长江经济带旅游资源空间结构及其交通可进入性评价

Spatial Structure and Traffic Accessibility of Tourism Resources in Yangtze River Economic Belt

以长江经济带3A级及以上等级景区为例,利用最邻近指数、核密度分析以及加权网格维数对该区旅游资源的空间结构进行分析。通过构建旅游吸引力系数模型,建成考虑游客选择偏好的交通栅格成本数据集,利用成本距离分析工具对该区旅游资源的交通可进入性进行评价。研究表明:①旅游资源空间分布总体呈现东密西疏特征,其空间集聚存在明显的人口和社会经济偏好性,围绕省会城市及周边形成旅游资源显著集聚区。②旅游资源空间集聚整体呈现近轴对称形状,并形成以上海为核心的四大组团支撑,多中心协同的空间结构。③旅游资源的总体交通可进入性较好,但存在明显的东西空间差异,呈现出由东至西的阶梯状下降格局。④旅游资源的交通可进入性呈现出等级与类型差异,同时高交通可进入性旅游资源出现分省内部空间集聚,形成分省内部以省会城市为中心的近核心-外围结构。

Taking the scenic spots of grade 3 A and above in the Yangtze River Economic Belt as an example, the spatial structure of tourism resources in the Yangtze River Economic Belt was analyzed by using the nearest neighbor index,Kernel density analysis and weighted grid dimension. By constructing the tourism attraction coefficient model, a traffic grid cost dataset considering the preferences of tourists was built, then the traffic accessibility of tourism resources in the Yangtze River Economic Belt was evaluated by using the cost distance tool. The result shows that: 1) The spatial distribution of tourism resources is Dense in the east while sparse in the west. The spatial agglomeration has obvious population and socio-economic preferences, and a significant gathering area of tourism resources is formed around the provincial capitals and surrounding areas. 2) The spatial agglomeration of tourism resources presents an axisymmetric shape, and forms four supportive groups with Shanghai as the core, and a multi-center synergistic spatial structure. 3) The overall traffic accessibility of tourism resources is good, but there are obvious spatial differences between the east and west in this area, showing a step-like decline pattern from east to west. 4) The accessibility of tourism resources shows significant differences in grades and types. At the same time, high-traffic accessible tourism resources are clustered within the province’s internal space, forming a core-peripheral structure within the province that is centered on the provincial capital.
