【摘要】 基于宁德市旅游资源数据，采用最邻近指数、核密度及地理探测器等方法探讨宁德市各类型旅游资源的空间特征及其空间可达性，并利用地理探测器对其可达性空间格局的影响因素进行探究。结果表明：(1)宁德市旅游资源空间分布呈“东部集聚、西部分散”分布特征，以福鼎、霞浦一带为核心的东北部区域核密度值较高。各类型旅游资源空间分布特征差异明显，其中建筑与设施类资源集聚程度最高，人文活动类资源最接近均匀离散分布。(2)宁德市旅游资源整体可达性较好且具有明显交通指向性，平均通行时间0.22 h,高可达性区的分布形态与境内主要交通干线走向基本一致，东部地区旅游资源可达性较西部更优。(3)旅游资源核密度因子对可达性空间差异的影响力最大。任意2种影响因子对旅游资源可达性差异的影响都呈双因子增强与非线性增强关系，并非简单的叠加效应且不存在独立或减弱关系。更多还原

【Abstract】 Based on the tourism resource data of Ningde City, this study explores the spatial characteristics and accessibility of various types of tourism resources in Ningde using the nearest neighbor index, kernel density, and geographic detectors.It also investigates the influencing factors of its accessibility spatial pattern using geographic detectors.The results show that:(1)The spatial distribution of tourism resources in Ningde is characterized by “astern agglomeration and western dispersion”,with the northeastern region centered around Fuding and Xiapu exhibiting higher kernel density values.Significant differences are observed in the spatial distribution characteristics of various types of tourism resources, with architecture and facilities showing the highest degree of resource agglomeration, while human activity resources are more uniformly dispersed.(2)Overall, Ningde’s tourism resources have good accessibility and display a clear orientation towards major transport routes.The average access time is 0.22 hours, and the distribution of high accessibility areas aligns closely with the main transportation arterials in the territory.The eastern region has better accessibility than the western region.(3)The kernel density factor of tourism resources has the greatest influence on the spatial difference in accessibility.The influence of any two factors on the accessibility differences of tourism resources shows a bi-factor enhancement relationship and nonlinear enhancement, rather than a simple superposition effect, with no independent or weakening relationships.更多还原
