【摘要】：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。
[Abstract]:Taking 170 traditional villages in the middle reaches of the Yangtze River as the research object, the spatial distribution characteristics of the traditional villages in the urban agglomeration are discussed by using the kernel density method, and the accessibility of the traditional villages is estimated by using the global search engine of Google Maps and the relevant formulas.The GWR regression model is used to analyze the degree of influence of the important factors affecting the accessibility level of the traditional villages in urban agglomeration and to consider the spatial alienation effect.The study shows that there are three high concentration areas in the traditional villages in the middle reaches of the Yangtze River, which are "good", two of which are located in the interior of the Poyang Lake urban agglomeration.) the overall level of the traditional villages' accessibility is not high, and the time cost is high.In the region where the road network density is low, the traffic convenience is not high, and is affected by the obvious tributary effect, the water system,Mountain mass and traffic will affect the accessibility level of villages to some extent.) the terrain level and road network grade have positive effect on the traditional village accessibility level, and the distance between adjacent water body has a negative correlation with the traditional village accessibility level.However, the slope value had no significant effect on the reachability.
