Spatial distribution characteristics and influencing factors of wine tourism resources in China

It is of great significance to creating a reasonable spatial distribution pattern of wine tourism resources to promote the healthy development of wine tourism in China and the high-quality development of tourism. With 7 086 wine tourism resources individual in China as the research object, the spatial distribution characteristics and influencing factors of wine tourism resources in China were analyzed and explored by using spatial statistical methods such as nuclear density analysis, nearest neighbor index, standard deviation ellipse and geographic detector. The results showed that China's wine tourism resources were basically bounded by the "Hu Huanyong Line". A spatial pattern of "more in the east, less in the west; denser in the south, sparser in the north" was observed, and the spatial agglomeration degree of the southeast side of the "Hu Huanyong Line" was higher than that the northwest side. The natural landscape category, the tourism purchase category and the overall wine tourism resources showed a northeast-southwest spatial distribution bias, while the humanistic landscape category and the exhibition and festival category wine tourism resources showed a northwest- southeast spatial distribution bias. The formation of the spatial pattern of China's wine tourism resources was a result of the joint action of many factors, and significantly influenced by the level of economic development. The study provided a scientific basis for optimizing the spatial distribution pattern of wine tourism resources in China.
