As an important component of the value of rural ecological products, a fair assessment of rural ecotourism value is the only way to establish and improve the value realization mechanism of ecological products, practice "lucid waters and lush mountains are invaluable assets", and provide decision-making support for identifying the focus of rural revitalization and promoting the sustainable development of rural economy. The travel cost method (TCM) is used in this study to evaluate the regional tourist value of the research objects for rural ecotourism in Miyun District, Beijing, which are classified into three categories:homestay hotels, sightseeing parks, and rural hotels. The results show that Beijing is the primary tourist source for Miyun District, resulting in a large difference in sample size for each zone in the zonal travel cost method (ZTCM), which the travel cost interval analysis (TCIA) solves. And the TCIA is less influenced by individual bias than the individual travel cost method (ITCM), which makes the evaluation results more reasonable. The total value of rural ecotourism in Miyun District assessed by the TCIA is 4.245 billion yuan, of which the cost of expenses is 1.124 billion yuan, the time cost is 1.517 billion yuan, and the residual value is 1.604 billion yuan.
