山地型海岛乡村聚落空间形态三维量化研究——以宁波象山县南田岛为例

A Three-dimensional Quantitative Study on the Spatial Morphology of Rural Settlements on Mountainous Islands:A Case Study of Nantian Island in Xiangshan County,Ningbo City

海岛聚落的形态反映了在独特人居环境下的组织方式和演化规律,其成长驱动因素仍需科学研究。本文以浙江省宁波市象山县南田岛的53个乡村聚落为研究对象,其中山地聚落由于地形复杂性,展现了与平原聚落显著不同的竖向形态特征。然而,目前的研究普遍缺乏针对聚落三维形态的综合量化方法。为填补这一研究空白,本文在传统聚落二维平面空间形态研究的基础上,创新性地引入了竖向空间指标,构建了海岛山地聚落三维形态量化指标体系。同时,运用聚类分析方法对聚落空间形态进行了类型划分,深入探究了自然地理和人文社会因素对海岛山地聚落形态特征的影响。在此基础上,提出了聚落格局保护的空间发展策略,为海岛山地类型的乡村聚落保护和可持续发展提供了新的视角和方向。

The morphology of island settlements reflects the organization and evolutionary patterns under unique habitat environments,and their growth drivers still need to be scientifically studied.In this paper,53 rural settlements on Nantian Island,Xiangshan County,Ningbo City,are studied,in which mountainous settlements exhibit significantly different vertical morphological features from those on the plains due to the complexity of the terrain.However,current research generally lacks a comprehensive quantitative method for the three-dimensional morphology of settlements.In order to fill the research gap,this paper innovatively introduces vertical spatial indicators on the basis of the traditional two-dimensional planar spatial morphology study of settlements,and constructs a three-dimensional morphology quantification index system for mountain settlements on islands.At the same time,the cluster analysis method is used to classify the spatial morphology of settlements,and the influence of natural geography and socio-economic factors on the morphological characteristics of settlements in mountainous island is explored in depth.On this basis,spatial development strategies for the protection of settlement patterns are proposed,which provides a new perspective and direction for the protection and sustainable development of rural settlements in mountainous island regions.
