The establishment of National Trails is one way to protect and utilize corridors. In order to protect linear resources and improve China's National Trails system, we proposed a research method of ‘landscape convergence point - walking corridor - important corridor’. By constructing a comprehensive evaluation index for the suitability of National Trails, analyzing the suitable construction areas for National Trails, and setting up the minimum cumulative resistance (MCR) and gravity model to select potential routes for National Trails. Finally, conducting a comprehensive analysis of the relevant routes to determine the National Trails route selection. The results of the empirical study in Shandong province, for example, showed that 41 sections of National Trails with a total length of about 2200km were selected in Shandong province, crossing natural landscapes such as wetlands, mountains and hills, plains, oceans, and National Nature Reserves, as well as cultural heritages such as man-made canals, humanistic landscapes, and historical villages. The trails highlight the unique cultural and ecological pattern of Shandong Province, and the integration and mosaic of ecological diversity and cultural diversity.
