A scenic spot within a natural landscape is not only a spatial carrier of biodiversity but also an indispensable spatial element of culture. In the lower reaches of large river basins, natural protection and cultural development are both important, and merely identifying the importance of scenic spots in cultural or natural dimensions cannot support a structural understanding of the spatial importance of scenic spots at the landscape scale. Taking the scenic spots in the lower reach of the Yellow River as study objects, we built the cultural network, natural network and cultural-natural network to assess the importance of scenic spots based on connectivity. The scenic spots were grouped into four categories based on the relative importance of habitat connectivity and tourism connectivity. Three optimization scenarios, including the cultural, natural, and cultural-natural approaches, were set to indicate the impact of population, resistance and publicity on the importance of scenic spots. We found that the important nodes in each of the networks were clustered in different parts of the region. Only 1 of the 18 nodes belonged to the category in which habitat connectivity is important and tourism connectivity is not important, and 8 nodes belonged to the category in which habitat connectivity is not important and tourism connectivity is not important, which is the largest category. There were 5, 3 and 5 nodes whose importance increased by more than 5% in the cultural, natural and cultural-natural optimization scenarios, respectively. The network-based assessment method we provide can support landscape planning from a cultural-natural perspective.
