基于数字化方法的滇西镇村聚落体系空间特征及类型研究——以大理云龙县为例

Research on the Spatial Characteristics and Type of Town and Village Settlement System inWestern Yunnan Province Based on Digital Method: A Case Study of Yunlong County in Dali

镇村聚落体系是指一定地域范围内由集镇和乡村共同组成的有机联系整体,具有协同效应和自组织性,其总体空间格局和细部形态特征受到地理、交通、经济、社会等多方面因素的影响。云南省大理白族自治州云龙县地处滇西少数民族山区,独特的地理及人文环境造就了多样的镇村聚落空间,对其镇村聚落体系空间特征进行研究能够丰富对山区镇村聚落体系空间的理论认知,为山区镇村体系规划提供实践基础。本文基于2020《云龙年鉴》及影像数据,运用数字化方法,从多维度、多尺度对其镇村聚落体系空间格局及形态特征进行了研究,通过耦合多元特征以乡镇为单元进行了类型划分,并分类探讨了空间优化对策。

Town and village settlement system refers to an organic whole composed of towns and villages in a certain area,which has synergistic effect and self-organization,and its overall spatial pattern and detailed morphological characteristics are affected by many factors such as geography,transportation,economy,and society.Yunlong County of Dali is located in the minority mountainous area of western Yunnan Province.The unique geographical and cultural environment has created a variety of town and village settlement spaces.Studying on the spatial characteristics of the town and village settlement system can enrich the theoretical cognition of the town and village settlement system space in the mountain area,and provide practical basis for the planning of the town and village system in the mountain region.Based on the 2020 Yunlong Yearbook and image data,this paper uses digital methods to study the spatial pattern and morphological characteristics of the settlement system in towns and villages from multiple dimensions and scales.By coupling multiple features,the types are classified by towns and villages,and the spatial optimization strategies are discussed.
