湖北省重要地质遗迹空间分布特征及其影响因素

Spatial Distribution Characteristics and Influencing Factors of Key Geoheritage Sites in Hubei Province

开展重要地质遗迹空间格局及影响因素分析,对地质遗迹研究与地质旅游产业发展具有重要意义。以湖北省334个重要地质遗迹为研究对象,运用平均最近邻指数、核密度分析、不平衡指数、空间自相关和地理探测器等工具,深入探讨了湖北省重要地质遗迹的空间分布特征及其驱动因素。结果表明:湖北省重要地质遗迹整体呈显著的聚集型分布特征,空间分布极不均衡,主要集中分布于鄂西宜昌、恩施、神农架和十堰等地;在全局尺度上,重要地质遗迹呈显著的空间正相关特征,但在局部空间上不同类型地质遗迹的空间聚集模式差异显著;地理探测器结果显示,矿产资源、地形条件、地貌条件、地层岩性、地质构造、旅游资源、居民经济条件、旅游收入等单因子的解释力高于0.2,是影响重要地质遗迹空间分布的主要因素,气候条件与地质构造、居民经济条件与旅游资源在交互后解释力高于0.7,是影响重要地质遗迹空间分布的主要因子组合。

Studying the spatial patterns and influencing factors of important geoheritage is crucial for advancing geoheritage research and developing the geotourism economy.This paper examines 334 important geoheritage sites in Hubei Province using tools such as the average nearest neighbor index,kernel density analysis,imbalance index,spatial autocorrelation,and geographic detector to explore their spatial distribution and driving factors.The results show that key geoheritage sites in Hubei Province exhibit a significant aggregated distribution pattern,with an uneven spatial distribution.These sites are primarily concentrated in areas such as Yichang,Enshi,Shennongjia,and Shiyan in the western part of the province.On a global scale,important geoheritage sites show a significant positive spatial correlation.However,at a local scale,the spatial aggregation patterns for different types of geoheritage vary significantly.Geographic detector results indicate that factors such as mineral resources,topographic and landform conditions,strata,lithology,tourism resources,economic conditions,tourism income,each with a single-factor explanatory power greater than 0.2,are the main determinants of the spatial distribution of geological relics.Additionally,interactions between climate conditions,geological structure,economic conditions,and tourism resources,with explanatory power exceeding 0.7,are also significant in influencing the spatial distribution of geological relics.
