以长江中游城市群170个传统村落为研究对象,利用核密度法探讨城市群传统村落的空间分布特征,使用谷歌地图全球搜索引擎与相关公式测算各传统村落的可达性。运用地理空间计量方法 GWR回归模型重点剖析影响城市群传统村落可达性水平重要因子的具体影响程度并考量其空间异化效应。研究表明:(1)长江中游城市群传统村落存在三个高度集聚区,呈“品”形分布,其中有两大集聚区处于环鄱阳湖城市群内部。(2)传统村落可达性整体水平不高,时间成本较大,所在地区路网密度低,交通便利性不高,并受明显的支流效应影响,水系、山体和交通将一定程度上影响村落的可进入性水平。(3)地势高低与路网等级对传统村落可达性水平具有正向作用,邻水体距离对传统村落可达性水平呈负相关关系,而坡度值对可达性影响不显著。
Taking the 170 traditional villages in the urban agglomeration of the middle reaches of the Yangtze River as the research object, this paper uses the nuclear density method to explore the spatial distribution characteristics of the traditional villages in the urban agglomeration and uses the global search engine of Google Maps and related formulas to estimate the reachability of each traditional village. The geo-spatial measurement method GWR regression model is used to analyze the degree of influence of important factors affecting the traditional village reachability level of urban agglomerations and to consider the spatial alienation effect. The results show that: (1) There are three highly agglomerated areas in the traditional villages of urban agglomerations in the middle reaches of the Yangtze River, with a distribution of “products”, of which two agglomerations are located in the inner Poyang Lake metropolitan area. (2) The overall accessibility of traditional villages is not high, the time cost is high, the density of road network in the area is low, the traffic convenience is not high, and influenced by obvious tributary effects. The impacts of water system, mountain and traffic will affect villages to some extent The accessibility level. (3) The topography and the level of road network have a positive effect on the accessibility of traditional villages. The distance between adjacent water bodies is negatively related to the accessibility of traditional villages, and the influence of slope value on reachability is insignificant.
