbon tendency radiation type, the reunion tendency radiation type, the reunion tendency concentrated village, the reunion tendency dispersion type and the ribbon tendency concentration type. The result provides a useful reference to the revitalization of traditional villages and their human settlements protection.
