明确旅游资源共享的公平程度对推动旅游业的高质量发展具有重要意义。本研究基于“区域公平”理念，创新构建了全民共享潜力测算模型，定量计算了全国居民享有国家5A级景区功能的潜力值，并探讨了空间公平的分布特征及影响因素。结果表明：(1)随着出游距离的增加，全国共享潜力区的数量不断增长，且在不同的出游距离下，其分布特征不同；(2)市域及省域尺度下的共享潜力区均以“胡焕庸线”为界呈现“东高西低”的空间格局；(3)“胡焕庸线”和“博台线”共同构成了共享潜力公平性分区格局的骨架；(4)景区数量、经济水平、交通条件与距离衰减效应之间存在动态交互机制，共同决定了景区共享潜力的空间格局。该研究可为国家5A级景区的空间格局优化提供科学依据。

Assessing the equity of tourism resource sharing is crucial for promoting high-quality tourism development. Based on the concept of "regional equity", this study innovatively constructed a model for measuring equitable public access potential. It quantitatively calculated the potential value for residents nationwide to enjoy the functions of national 5A-rated tourist attractions, and explored the spatial distribution characteristics of this fairness as well as its influencing factors. The results indicate that:(1) The number of equitable public access zones increases with travel distance, exhibiting distinct distribution characteristics under different distance thresholds.(2) At both municipal and provincial scales, the potential zones display a "higher in the east, lower in the west" spatial pattern, demarcated by the Hu Huanyong Line.(3) The Hu Huanyong Line and the Bole-Taipei Line jointly constitute the skeletal framework of the spatial equity partition.(4) A dynamic interactive mechanism exists among the number of scenic spots, economic development level, traffic conditions, and the distance decay effect, which jointly determine the spatial pattern of scenic spot sharing potential. This research can provide a scientific basis for optimizing the spatial layout of national 5A-rated tourist attractions.
