山西重要地质遗迹空间分布特征及旅游响应

Spatial distribution characteristics and tourism response of important geological heritage in Shanxi

山西省地质遗迹资源丰富,地质旅游是地质遗迹科学保护与可持续利用的重要手段。本文运用最邻近指数、核密度分析和网格维等方法分析山西重要地质遗迹多尺度空间分布特征,并分别通过地理联系率和多尺度地理加权回归模型,从旅游发展响应和旅游空间响应两个维度分析地质遗迹的旅游响应特征。结果表明:(1)山西重要地质遗迹在省域、地域尺度呈核心集聚、外围扩散的带状分布格局,具有复杂的线性分形结构;市域尺度上呈集聚型和离散型“孤岛”状分布,各市分形结构分异明显。(2)旅游发展响应存在明显的尺度差异,地域尺度响应强度显著高于市域尺度。(3)重要地质遗迹对不同旅游要素的空间响应异质性显著,住宿条件和高A级景区数量为正向响应,夜间灯光强度为双向响应,旅游网络关注度、交通可达性和旅行社数量为负向响应。

Shanxi province is rich in resources of geological heritage,and geotourism is an important means for scientific protection and sustainable utilization of geological heritage.This paper firstly identifies the dense distribution areas of important geological sites in Shanxi through DBSCAN clustering algorithm of ArcGIS Pro software,and portrays the spatial distribution characteristics of important geological heritage in the province at multiple scales through the nearest neighbor index,kernel density analysis and grid dimensional method;secondly,it further explores the tourism development response and spatial response characteristics of important geological heritage using geographic linkage rate and multi-scale geographically weighted regression model.The results show that:(1)Shanxi's important geological heritage consists of seven major clustering distribution areas,and their distribution characteristics are significantly different in multi-scale perspectives.At the provincial scale,important geological heritage sites are clustered,showing"double main cores,several subcores,and block distribution"pattern,as well as a self-organized fractal structure around linear areas;at the regional scale,important geological heritage sites are clustered,showing a several cores distribution pattern,with a complex fractal structure around linear areas.On the scale of municipalities,the discrete and agglomerative distribution of important geological sites is obvious,showing an"island"distribution pattern.(2)The tourism development response of important geological heritage is significantly different in multi-scales.On the regional scale,the tourism development response of important geological sites is the highest,and the inbound tourism development response is slightly higher than that of domestic tourism,while the inbound tourism development response on the municipal scale is significantly lower than that of domestic tourism.On the scale of important geological sites,the response of inbound tourism is world level>provincial level>state level,and the response of domestic tourism is provincial level>state level>world level.(3)The tourism spatial response of important geological heritage has obvious scale effects and intensity differences.The response scales of tourism network concern and accommodation tend to be global scales;the number of high-Agrade scenic spots and nighttime light intensity are medium scales;the traffic accessibility and the number of travel agencies are smaller and spatial heterogeneity is obvious.In terms of response effects,the number of accommodation and high-A-grade scenic spots in important geological heritage agglomerations is higher,the nighttime light intensity has a positive and negative bidirectional response but weak response,and tourism network concern,traffic accessibility and the number of travel agencies show low levels in geological heritage agglomerations.
